Lots of good info for those who already been infected and vaccine shy:

"A prior infection offers protection in the range of 80%, compared to about 95% for the Moderna and Pfizer vaccines, said Dr. John Wherry, director of the Institute for Immunology at the Perelman School of Medicine at the University of Pennsylvania. That means about 15 to 20 out of every 100 people who have previously had COVID-19 could get reinfected, while 5 out of every 100 people who got an mRNA vaccine might get infected."
"People with more severe infections appear to have stronger antibody responses than those who had milder or asymptomatic infections, Maragakis said. In addition, she said, the status of a person’s immune system can also dictate the quantity of antibodies and the quality of their antibody response. "
Lab studies suggest that protection following a case of COVID-19 begins to wane slightly after about three months, but can last for up to 10 months, although there’s a range to that, Wherry said."
------------------------
TL;DR: There is a wild range of immunity after already being infected, what also wanes over time.
Covid will be with us for years. It is easier to get a vaccine annually (that eventually will be tweeked for the most dangerous variant), than getting your antibody level checked in every few months. If it eventually drops let's say to 40-30%, you will want to get the shot anyway, so why don't get it now and chill?
