[sorry for quoting the troll]
The same thing the second dose of one of the mRNA vaccines does. It stimulates your memory-B cells to produce antibodies. Other vaccines also use a two dose schedule to confer increased protection.
There is research suggesting that if you've already been infected with Covid, you probably only need one dose of Moderna or Pfizer for good protection. The CDC hasn't changed guidance yet, but it's definitely something that is being looked at. So it's likely that actual covid infection is equivalent to one dose of the vaccine, and does not protect as well on its own (but it likely does offer some protection).
But we have no idea how long immunity last after the MNRa vaccination, no? That’s one of the reasons it’s not FDA approved among others, it’s being studied in real time. Hence the EAU authorization.
So say someone is 35 years old, healthy, healthy weight, no comorbidities, literally almost 0% statistical chance of serious complications from getting Covid.
Can you explain why that person would need the vaccine versus allowing their perfectly functioning immune system to do its job against a Corona Virus?
And since we are talking in “likely” we know that the Covid Vaccine is almost certainly not going to eliminate a Corona Virus but likely be a regular booster shot similar to what is done with the flu each year.
