The vaccine does prevent the severity of Covid and reduces instances of death. I mentioned earlier, what will be the capacity of your lungs after 3+ bouts of Covid. It's an honest question because Covid is here to stay, it's very contagious and chances are everyone will get it at some point. It's no longer "If I get it". You may not get it this year or next year.......But, It's coming.

Is COVID-19 lung damage reversible?
After a serious case of COVID-19, a patient’s lungs can recover, but not overnight. “Recovery from lung damage takes time,” Galiatsatos says. “There’s the initial injury to the lungs, followed by scarring. Over time, the tissue heals, but it can take three months to a year or more for a person’s lung function to return to pre-COVID-19 levels.
“Lung healing in of itself can produce symptoms,” Galiatsatos says. “It is similar to a leg bone breaking, needing a cast for months, and having the cast come off. No one would expect to begin to run right away with the newly-healed leg bone. As the leg strengthens and muscle re-grows, patients will experience discomfort from this healing. This is what our lungs go through, too!”
