About
About vaccine
- It is funded by the Coalition for Epidemic Preparedness Innovations (CEPI) with support from the Ind-CEPI mission of the Department of Biotechnology (DBT),
- The development of the Chikungunya Vaccine is an initiative of the United Nations Development Programme (UNDP), as part of the Global Chikungunya Vaccine Clinical Development Program (GCCDP).
- The vaccine is named BBV87 and going through a controlled trial to evaluate the safety and immunogenicity of a 2-dose regimen in healthy adults across five countries with endemic Chikungunya.
- Inactivated whole virion:
- BBV87 vaccine is an inactivated whole virion vaccine based on a strain derived from an East, Central and South African genotype.
- Inactivated vaccines contain viruses whose genetic material has been destroyed by heat, chemicals or radiation so they cannot infect cells and replicate.
- Inactivated virions technology has a safety profile that potentially makes this vaccine accessible to special populations, such as the immuno compromised and pregnant women that some other technologies cannot reach.
- BBV87 vaccine is an inactivated whole virion vaccine based on a strain derived from an East, Central and South African genotype.
