Did you know there are a number of different Flu vaccines? Till 2012, only a trivalent vaccine was available. It contains 2 Influenza A virus and 1 Influenza B virus. In that year, a quadrivalent vaccine containing 2 Influenza A virus and 2 Influenza B virus was developed. What is the difference between Influenza A and B? In a nutshell, while both causes the flu, Influenza A virus can be spread by both humans and animals while Influenza B virus can only be spread by humans.
In the congested environment we live in today, there has been a rise in cases of Influenza B. Hence for better protection against Influenza B, the quadrivalent Flu vaccine was developed. It is recommended that the quadrivalent vaccine be taken instead of the trivalent one. Even though the initial cost of the quadrivalent vaccine is higher, the greater efficacy and cost savings from reduced infections and hospitalizations far outweigh that.
