Not to poop in anybody's bowl of corn flakes, and not to say that anyone should or should not get the shot, but there are a few things that you should consider, generally. The production of the vaccine in such a short time should not be that impressive; they do it EVERY year with the flu. They don't even know what particular flu we will have next year, but I'm sure that the vaccine is already being produced for it. It's what they do. Now I am most definately not an anti-vaxer. I believe that the series we get as infants should be mandatory, because those (measles, mumps & rubella, et al) are some truely nasty bugs. But I'm 64, and have not had a flu shot since the early '80's, and have not had the flu since. When I got flu shots prior to that, I always got the flu. Hence, I stopped getting the shot. Many of you may remember back in the military, they used to ransom our paychecks until we got our shot. Then (thank God) direct deposit started and they couldn't use that guise to make me do it anymore.
SO, when my supposed "turn" comes up I'll decide then. I have a wedding to go to in May and will have to fly to attend. If it becomes a requirement to get vaccinated in order to fly, I'll probably do it; but if I get the bug from that shot, I will be angry.
As a small scale rancher, I probably ingest a spoonfull of dirt and whatever per week, thus I'm probably already immune from most of the common bugs. My even getting a cold is an extremely rare occurance. I guess I'm pretty lucky in that account. The funny thing is that people I know who are the most germ-free and are sanitizing everything constantly, are those who seem to get colds and flu every year. Frankly, I'll stick with the spoonfull of dirt.
