Chickenpox (Varicella) Vaccines
Chickenpox, or Varicella, is a highly contagious viral infection caused by the Varicella zoster virus (VZV). While often mild in children, it can lead to severe complications in adults, pregnant women, and immunocompromised individuals—including pneumonia, skin infections, and hospital confinement.
Vaccination provides safe, long-lasting protection against varicella and helps reduce transmission in workplaces, schools, and households.
Affinity Vaccines offers FDA-approved Chickenpox Vaccines from trusted global manufacturers: Varilrix® (GSK) and Varivax® (Merck Sharp & Dohme). These vaccines are suitable for both adult and pediatric immunization and are administered by licensed healthcare professionals under strict cold-chain protocols.
