Flu shot....or not?

Flu [sign in to see URL] not?
Apparently this years flu shot is rather ineffective in preventing people from getting the flu. Doctors and medical researchers have to calculate the nature of the expected flu and develop a vaccine to combat it. Usually they nail it but not this year. Many people refuse to take flu shots at any time because they fear rare but nasty and sometimes deadly side effects and in some states its become a bit of a political issue.
Many parents fear for their children if they take the shot but many more children die every year from the flu rather than the vaccine. The old and the young are most in danger from the flu and often from the vaccine as well. A weak immune system can spell the end for many who catch the flu.
It seems most of us have to decide whether or not we and our kids will take the flu shot or not. Our decision was yes we [sign in to see URL] of us and it has worked out well. What about you and your children or grandchildren? Are you comfortable with the odds of the shot being safe and effective? Or do you stay away from it and wish for the best?}

Re: Flu shot....or not?

There are risks either way.
The medical consensus seems to be the risk of getting the shot is less risk than not getting it.

I haven't read much about it.
From sear's notes:

Influenza only has 8 genes (humans have ~20K).
Two of those 8 genes are responsible for getting the virus into and out of a cell.
Viri enter, or penetrate a cell using the Hemagglutinin gene; referred to as "H". But penetrating the cell isn't enough. After it penetrates and replicates, the replicants need to exit that cell to infect the entire host.
The gene for that is Neuraminidase, N.
In birds, there are 16 different kinds of H gene, and 9 different kinds of N. Every flu is some combination of those.
Humans have only caught a few.
The 1918 influenza virus, H1N1, killed ~50M; ~3% of Earth’s human population.
Hong Kong Flu is H3N2.
Avian flu is H5N1.

But more recently I've read about research being done into finding a vaccine that would vaccinate humans against all possible influenza viri.

That way they wouldn't have to guess which particular flu strain would be circling the globe nearly a year in advance.
