  Hepatitis B vaccine recombinant is used to prevent infection by the hepatitis B virus. The vaccine works by causing your body to produce its own protection (antibodies) against the disease. […] This vaccine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you or your child have a rash, itching, swelling of the tongue and throat, or trouble breathing after you get the injection. […] Check with your doctor or nurse immediately if any of the following side effects occur: Fever of 37.7 degrees C (100 degrees F) or higher. […] Aches or pain in the joints, fever, or skin rash or welts (may occur days or weeks after receiving the vaccine). […] Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them: Dizziness, headache, soreness at the injection site. […] Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

  Hepatitis B is a vaccine-preventable liver infection caused by HBV. Hepatitis B can range from a mild, short-term, acute illness lasting a few weeks to a serious, long-term, chronic infection. […] Common side effects include pain, soreness, redness, or swelling in the arm where the shot was given. Headache. Fever. Fatigue. Irritability, diarrhea, loss of appetite in healthy infants and children who received (Recombivax, Vaxelis, Pediarix). Vomiting, crying, drowsiness in children (Vaxelis, Pediarix). […] Vaccines, like any medicine, can have side effects. Many people who get a hepatitis B vaccine have no side effects at all. The most common side effects include injection site pain, soreness, or redness, headache, and fatigue, and are usually mild lasting 1-2 days. […] A Vaccine Safety Datalink (VSD) study compared deaths among newborns vaccinated with hepatitis B and unvaccinated newborns. The study found no differences between vaccinated and unvaccinated newborns.

  https://healthify.nz/medicines-a-z/h/hepatitis-b-vaccine

  Hepatitis B vaccine gives protection against infection from the hepatitis B virus. The vaccine works by causing the body to produce antibodies against the virus responsible for hepatitis B infection and in this way protects (or provides immunity) against the disease. […] Like all medicines, vaccines can cause side effects, although not everyone gets them. […] Pain, swelling and redness at the injection site (hard and sore to touch) […] It’s quite common for the first 1 or 2 days after receiving the injection and usually settles within a few days.

  Hepatitis B vaccines are used to prevent hepatitis B, a viral infection of the liver that can lead to cirrhosis, liver failure, and liver cancer in some people. […] Hepatitis vaccines may cause side effects, although they tend to be mild and resolve within a day or two. Severe side effects are rare.

They include: Injection site pain, Injection site swelling, Headache, Fatigue, Malaise, Nausea, Diarrhea, Dizziness, Fever over 100 degrees F. […] Injection site reactions are more common with Heplisav-B, in part because it contains a substance called cytosine phosphoguanine. This acts as an adjuvant, an ingredient that amplifies the body’s response to vaccines. […] Severe side effects of hepatitis vaccines are rare. According to the World Health Organization, there is no evidence of serious adverse events linked to hepatitis B vaccination. This includes the risk of a potentially life-threatening allergic reaction known as anaphylaxis. […] Statistically, the risk of anaphylaxis among vaccine recipients is in the ballpark of 1.1 cases per million vaccine doses.

  HBV-infected individuals are often asymptomatic. Clinical symptoms of acute HBV infection are more likely in older individuals than in younger individuals. When manifested, symptoms may include fever, fatigue, nausea, vomiting, and abdominal pain before progressing to clay-colored stools, dark urine, and jaundice indicating increased liver involvement and cholestasis—the accumulation of bile in the liver. Extrahepatic manifestations of hepatitis B can include arthritis, urticaria, vasculitis, and glomerulonephritis. Symptomatic infection generally presents within the first 6 months of exposure averaging 90 days from exposure to jaundice and 60 days to abnormal serum alanine aminotransferase (ALT) levels indicating liver injury. […] Approximately 95 percent of all hepatitis B infections among otherwise healthy adults resolve without sequelae, and the recovered individual possesses lifelong immunity to HBV infection. In the other 5 percent, chronic infection develops. Chronic HBV infection may lead to liver cirrhosis, liver failure, hepatocellular carcinoma, or death. These outcomes are thought to be the result of the constant activity of the immune system and not a direct consequence of damage caused by the virus itself. The likelihood of chronic hepatitis B disease is inversely related to the age of the individual at the time of HBV infection. Among infants perinatally infected with HBV, 80-90 percent develop chronic disease; among children infected postnatally through 5 years of age, 30 percent; and among adults, fewer than 5 percent. The risk of chronic disease may be higher in the immunocompromised and diabetics dependent on finger-stick monitoring devices.

  CDC reviewed VAERS reports of adverse events following hepatitis B vaccination from 2005 through 2015. During that time, 20,231 reports following hepatitis B or hepatitis B-containing vaccines, were submitted to VAERS. Over half of reports were in persons younger than 2 years of age; the majority of reports (78%) were following hepatitis B-containing vaccines in combination with other vaccines at the same visit. The most frequently reported adverse events for vaccines given in combination were fever, injection site redness, and vomiting.

  Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). For most people, hepatitis B is short term, also called acute. Acute hepatitis B lasts less than six months. But for others, the infection lasts more than six months and is called chronic. Chronic hepatitis B raises the risk of liver failure, liver cancer and serious scarring of the liver called cirrhosis. […] Most adults with hepatitis B recover fully, even if their symptoms are bad. Infants and children are more likely to develop a chronic, long-lasting hepatitis B virus infection. […] Symptoms of acute hepatitis B range from mild to serious. The symptoms usually start about 1 to 4 months after you’ve been infected with HBV. But you could notice them as early as two weeks after you’re infected. Some people with acute or chronic hepatitis B may not have any symptoms, especially young children.

  The symptoms of acute hepatitis A infection are identical to those of hepatitis B infection. Early symptoms are headache, nausea, vomiting, abdominal pain, fever, rash, body aches and pains, and dark colored urine. Following this phase, jaundice (yellow-colored skin and whites of the eyes), light stools, and liver pain may appear. […] Both hepatitis A and hepatitis B infection can have immediate, deadly consequences. Approximately 1% of people with acute HBV infections will suffer fulminant hepatitis, or acute liver failure. HAV infection may also, though less commonly than HBV infection, lead to fulminant hepatitis. Up to 90% of patients with fulminant hepatitis will die. […] Up to 95% of adults infected with acute HBV infection recover and do not become chronically (permanently) infected, although they can infect other people during the acute phase via transmission of body secretions. The others become chronically infected and can infect others for a much longer time (in some cases for many years) and are at risk for serious liver disease. The picture is different for children: infants and children who become infected with hepatitis B are much more likely than adults to become chronically infected and hence to develop serious, late complications. […] Chronic infection with HBV may lead to cirrhosis, liver failure, and liver cancer. HAV infection does not lead to chronic infection or chronic liver disease.
