Playing with fire.
Initially, it was thought that if you got Covid-19, natural immunity lasted 2-3 months. Now studies show maybe up to 11 months. However, about 36% people who got Covid didn't develop the antibodies (natural immunity).
I'd wait to see more data on this. Getting the vaccine (and booster) seems to the safer route. But intentionally getting Covid-19 after vaccination seems crazy.
PS. I get the flu shot every year but don't go looking to get the flu and get sick.
