Human Response
- Immune Response: According to clinical trials, there were high levels of antibodies in 97.5% of those vaccinated after a single dose of Proquad (FDA: ProQuad).
- Side Effects: Side effects of vaccination include: injection site reactions, fever, irritability and diarrhea.
|
Human Response
- Immune Response: Clinical trials with several formulations of VARIVAX containing the attenuated virus ranging from 1000 to 50,000 PFU per dose, have demonstrated that VARIVAX induces detectable immune responses and is generally well tolerated in healthy individuals ranging from 12 months to 55 years of age. VARIVAX was also found to induce cell-mediated immune responses in vaccinees (FDA: Varivax).
- Side Effects: Side effects of vaccination were mostly injection site redness and pain.
- Efficacy: The majority of subjects who received the vaccine and were exposed to wild-type virus were either completely protected from chickenpox or developed a milder form of the disease. Clinical studies have demonstrated continued protection up to 10 years after vaccination. Also, a boost in antibody levels has been observed in vaccinees following exposure to wild-type varicella as well as following a second dose of the vaccine (FDA: Varivax).

Human Response
- Side Effects: The most common side effects reported included headache and injection site reactions (FDA: Zostavax).
- Efficacy: According to clinical studies, ZOSTAVAX significantly reduced the risk of developing zoster when compared with placebo. Vaccine efficacy for the prevention of herpes-zoster (HZ) was highest for those subjects 60-69
years of age and declined with increasing age (FDA: Zostavax).
