In a first, WHO recommends quadrivalent influenza vaccine

Sanofi Pasteur’s injectable influenza vaccine containing two A virus strains and two B virus strains for active immunisation of adults of age 18 to 64 years was approved in 2017 by Drug Controller General of India (DCGI). The application for the paediatric indication is under review by the DCGI. Final approval is expected by the end of month of June.

Sanofi’s quadrivalent influenza vaccine was licensed for use by the US Food and Drug Administration (FDA) in 2013. It is licensed in 26 countries.

What is quadrivalent flu vaccine?

The quadrivalent flu vaccine is designed to protect against four different flu viruses; two influenza A viruses and two influenza B viruses.

Why was quadrivalent flu vaccine developed?

For years, flu vaccines were designed to protect against three different flu viruses (trivalent). Trivalent vaccines include an influenza A (H1N1) virus, an influenza A (H3N2) virus and one influenza B virus. Experts had to choose one B virus, even though there are two different lineages of B viruses that both circulate during most seasons. This meant the vaccine did not protect against the group of B viruses not included in the vaccine. Adding another B virus to the vaccine aims to give broader protection against circulating flu viruses.

Case in India

  • More than 115,000 cases of influenza and more than 8,000 deaths due to influenza have been recorded since 2010, according to the ministry of health’s Integrated Disease Surveillance Project (IDSP).
  • However, this number is limited to influenza caused due to one strain, H1N1, only. 
  • The experts also noted that in 2017, the H3N2 and B subtypes of influenza virus were circulating, due to a build-up of the susceptible population.
  • It was the first time the team had documented circulation of H3N2 and Influenza B.
