Szczepionka przeciw covid-19
Leczenie
Szczepionki przeciw COVID-19, w tym preparaty mRNA (Pfizer-BioNTech, Moderna) oraz podjednostkowa białkowa (Novavax), wykazują wysoką skuteczność w zapobieganiu ciężkiemu przebiegowi choroby, hospitalizacji i zgonowi, osiągając odpowiednio 94-95% (Pfizer 95%, Moderna 94,1%) oraz około 90% skuteczności. Mechanizm działania szczepionek mRNA polega na wprowadzeniu instrukcji genetycznej do komórek, które syntetyzują białko kolca (spike protein), indukując odpowiedź immunologiczną z udziałem przeciwciał i limfocytów T, bez ryzyka infekcji czy ingerencji w genom. Szczepionka Novavax zawiera natomiast fragmenty białka kolca wraz z adjuwantem, stymulując odpowiedź immunologiczną tradycyjną metodą. Szczepienia są rekomendowane dla wszystkich osób powyżej 6 miesięcy, z indywidualizacją schematów dawkowania u osób z obniżoną odpornością, w tym pacjentów onkologicznych, u których dawki przypominające mogą zwiększyć poziom przeciwciał nawet 20-krotnie. Szczepionki są bezpieczne, a działania niepożądane są zazwyczaj łagodne i przemijające; rzadkie poważne zdarzenia, takie jak anafilaksja (2,5-11,1/1 mln dawek) czy zapalenie mięśnia sercowego, występują z niską częstością i są mniej prawdopodobne niż po naturalnym zakażeniu SARS-CoV-2.

Definicja i znaczenie szczepionki przeciw COVID-19
Szczepionka przeciw COVID-19 to preparat medyczny, którego celem jest przygotowanie układu odpornościowego organizmu do ochrony przed chorobą COVID-19. Szczepienia są kluczowym narzędziem w walce z pandemią SARS-CoV-2, umożliwiającym powrót do normalnego życia.1 Szczepionki przeciw COVID-19 obniżają ryzyko zachorowania, ciężkiego przebiegu choroby oraz zgonu.1 Wypracowanie skutecznych i bezpiecznych szczepionek było możliwe dzięki bezprecedensowej współpracy międzynarodowej społeczności naukowej.1
Głównym celem szczepienia jest wywołanie odpowiedzi immunologicznej organizmu poprzez wytworzenie przeciwciał, które będą zwalczać infekcję wirusem SARS-CoV-2. Szczepionki przeciw COVID-19 są bezpieczne i skuteczne, a ich działanie opiera się na wywołaniu produkcji białek zwanych przeciwciałami, które zwalczają zakażenie wirusem wywołującym COVID-19.1 Obecnie dostępne szczepionki są skuteczne w zapobieganiu ciężkiej chorobie, hospitalizacji i śmierci z powodu COVID-19, nawet w przypadku nowych wariantów wirusa.12
Rodzaje szczepionek przeciw COVID-19
Na rynku dostępnych jest kilka rodzajów szczepionek przeciw COVID-19, wykorzystujących różne technologie. Główne typy to szczepionki mRNA, wektorowe i podjednostkowe.12 W Stanach Zjednoczonych i Europie najczęściej stosowane są szczepionki: Pfizer-BioNTech, Moderna oraz Novavax.12
Szczepionki mRNA
Szczepionki mRNA, takie jak Pfizer-BioNTech (Comirnaty) i Moderna (Spikevax), wykorzystują technologię opartą na kwasie rybonukleinowym (mRNA).1 Wprowadzają do organizmu instrukcję genetyczną, która uczy komórki, jak wytworzyć białko S (spike protein) znajdujące się na powierzchni wirusa SARS-CoV-2.1 Po podaniu szczepionki mRNA wnika do komórek i dostarcza im instrukcje, jak wytworzyć nieszkodliwą kopię białka kolca wirusa. Następnie układ odpornościowy rozpoznaje to białko jako obce i wytwarza przeciwciała oraz limfocyty T, które będą zwalczać wirusa w przypadku przyszłej infekcji.12
Warto podkreślić, że szczepionki mRNA nie zawierają żywego wirusa i nie mogą wywołać choroby COVID-19.1 Nie wnikają również do jądra komórkowego i nie wpływają na materiał genetyczny człowieka.1
Szczepionki podjednostkowe
Szczepionka Novavax reprezentuje inną technologię – jest to szczepionka podjednostkowa białkowa. Zawiera fragmenty białka kolca wirusa SARS-CoV-2, które stymulują odpowiedź immunologiczną.1 W przeciwieństwie do szczepionek mRNA, Novavax wykorzystuje tradycyjną technologię szczepień, zawierając białko kolca wirusa sformułowane jako nanocząsteczka, która nie może wywołać choroby.1 Dodatkowo zawiera adjuwant, składnik wzmacniający ochronę immunologiczną.1
Szczepionka podjednostkowa działa w ten sposób, że organizm reaguje na wprowadzone białka, wytwarzając przeciwciała i limfocyty obronne.1 W badaniach klinicznych wykazała około 90% skuteczności, osiągając wyniki niemal równie dobre jak szczepionki mRNA we wczesnych próbach.1
Skuteczność szczepionek przeciw COVID-19
Szczepionki przeciw COVID-19 wykazały wysoką skuteczność w zapobieganiu ciężkiemu przebiegowi choroby, hospitalizacji i śmierci.1 W badaniach klinicznych szczepionki mRNA osiągnęły skuteczność na poziomie 94-95% (Pfizer – 95%, Moderna – 94,1%), natomiast Novavax wykazał skuteczność na poziomie około 90%.12
Badania wykazały, że szczepionki są skuteczne przeciwko różnym wariantom wirusa SARS-CoV-2, chociaż poziom ochrony może się różnić w zależności od konkretnego wariantu.1 Najnowsze wersje szczepionek są regularnie aktualizowane, aby lepiej chronić przed krążącymi wariantami wirusa.1 Przykładowo, w czerwcu 2024 r. FDA zaleciła aktualizację szczepionek przeciwko COVID-19, aby ukierunkować szczep wirusa COVID-19 zwany JN.1.1
Skuteczność u pacjentów z chorobami współistniejącymi
U osób z obniżoną odpornością, w tym pacjentów z chorobami nowotworowymi, szczepionki mogą być mniej skuteczne w porównaniu do populacji ogólnej, jednak nadal zapewniają istotną ochronę.1 Badania wykazały, że około 95% pacjentów onkologicznych poddawanych aktywnej terapii przeciwnowotworowej, w tym przeszczepowi komórek macierzystych, osiągnęło wymierną odpowiedź immunologiczną po szczepieniu.1
U pacjentów z obniżoną odpornością, którzy mogą nie wytworzyć wystarczającej odpowiedzi immunologicznej na standardowy schemat szczepienia, zalecane są dodatkowe dawki szczepionki.1 Dowody wskazują, że dawki przypominające mogą znacząco zwiększyć poziom przeciwciał – w jednym z badań stwierdzono nawet 20-krotny wzrost przeciwciał po trzeciej dawce, co sugeruje silną odpowiedź pamięciowych limfocytów B.1
Ochrona przed transmisją wirusa
Szczepionki przeciw COVID-19 mogą również zmniejszać ryzyko transmisji wirusa, chociaż ich głównym celem jest ochrona przed ciężkim przebiegiem choroby.1 Osoby zaszczepione mogą nadal zarazić się wirusem i zachorować (tzw. przełomowe zakażenie), ale objawy są zazwyczaj łagodniejsze niż u osób niezaszczepionych.12
Szczepionki donosowe, takie jak eksperymentalna NanoSTING-SN, są opracowywane z myślą o zapewnieniu lepszej ochrony przed transmisją dla wariantów COVID-19 i spokrewnionych sarbekowirrusów. W wielu modelach wykazano, że pojedyncze leczenie NanoSTING nie tylko chroni przed patogennymi szczepami SARS-CoV-2, ale także zapobiega transmisji wysoce zakaźnych wariantów, takich jak warianty Omikron.12
Bezpieczeństwo szczepionek przeciw COVID-19
Szczepionki przeciw COVID-19 przeszły rygorystyczne badania kliniczne i spełniają surowe normy bezpieczeństwa, jakości i skuteczności.1 Bezpieczeństwo szczepionek zostało dokładnie przeanalizowane zarówno u dorosłych, jak i u dzieci przez niezależne organy regulacyjne, takie jak amerykańska Agencja Żywności i Leków (FDA) oraz europejska Agencja Leków (EMA).12
Działania niepożądane
Większość działań niepożądanych po szczepieniu przeciw COVID-19 jest łagodna i ustępuje w ciągu kilku dni.1 Najczęstsze działania niepożądane to:
- Ból, zaczerwienienie i obrzęk w miejscu wstrzyknięcia12
- Zmęczenie12
- Ból głowy12
- Ból mięśni lub stawów12
- Dreszcze12
- Gorączka12
W rzadkich przypadkach mogą wystąpić poważniejsze działania niepożądane, takie jak reakcje alergiczne (anafilaksja) czy zapalenie mięśnia sercowego (zapalenie mięśnia sercowego i osierdzia).1 Ryzyko anafilaksji po szczepieniu przeciw COVID-19 jest jednak wyjątkowo niskie i wynosi około 2,5-11,1 przypadków na milion podanych dawek.1
W przypadku szczepionek mRNA zgłaszano rzadkie przypadki zapalenia mięśnia sercowego (zapalenie mięśnia sercowego i osierdzia), szczególnie u młodych mężczyzn.1 Ryzyko zapalenia mięśnia sercowego po szczepieniu przeciw COVID-19 jest jednak niskie i badania wskazują, że ryzyko zapalenia mięśnia sercowego jest nawet 6 razy wyższe po zakażeniu COVID-19 niż po szczepieniu mRNA.1
Bezpieczeństwo u pacjentów z obniżoną odpornością
Szczepionki przeciw COVID-19 są bezpieczne dla osób z osłabionym układem odpornościowym, w tym pacjentów z chorobami nowotworowymi.1 Badanie obejmujące ponad 400 osób leczonych na raka dostarcza dodatkowych zapewnień lekarzom i pacjentom o bezpieczeństwie szczepionek przeciw COVID-19.1
Osoby z chorobami nowotworowymi leczone pewnymi lekami immunoterapeutycznymi mogą otrzymywać szczepionki mRNA przeciw COVID-19 bez zwiększonego ryzyka działań niepożądanych związanych z układem odpornościowym, takich jak zapalenie płuc czy okrężnicy.1 Analiza dokumentacji medycznej pacjentów nie wykazała dowodów na to, by szczepienie przeciw COVID-19 zwiększało rodzaj, częstotliwość lub nasilenie działań niepożądanych związanych z układem odpornościowym.1
Nie ma dowodów, które sugerowałyby, że szczepionki przeciw COVID-19 powodują raka lub mogą sprawić, że nowotwór będzie rósł lub nawracał.1
Schematy dawkowania szczepionek
Schematy dawkowania szczepionek przeciw COVID-19 różnią się w zależności od wieku, stanu zdrowia oraz rodzaju szczepionki.1 Centra Kontroli i Zapobiegania Chorobom (CDC) zalecają, aby wszyscy w wieku 6 miesięcy i starsi otrzymali zaktualizowaną szczepionkę przeciw COVID-19 na sezon 2024-2025, która ukierunkowana jest na aktualnie krążące warianty wirusa.12
Zalecenia szczególne dla grup wysokiego ryzyka
Dla osób w wieku 65 lat i starszych oraz osób z osłabionym układem odpornościowym CDC zaleca drugą dawkę zaktualizowanej szczepionki przeciw COVID-19 po 6 miesiącach od pierwszej dawki.1 Jest to uzasadnione faktem, że osoby starsze oraz z obniżoną odpornością są bardziej narażone na ciężki przebieg COVID-19.1
Pacjenci z osłabionym układem odpornościowym, tacy jak osoby po przeszczepie narządów lub osoby leczone immunosupresyjnie, mogą wymagać dodatkowych dawek szczepionki.1 Zgodnie z zaleceniami CDC, osoby z umiarkowanie lub ciężko osłabionym układem odpornościowym powinny otrzymać dodatkowe dawki podstawowe szczepionki przeciw COVID-19.1
| Grupa wiekowa | Podstawowe zalecenie | Zalecenia dla osób z obniżoną odpornością |
|---|---|---|
| 6 miesięcy i starsi | 1 dawka szczepionki 2024-2025 | Może być zalecany schemat wielodawkowy |
| 65 lat i starsi | 1 dawka szczepionki 2024-2025, plus dawka przypominająca po 6 miesiącach | Schemat 3-dawkowy dla szczepionek Moderna lub Pfizer lub 2-dawkowy dla Novavax |
| Osoby z obniżoną odpornością (wszystkie grupy wiekowe) | Indywidualny schemat ustalany z lekarzem | Dodatkowe dawki i częstsze dawki przypominające |
Szczepienie po przebytym zakażeniu
Zaleca się szczepienie nawet osobom, które już przeszły COVID-19.1 Szczepienie po przebytym zakażeniu może zapewnić dodatkową ochronę przed wirusem i zmniejszyć ryzyko ponownego zakażenia.1
CDC zaleca, aby osoby, które niedawno przebyły zakażenie COVID-19, rozważyły opóźnienie dawki szczepionki o 3 miesiące od momentu pojawienia się objawów lub uzyskania pozytywnego wyniku testu.1 Odporność hybrydowa – odporność uzyskana zarówno z szczepienia, jak i wcześniejszego zakażenia COVID-19 – zwiększa ochronę przed ciężkimi następstwami przyszłych zakażeń COVID-19 i oferuje dłuższą ochronę niż samo zakażenie.1
Szczepienia u pacjentów otrzymujących leczenie immunosupresyjne
Pacjenci otrzymujący leczenie immunosupresyjne stanowią szczególną grupę, która wymaga indywidualnego podejścia do szczepień przeciw COVID-19.1 Leki immunosupresyjne mogą wpływać na odpowiedź immunologiczną organizmu na szczepionkę, co może prowadzić do zmniejszonej skuteczności szczepienia.1
Wpływ terapii na skuteczność szczepienia
Udowodniono naukowo, że terapia immunosupresyjna hamuje odpowiedź humoralną na szczepionki przeciwko innym czynnikom zakaźnym, takim jak grypa, pneumokok i wirusowe zapalenie wątroby typu B. Doprowadziło to do hipotezy, że to samo może się zdarzyć w przypadku szczepionki przeciw COVID-19.1
Przeprowadzono szereg badań w tym obszarze, które sugerują, że tymczasowe przerwanie podawania metotreksatu przez 2 tygodnie po szczepieniu może poprawić odpowiedź na szczepionkę. Podobne wyniki uzyskano dla innych leków immunosupresyjnych.1 Badania obserwacyjne wykazały, że pacjenci przyjmujący rytuksymab (lek szeroko stosowany u pacjentów z chłoniakiem) lub podobne leki słabo reagują lub wcale nie reagują na szczepionki przeciw COVID-19 mRNA, jeśli są one podawane po leczeniu.1
Zalecenia dotyczące czasowego wstrzymania leków
W przypadku niektórych leków immunomodulujących zaleca się tymczasowe wstrzymanie ich stosowania w czasie szczepienia przeciw COVID-19.1 Oto przykładowe zalecenia:
- Metotreksat: Wstrzymać przyjmowanie przez 7 dni po każdej dawce szczepionki. Można wznowić przyjmowanie leku 8 dnia po każdej dawce szczepionki.1
- Rytuksymab: U pacjentów, którzy otrzymali rytuksymab 6 lub mniej miesięcy przed szczepieniem, nie wytwarzają się przeciwciała blokujące. Zaleca się szczepienie co najmniej 7 dni po ostatniej dawce rytuksymabu.1
- Abatacept (Orencia): Zaleca się zaplanowanie pierwszej dawki szczepionki co najmniej 7 dni po ostatniej dawce Orencia. Po otrzymaniu pierwszej dawki szczepionki należy wstrzymać Orencia przez 7 dni. Można wznowić przyjmowanie Orencia 8 dnia po pierwszej dawce szczepionki.1
W przypadku innych leków reumatologicznych, takich jak Plaquenil (hydroksychlorochina), Arava (leflunomid), sulfasalazyna, prednizon, Otezla, Enbrel, Humira, Simponi, Cimzia, Remicade, Actemra, Kevzara, Cosentyx, Taltz, Stelara, Prolia, Reclast, Evenity, Forteo czy niesteroidowe leki przeciwzapalne (NLPZ), można kontynuować ich przyjmowanie według normalnego schematu, bez przerywania w trakcie szczepienia przeciw COVID-19.1
Ważne jest, aby każde szczepienie zostało zindywidualizowane dla każdego pacjenta, rozważając korzyści płynące z czasowego odstawienia leków modyfikujących przebieg choroby (DMARD) w porównaniu z ryzykiem potencjalnych zaostrzeń choroby. Dowody dostępne w literaturze przemawiają za tą strategią, ponieważ wiązała się ona z wzmocnioną odpowiedzią humoralną i komórkową na szczepionkę przeciw COVID-19, przy niewielkiej częstości zaostrzeń, które były głównie łagodne w nasileniu.1
Leczenie COVID-19 a szczepienia
Szczepienia przeciw COVID-19 i leczenie COVID-19 to dwa odrębne, ale uzupełniające się podejścia w walce z pandemią. Warto podkreślić, że szczepienia są pierwszym krokiem w zapobieganiu ciężkim następstwom zdrowotnym. Leczenie przeciwwirusowe nie zastępuje szczepień przeciw COVID-19.1
Terapie przeciwwirusowe
Amerykańska FDA zatwierdziła lub autoryzowała kilka leków przeciwwirusowych stosowanych w leczeniu łagodnego do umiarkowanego COVID-19 u osób, które są bardziej narażone na bardzo ciężki przebieg choroby.1 Leki przeciwwirusowe działają na określone części wirusa, aby zatrzymać jego namnażanie się w organizmie po zakażeniu, pomagając zapobiec ciężkiej chorobie i śmierci.1
Główne terapie przeciwwirusowe stosowane w leczeniu COVID-19 to:
- Paxlovid (nirmatrelvir z rytonawirem) – lek doustny zatwierdzony do leczenia łagodnego lub umiarkowanego COVID-19 u dorosłych i dzieci w wieku 12 lat i starszych, którzy są narażeni na wysokie ryzyko progresji do ciężkiego COVID-19. Leczenie musi rozpocząć się w ciągu pięciu dni od wystąpienia objawów.1
- Remdesivir (Veklury) – lek dożylny, zatwierdzony zarówno dla dorosłych, jak i dzieci, podawany przez trzy kolejne dni w ośrodku opieki zdrowotnej. Leczenie musi rozpocząć się w ciągu siedmiu dni od wystąpienia objawów.1
- Lagevrio (molnupiravir) – lek doustny dla dorosłych, który muszą zacząć przyjmować w ciągu pięciu dni od wystąpienia objawów.1
Leczenie musi być rozpoczęte w ciągu 5-7 dni od pojawienia się pierwszych objawów, aby było skuteczne.1 Osoby zakażone, ale leczone poza szpitalem, mogą otrzymać Paxlovid (tabletki nirmatrelvir i tabletki rytonawir, zapakowane do podawania doustnego) w celu leczenia COVID-19 u określonych dorosłych.1
Terapie immunomodulujące
Terapie immunomodulujące odgrywają kluczową rolę w umiarkowanym do ciężkiego przebiegu COVID-19.1 Obejmują one różne leki, od sterydów po hydroksychlorochinę, tocilizumab i anakinrę.1
Dla określonych hospitalizowanych dorosłych z COVID-19, FDA zatwierdziła również Olumiant (baricitinib) i Actemra (tocilizumab).1 Te leki immunomodulujące mają na celu modyfikację odpowiedzi immunologicznej organizmu na wirusa, co może pomóc w zapobieganiu nadmiernej reakcji zapalnej obserwowanej w ciężkich przypadkach COVID-19.
Zastosowanie kortykosteroidów poprawia przeżycie u hospitalizowanych pacjentów z ciężkim COVID-19 wymagających suplementacji tlenem, przy czym największą korzyść wykazano u osób wymagających wentylacji mechanicznej.1
Przeciwciała monoklonalne
FDA autoryzowała profilaktyczne przeciwciało monoklonalne dla osób z umiarkowaną lub ciężką immunosupresją, w wieku 12 lat i starszych, ważących co najmniej 40 kg. Oprócz szczepienia, Pemivibart (Pemgarda) może zapewnić dodatkową warstwę ochrony przed COVID-19 i może być podawany co najmniej 2 tygodnie po otrzymaniu szczepionki przeciw COVID-19.1
Pemgarda nie zastępuje szczepienia u osób, którym zaleca się szczepienie.1 Osoby przyjmujące sterydy w dużych dawkach i leki biologiczne o działaniu immunosupresyjnym lub immunomodulującym, takie jak terapie deplecyjne limfocytów B, kwalifikują się do otrzymania Pemgarda.1
W przypadku osób z osłabionym układem odpornościowym, które otrzymały leczenie przeciwwirusowe i nadal doświadczają objawów COVID-19, lekarz może zalecić dodatkowe leczenie, w tym osocze ozdrowieńców.1
Szczepienia w specjalnych grupach pacjentów
Pacjenci z chorobami onkologicznymi
Osoby chorujące na nowotwory (lub z historią nowotworów) mogą bezpiecznie otrzymać szczepionkę przeciw COVID-19. Jednakże szczepionka może być mniej skuteczna u niektórych osób z nowotworami.1 CDC i inne grupy ekspertów generalnie zalecają, aby wszystkie osoby, w tym osoby z rakiem i osoby, które przeżyły raka, były na bieżąco z najnowszymi szczepionkami przeciw COVID-19.1
Memorial Sloan Kettering Cancer Center (MSK) i Centra Kontroli i Zapobiegania Chorobom (CDC) zalecają, aby osoby chorujące na raka regularnie otrzymywały szczepienia przeciw COVID-19.1 Szczepionka przeciw COVID-19 na lata 2024-2025 jest ukierunkowana na warianty, które obecnie krążą i które spodziewane są w sezonie jesienno-zimowym.1
CDC twierdzi, że osoby z umiarkowanie lub ciężko osłabionym układem odpornościowym są narażone na zwiększone ryzyko ciężkiej choroby COVID-19.1 Jeśli otrzymałeś jakiekolwiek szczepienia przeciw COVID-19 przed, w trakcie lub krótko po leczeniu przeciwnowotworowym, może być konieczne ponowne szczepienie, jeśli twój lekarz uważa, że twój układ odpornościowy wystarczająco się odbudował, aby zareagować na szczepionki.1
Kobiety w ciąży i karmiące piersią
CDC zaleca szczepienia przeciw COVID-19 dla osób, które: planują lub starają się zajść w ciążę, są obecnie w ciąży, lub karmią piersią.1 Szczepienie przeciw COVID-19 jest zalecane kobietom w ciąży, karmiącym piersią, starającym się zajść w ciążę lub które mogą zajść w ciążę, aby zapobiec zachorowaniu na ciężką postać COVID-19. Szczepienie w czasie ciąży chroni również niemowlęta przed ciężkim przebiegiem COVID-19, zanim będą wystarczająco dorosłe, aby zostać zaszczepione.1
Szczepienie podczas ciąży jest bezpieczne. Przynosi również korzyści dziecku, ponieważ umożliwia przekazanie wytworzonych przeciwciał od matki do dziecka.1 Nie ma dowodów, które sugerowałyby, że szczepionki przeciw COVID-19 wpływają na płodność.1
Pacjenci z chorobami autoimmunologicznymi
Osoby z chorobami autoimmunologicznymi powinny otrzymać szczepionkę przeciw COVID-19.1 Szczepionki przeciw COVID-19 są bezpieczne dla osób stosujących leki modyfikujące przebieg choroby (DMT). Należy kontynuować terapię modyfikującą chorobę (DMT), chyba że lekarz prowadzący zaleci jej przerwanie lub opóźnienie. Przerwanie niektórych DMT nagle może spowodować poważne zwiększenie niepełnosprawności i nowe zmiany. Na podstawie danych z wcześniejszych badań innych szczepionek i DMT, otrzymanie szczepionki przeciw COVID-19 podczas stosowania dowolnego DMT jest bezpieczne.1
Osoby z umiarkowaną do ciężkiej immunosupresją powinny otrzymać szczepienie przeciw COVID-19.1 Szczepionki okazały się najlepszą dostępną obroną przed powikłaniami COVID-19 wirusa SARS-CoV-2, w tym wszystkimi jego wariantami.1
Znaczenie szczepień w kontekście całościowej strategii walki z COVID-19
Szczepionki przeciw COVID-19 pozostają najskuteczniejszym narzędziem do kontrolowania rozprzestrzeniania się SARS-CoV-2 i pomagają ludzkości powrócić do normalnego życia.1 Chociaż leczenie COVID-19 odgrywa istotną rolę w redukcji ciężkości choroby u osób zakażonych, to właśnie powszechne szczepienia populacji okazały się najlepszym sposobem na przezwyciężenie pandemii SARS-CoV-2.1
Szczepienia przeciw COVID-19 zapewniają ochronę przed ciężką chorobą, hospitalizacją i śmiercią.1 Ponadto mogą zmniejszyć długoterminowe ryzyko powikłań sercowo-naczyniowych po COVID-19.1 Są również mniej ryzykownym sposobem na uzyskanie ochrony w porównaniu do zachorowania na COVID-19.1
Nadzór genomowy jest nadal potrzebny do wczesnego wykrywania wariantów, które mogą uniknąć przeciwciał neutralizujących, aby szczepionki mogły być odpowiednio aktualizowane.1 Ten ciągły proces aktualizacji szczepionek jest kluczowy dla utrzymania ich skuteczności wobec nowych wariantów wirusa.
Podsumowując, szczepionki przeciw COVID-19 stanowią fundament globalnej strategii walki z pandemią. Ich bezpieczeństwo i skuteczność zostały potwierdzone w licznych badaniach. Szczepienia, w połączeniu z dostępnymi metodami leczenia, oferują najlepszą ochronę przed COVID-19, zwłaszcza dla osób z grup wysokiego ryzyka, takich jak pacjenci z obniżoną odpornością czy chorobami współistniejącymi.

- #1 COVID-19 therapy and vaccination: a clinical narrative reviewhttps://pmc.ncbi.nlm.nih.gov/articles/PMC9914077/
The SARS-CoV-2 pandemic is the most globally impacting health issue our world has faced over the last century. […] Since the beginning of the pandemic, the scientific medical community has worked on therapeutic procedures that interfere with the exaggerated immune response. […] Immunomodulatory therapies are still crucial in moderate to severe COVID-19. Immunomodulator therapies include various medications from steroids to hydroxychloroquine, tocilizumab and Anakinra. […] Convalescent plasma, immunoglobulins, eculizumab, neutralizing IgG1 monoclonal antibodies and remdesivir have positively impacted inpatient mortality and hospital length of stay. […] Eventually, wide population vaccination was proven to be the best tool to overcome the SARS-CoV-2 pandemic and help humanity return to regular life.
- #1 Different types of COVID-19 vaccines: How they workhttps://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/different-types-of-covid-19-vaccines/art-20506465
COVID-19 vaccines lower your risk of getting sick, seriously ill or dying from the disease. […] Each COVID-19 vaccine causes the immune system to create proteins called antibodies. These proteins fight infection with the COVID-19 virus. […] An mRNA vaccine gives cells instructions for how to make the S protein found on the surface of the COVID-19 virus. […] This causes the body to create antibodies. Then if you catch the COVID-19 virus, these antibodies are used to help clear out the virus. […] Once the immune system recognizes the S proteins, it creates antibodies and defensive white blood cells. If infection with the COVID-19 virus happens later, the antibodies help clear out the virus. […] The Novavax COVID-19 vaccine is a protein subunit vaccine. […] Getting vaccinations as they are updated and on schedule gives you the best protection against COVID-19.
- #1 Comparing the COVID-19 Vaccines: How Are They Different? > News > Yale Medicinehttps://www.yalemedicine.org/news/covid-19-vaccine-comparison
Note: The Johnson Johnson (Janssen) COVID-19 vaccine expired as of May 6, 2023, and is no longer available in the U.S. Those who did get the JJ shot are considered up-to-date when they get one updated (20232024 formula) COVID vaccine. […] The good news is that vaccines, which have been updated each year since 2022, are still expected to be effective at preventing severe disease, hospitalization, and death from COVID. […] In the U.S., infants, children, and adults ages 6 months and older are eligible to be vaccinated, according to the Centers for Disease Control and Prevention (CDC). […] The Pfizer-BioNTech vaccine (brand name: Comirnaty) was granted full Food and Drug Administration (FDA) approval in August 2021 for people ages 16 and older. […] This is a messenger RNA (mRNA) vaccine, which uses a relatively new technology.

Yes. Catching the virus that causes COVID-19 or getting a COVID-19 vaccination gives you protection, also called immunity, from the virus. But over time, that protection seems to fade. The COVID-19 vaccine can boost your body’s protection. […] Researchers continue to study what happens when someone has COVID-19 a second time. Later infections are generally milder than the first infection. But severe illness can still happen. Serious illness is more likely among people older than age 65, people with more than four medical conditions and people with weakened immune systems. […] The COVID-19 vaccines available in the United States are: Pfizer-BioNTech COVID-19 vaccine 2024-2025 formula, available for people age 6 months and older. Moderna COVID-19 vaccine 2024-2025 formula, available for people age 6 months and older. Novavax COVID-19 vaccine 2024-2025 formula, available for people age 12 years and older.

In July 2022, this vaccine was found to be safe and effective and became available under an emergency use authorization for people age 18 and older. […] COVID-19 vaccines help the body get ready to clear out infection with the virus that causes COVID-19. […] Both the Pfizer-BioNTech and the Moderna COVID-19 vaccines use genetically engineered messenger RNA (mRNA). […] The Novavax COVID-19 adjuvanted vaccine is a protein subunit vaccine. […] With a protein subunit vaccine, the body reacts to the proteins and creates antibodies and defensive white blood cells. […] No. The COVID-19 vaccines available in the U.S. don’t use the live virus that causes COVID-19. Because of this, the COVID-19 vaccines can’t cause you to become sick with COVID-19. […] Some people have no side effects from the COVID-19 vaccine. For those who get them, most side effects go away in a few days.
- #1 How does the COVID-19 vaccine work | Ohio State Medical Centerhttps://wexnermedical.osu.edu/infectious-diseases/covid-19/schedule-your-vaccine/how-the-covid-19-vaccine-works
The COVID-19 vaccine is safe and effective. We know this because our experts have dedicated their lives to studying how infectious diseases and vaccines work. While the COVID-19 vaccines are relatively new, the mRNA technology they use has been studied and refined for decades. […] The vaccine contains messenger RNA made with the genetic code of spike proteins. When you’re injected with the vaccine, this messenger RNA enters your cells and produces a protein to stimulate an immune response, similar to COVID-19. […] Now if you encounter the real virus, your body will recognize COVID-19 and is trained to fight it.

- #1 COVID-19 Vaccination and Immunosuppressive Therapy in Immune-Mediated Inflammatory Diseaseshttps://pmc.ncbi.nlm.nih.gov/articles/PMC10747214/
The COVID-19 vaccination program has probably been the most complex and extensive project in history until now, which has been a challenge for all the people involved in the planning and management of this program. Patients with immune-mediated inflammatory diseases (IMIDs) on immunosuppressive therapy have required special attention, not only because of the particular haste in carrying out the process but also because of the uncertainty regarding their response to the vaccines. […] We now have strong scientific evidence that supports the hypothesis that immunosuppressive therapy inhibits the humoral response to vaccines against other infectious agents, such as influenza, pneumococcus and hepatitis B. This has led to the hypothesis that the same could happen with the COVID-19 vaccine. Several studies have therefore already been carried out in this area, suggesting that temporarily discontinuing the administration of methotrexate for 2 weeks post-vaccination could improve the vaccine response, and other studies with various immunosuppressive drugs are in the same line. However, the fact of withholding or interrupting immunosuppressive therapy when dealing with COVID-19 vaccination remains unclear. On this basis, our article tries to compile the information available on the effect of immunosuppressant agents on COVID-19 vaccine responses in patients with IMIDs and proposes an algorithm for the management of these patients.

Rituximab, a drug widely used in patients with lymphoma, blunts or eliminates the antibody response to COVID-19 vaccines if it is administered before them, Stanford researchers say. […] People who have been treated with rituximab, a widely used cancer drug, or similar drugs respond poorly or not at all to subsequent COVID-19 mRNA vaccines, according to a study by researchers at Stanford Medicine. […] The findings strongly suggest that people who are newly diagnosed with lymphoma should be offered the vaccine prior to beginning rituximab or similar drugs. […] „We found that antibody responses to the COVID-19 vaccine were blunted in people who received rituximab up to a year before vaccination. But if they were vaccinated prior to treatment, most responded and were able to hold on to that response during their rituximab treatment.”

The researchers found that, overall, 55% of the 126 patients developed antibodies that could block the virus’s spike protein from binding to its receptor in a laboratory dish. But none of the 31 patients who received rituximab six or fewer months before being vaccinated generated any blocking antibodies. […] The time elapsed since a patient’s last rituximab treatment – a span that varied between mere days and 18 years – was a significant predictor of vaccine response. […] The researchers predict they would also likely interfere with the COVID mRNA vaccines. […] Ten of these patients generated a blocking antibody response to the virus. In six of them, that response persisted at least four months after they started rituximab treatment. […] Our study suggests this practice of extended treatment should probably be abandoned in the COVID era.

Overall, any vaccination needs to be individualized to each patient, weighing the benefits of transiently stopping DMARDs against the risks of potential flares of the disease. The evidence available in the literature is in favor of this strategy as it has been associated with enhanced humoral and cellular responses to the COVID-19 vaccine, with a scarce incidence of flares, which were mostly mild in intensity. However, more research is needed on the clinical relevance of these findings in terms of decreasing the incidence and severity of subsequent COVID infections, although preliminary data suggest a trend towards a beneficial effect.
