So on my way home from school today the radio hosts were talking about the flu vaccine. (Btw this is your reminder to get your flu shot if you haven't already.) The one was like "I never get my flu shot! Never ever ever ever EVER!" like seriously throwing this tantrum over it. Meanwhile the other host was trying to reason like "well you should" etc.
First host says, "My whole family always got their flu shot and a week later they'd get the flu!" Second host says exactly what I'm thinking, that there's an incubation period up to a few days so they probably already had it in their system. First host is like, "Well doesn't it only protect against like 3 or 4 strains? There's like a million flu strains out there." Yes. Yes it does and yes there are. But scientists don't go, "I think we'll do this one, and this one, and this one this year because I'm really feeling this is H1N1's year to shine." How ridiculous. No. They calculate which strains are likely to be the most prevalent each season and put the top 3-4 in vaccines. Plus, that's three or four strains that you're protected against. Like last year when some people said the flu vaccine was like 10-30% effective so they weren't going to bother getting it, that's 10-30% protection you didn't have before.
And then of course their conversation devolved into shots...of alcohol.
TL;DR - Get your flu shot every year.
