eenie, I’m in medical school. You’re somewhat right to be skeptic about flu shots because regions spend lots of money on vaccines that don’t provide full coverage/efficacy— they don’t cover every strain, and sometimes the shots have a year where they’re particularly ineffective. So from an economical standpoint, there’s a critique where maybe we should only be giving these shots to at risk populations, like the elderly & the children.

In terms of science and safety though, I am promising you— there’s no harm.
one other point— flu shots and their varying efficacy are *not* the same as the MMR, or the dTap, or the HBV, or the HPV vaccines— these vaccines are insanely effective, and the main reason why their respective diseases have gone down in number. Their purported complications have been disproven— I’ve read through it all.
please, get vaccinated for these more significant ones if you’re not already. If you never take another flu shot again, I don’t give a ****.
