“People who recovered from Covid do not need the vaccine”
Maybe if they had sufficient antibodies the argument might make some sense. Just because someone had covid in the past does not make them immune, there are a lot of people that got covid twice.
Getting Covid twice is rare.
Based on your argument (not mine), you shouldn’t vaccinated since people can get Covid despite being vaccinated.
For those rare cases of getting Covid a second time (or a first time after vaccinating), the symptoms are very rarely severe.
Indeed, European countries accept proof of having recovered from Covid as a basis to not vaccinate and still be permitted in places where otherwise only vaccinated people are permitted.
America refuses to do that only for political reasons.
