I'll repeat what I posted in the other thread:
Let's look at the two vaccines the US has now agreed to authorize for emergency use. Both are about "95% effective". That means, about one in 20 people who gets them will still get COVID if exposed.
Most scientists are now saying they believe the vaccine-induced immunity is actually better (more effective) than natural immunity you would get from having the illness (because it's more specific to the virus's most important vulnerability, the spike protein).
That means likely more than 1 in 20 people who have had COVID will, if re-exposed, "get it again". But looking at it from a the half-full viewpoint, 19 people (or maybe slightly fewer) who've had it won't get it again even if they are exposed.
