Because it protects against two subtypes of influenza A viruses and one type of influenza B virus, which is not subtypes

Influenza viruses are characterized by multiple mutations, which enable them to deceive the human immune system,

and usually these mutations occur annually,

and therefore flu vaccines change every year

There are two types of influenza vaccines:

The vaccine prepared from the dead virus, and given by injection

The attenuated virus vaccine - given by nasal spray

The flu vaccine is produced every year, according to the World Health Organization’s forecasts for viruses that are expected to be deadlier than that year

The vaccination is taken at the beginning of the winter season, so it is taken in the beginning of October until the end of November And the vaccination takes effect in approximately two to three weeks
