I just got my flu shot; ladysolly did too. She mingles with a lot more people, via her bridge activities, than I do
I did this for several reasons.
1) The Lurgi I got last May wasn't flu, but it was bad enough, and I suspect flu might be worse.
2) It's recommended for people as ancient as me
3) Also for people with Asthma
4) And bronchitis
But the most convincing reason, is provided by the "anti vaxxers", the people who are so opposed to vaccination that they won't get jabbed, or let their kids get protected. And I sneer at such people, and would argue with one if they ever showed their face to me. And then I thought, I should use all those arguments on myself.
I got vaccinated, not only for myself, but also for all those people who won't, or can't.
