And what about people that had COVID and recovered, is there any reason for them to be vaccinated?

Yes on 2 counts.

Unknown how long B/T cell protection lasts after recovery from infection. Recommended currently is they get 1 jab, and not 2. The mRNAs are generating Ab responses sky high relative to those who have recovered from infection.

There are cases where they recovered from the original wildtype strain, and then came down with a severe case from the B.1.351 strain.

If one is an asymptomatic carrier, recovered from an infection without knowing it, then a vaccine might help, taking out the low level of virus, and eliminating them as a carrier. The fun part is whether a vaccinated person can become a carrier, when coming into contact with the virus. With the virus staying localized in the nasal passages. Thus, the vaccinated being told to keep wearing masks around the non-vaccinated. Until more data comes in.

There is a test to see if you previously had a mild case of Covid and you now have the antibodies in your system to fight off a reinfection.

And what about people that had COVID and recovered, is there any reason for them to be vaccinated?

Yes and no and maybe. Yes for people over 65. No for people within the 6 month window. Maybe because the second bout will be mild.

From the NYT this morning.

Coronavirus Reinfections Are Rare, Danish Researchers Report
People over 65 are more likely to experience a second bout with the virus, according to a large study of medical records.

The vast majority of people who recover from Covid-19 remain shielded from the virus for at least six months, researchers reported on Wednesday in a large study from Denmark.

Prior infection with the coronavirus reduced the chances of a second bout by about 80 percent in people under 65, but only by about half in those older than 65. But those results, published in the journal Lancet, were tempered by many caveats.

...

Scientists have said that reinfections are likely to be asymptomatic or mild because the immune system will suppress the virus before it can do much damage. The researchers also did not assess the possibility of reinfection with newer variants of the virus.

Still, the study suggests that immunity to a natural infection is unpredictable and uneven, and it underscores the importance of vaccinating everyone — especially older people, experts said.

Wouldn’t it make sense to then test those people for immunity and then take them off the list for vaccination?

Not at all. Those people can still spread it.

And what about people that had COVID and recovered, is there any reason for them to be vaccinated?

Yes. It seems their immunity is fairly short-lived.
