It's more effective than most vaccines, but most vaccines are for relatively rare diseases (due to near-universal vaccination for decades). The pertussis vaccine is only about 80% effective against contracting pertussis, but, nearly nobody is exposed to pertussis EVER, versus nearly everyone being exposed to the flu (or to covid) -- usually several times.
- Zababa 5y agoThat might be me being misinformed about them, but when I think about vaccines I think about think like polio and how they almost don't exist anymore.
- freeone3000 5y agoDue to universal administration over years. The polio vaccine is particularly an awful one, with only about 90% effectiveness (matching the covid vaccine) but the ability to cause polio as a side effect. Polio is nearly eradicated because so many people got the vaccine. It only works if everyone does it.
