What is the issue ?
- In February 2018, for the first time, the WHO issued an official recommendation for a quadrivalent vaccine.
What is a quadrivalent vaccine and how is it different from a trivalent vaccine ?
- While a trivalent influenza vaccine contains both A subtype viruses, it has only one of the B subtype virus, the quadrivalent vaccine offers greater breadth of protection as it includes both B subtype viruses.
- Since a quadrivalent magazine offers a greater breadth of protection against influenza virus, it is increasingly being preferred to in place of trivalent ones.
- The quadrivalent vaccine will contain four influenza virus strains (two A subtypes and two B subtypes — H1N1 and H3N2, and Victoria and Yamagata respectively).
Qaudrivalent vaccine in India :
- Sanofi Pasteur’s injectable influenza vaccine (FluQuadri) containing two A virus strains, H1N1 and H3N2, and two B virus strains, Victoria and Yamagata, for active immunisation of adults of age 18 to 64 years was approved in May last year by the Drug Controller General of India (DCGI). Final approval is expected by the end of June 2018.
