  The rationale for PEP in pregnant women is two-fold: reduction in severity of maternal disease and theoretical reduction in the risk of fetal infection for women contracting varicella in the first 20 weeks of pregnancy. […] In light of the existing evidence on the safety of aciclovir, the efficacy of aciclovir in preventing clinical chickenpox in healthy and immunosuppressed contacts, equivalence of antivirals as PEP and that VZIG is no longer available, antivirals are now the treatment of choice for exposure to varicella or shingles for susceptible women exposed in any stage of pregnancy. […] Post-exposure prophylaxis is recommended for: Group 1 – Neonates whose mothers develop chickenpox (but not shingles) in the period 7 days before to 7 days after delivery: VZV IgG antibody testing of the neonate or mother is not needed. Varitect (intravenous varicella immunoglobulin) or IVIG should be started as soon as possible and preferably within 7 days of exposure.

  For people with HIV who are susceptible to VZV, post-exposure prophylaxis following known or suspected VZV exposure is recommended (AII). […] After close contact with a person who has active varicella or herpes zoster, adolescents and adults with HIV who are susceptible to VZV (particularly those with CD4 counts 200 cells/mm3) should receive VariZIG as soon as possible (preferably within 96 hours), but up to 10 days after exposure (AIII). […] Given the cost of obtaining VariZIG, it is reasonable to check VZV serology before administering VariZIG to people who do not have a clinical history of chickenpox or shingles and no documentation of varicella vaccination (AIII). […] The risk of VZV transmission is greater with exposure to varicella than localized herpes zoster. […] Long-term prophylaxis with anti-VZV drugs, such as acyclovir or valacyclovir, to prevent varicella is not recommended (AIII).

  Long-term administration of anti-VZV drugs to individuals with HIV to prevent episodes of herpes zoster is not routinely recommended (AII). […] However, in a randomized, placebo-controlled study in Africa that evaluated daily acyclovir prophylaxis (acyclovir 400 mg orally [PO] twice a day) administered to people with HIV/HSV-2 coinfection who were not taking ART, acyclovir prophylaxis reduced the rate of herpes zoster by 62%. […] Acyclovir did not prevent recurrent zoster episodes in patients with prior history of herpes zoster. […] People with HIV who are taking suppressive anti-herpes medications (i.e., acyclovir, valacyclovir, or famciclovir) for other indications such as prevention of genital herpes may receive some additional benefit in reduction of risk of herpes zoster, but the relative risk reduction in people who are receiving ART is unknown.
