650K people die from flu each year according to the World Health Organization. Vaccination (herd immunity) is especially important to protect people at highest risk. Even pregnant women need one according to the CDC and Consumer Reports.
Consumer Reports also addresses the three common excuses for not getting the flu shot in their article “Why Your Excuses for Not Getting a Flu Shot Stink“. Up front is the idea that it can cause the flu. No, it just makes your symptoms less severe if you get it (e.g. YOUR LESS LIKELY TO DIE… dying being a symptom apparently). And no, there is no scientific link to autism despite tons of fake news to the contrary.
So please, do the world a favor and get a flu vaccination yearly.
