4. Actually, if you got Influenza A in 2019 you have a very strong immunity

to future influenza A that will probably last decades.

The reason most people over the age of 50 in 1918 never got that flu was that about 50 years earlier there was an outbreak of a similar type A flu. Those alive then got it and died, or survived, or were somehow already immune/resistant to the flu.

So go ahead and get a shot if you want, but it's probably not necessary.
