I know this is making the rounds of the 'covid vaccine bad'[0] crowd, but isn't it the case that the yearly flu vaccine doesn't guarantee immunity? How has such a vaccine been flying by with such a potential danger present?

- thisiscorrect 5y agoWhat fraction of people take the annual flu vaccine?
- djrogers 5y agoThat’s a pretty straightforward question to find the answer to - it’s just a bit under half, whith kids and seniors being more likely to get it.

- curmudgeon22 5y agoI don't believe it's a matter of 100% guarantee of immunity. The current covid vaccines are designed to prevent severe infection, NOT prevent infection. My understanding is that the current vaccines ~95% efficacy is against severe infection, but we don't actually know what the efficacy against infection is. If you compare this to say smallpox vaccine, it is 95% effective at preventing infections. https://www.health.ny.gov/publications/7022/ https://www.health.ny.gov/publications/7022/
- krona 5y agoThe 95% efficacy statistic was ultimately a positive PCR test, i.e. infection or a 'case' of the disease.
- curmudgeon22 5y agoYes, but only symptomatic folks were tested.
