It may very well be that it helps. Well, that is, people did not feel well after undergoing covid, then they were vaccinated against a new coronavirus infection, and they felt better.
Covid can drag on, and it is completely unclear what to do with it at this stage. Months pass after discharge, and the victims continue to break, weakness rolls over, everything hurts, work capacity is low, shortness of breath does not allow to move. This is the lingering covid.
If such a person is vaccinated against the coronavirus, then sometimes for some reason all his ailments go away. This is strange, because the vaccine itself is unbalanced and few people like it. There are two explanations.
Remnants of the virus
It is suspected that after recovering from covid, not all viruses die, but for some time they live in the body of the patient. But they don't just sit inside, but slowly poison his life. The vaccine kicks up the immune system, and it finishes off the remains of the covid. It gets better immediately.
Evil immunity
Here is the opposite situation. During covid, the immune system becomes so wild that it cannot calm down for a long time. Even after recovery, he constantly sees coronaviruses, which he is trying to look for in various organs and parts of the body. People get sick from this. But after vaccination, the immunity directs all its aggression to the vaccine, and it immediately becomes easier for a person.
How good or bad is it
It is believed that vaccination helps 30-40% of people with lingering covid.
And it would be wonderful if 10-15% of those vaccinated didn't get worse. That is, it is a lottery, but with good odds. On average, it is generally accepted that the vaccine does not get any worse.
So is it necessary to vaccinate those who have been ill?
Of course you do! People get sick two or three times. If you do not get vaccinated, then the second or third covid can finish you off.
