b. Antibiotic-free formulation
A distinguishing feature compared to most currently available varicella vaccines.
Manufactured in accordance with FDA Aseptic Processing standards.

Thanks to improved manufacturing processes, the minimum viral potency is maintained at ≥ 3,800 PFU, ensuring vaccine stability throughout its product lifecycle.
d. Cost-effective pricing to support expanded immunization coverage
BARYCELA is competitively priced, enabling vaccination providers to more easily expand services across diverse population groups. Affordable pricing encourages earlier vaccination in children, thereby increasing vaccine coverage, reducing outbreak risk, and lowering treatment burdens within the community.
6. Disease Burden and Complications of Varicella
According to data from the CDC and WHO, varicella is often mild but may cause serious complications even in otherwise healthy children, particularly in school settings.
Reported complications include:
- Skin and soft tissue infections (impetigo, cellulitis, abscesses)
- Acute cerebellitis, resulting in tremors and ataxia
- Encephalitis and meningitis
- Varicella pneumonia
- Permanent scarring due to extensive skin lesions
- Secondary attack rates of up to 80–90% among non-immune individuals
Vaccination remains the most effective intervention to reduce disease incidence, prevent complications, and limit outbreaks in schools and communities.
