“Yes, many people have gotten Covid a second time, but it is very rare for someone who had Covid, then got vaccinated, to get Covid again.”
Where are you getting your info from? A recent CNN top article had the headline “Covid reinfection rare, study finds”. So where are you getting this info that “many people” are getting reinfected? There are definitely no articles stating that breakthrough infections after vaccination is rare, because it’s actually very common.
