Most people killed from influenza in a typical season are 65 or older in modern times but influenza in history has killed millions of people.
It takes 2 weeks after vaccination for antibodies to be developed and be effectively immune but...
you could still get the flu after being vaccinated due to a very different strain exposed to your body.
There are two main kinds of vaccine administration 1) A shot of dead microbes in the muscle and 2) A nasal spray of weakened microbes ie. "Live Attenuated"
Generally there are only three strains of Flu in a vaccine per season and are decided by the CDC months ahead of Flu Season on what statistically might be the most prevalent
The "Stomach Flu" is not a type of influenza but is usually attributed to a different cause
Should you get a Flu shot? Well it wont kill you and know it wont give you any side effects like autism, that is just a myth
