Are you confused like I am? We hear that the Covid-19 vaccine is a wonder drug that will "save us all", then we hear that it has only a 66% efficacy. That doesn't sound that good to me. What is really going on here? Is the vaccine something I should get, or just a waste of time, money, and effort? Here is the good news.
We are being confused by semantics.
- To me, I use "effective" to mean whether something will work at all, but this is not how scientists are using the term. To them it means how well the drug can prevent you from getting any symptom of the illness.
- All I care about is living and not being damaged permanently by the covid-19 virus. That is very "effective" to me. All our covid-19 vaccines are very "effective" in this way.
