Hello; I have been paying some attention and so far the information I find is those naturally recovered still have the immune response from the infection. This will be an ongoing thing in the sense of time passing. But so far week by week and month by month the naturally recovered are being found to maintain an immune response. At least this is what the most recent information has been I have seen.That is contradictory to CDC guidance:
If I have already had COVID-19 and recovered, do I still need to get vaccinated with a aCOVD-19 vaccine?
Yes, you should be vaccinated regardless of whether you already had COVID-19. That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19
I imagine the experts who do not yet know how long a natural immunity will last will let us know when they have some definite information. I imagine the thinking of those who are recovered may be why risk any potential side effects of a vaccine as I am already naturally protected. Anyway here is a good place to show the evidence the naturally recovered are losing that acquired immunity if you have it.
