The immunity of those who relapsed and were vaccinated with coronavirus was compared with those who were only vaccinated: the difference in antibodies is impressive

Now she’s confused – should she get a second dose of the vaccine after getting vaccinated and COVID-19? If so, how long must have passed since the illness?

According to koronastop.lrv.lt, if a person has developed coronavirus after the first dose of the COVID-19 vaccine, the second dose is administered no earlier than 180 days after the confirmation of the diagnosis of the COVID-19 disease, unless that the person is not diagnosed with IgG antibodies after the recurrence of COVID-19 disease.

Sick people can only be vaccinated with one dose of the vaccine, which is enough to maintain their acquired immunity. If a resident so wishes, vaccination is also allowed according to the full vaccination schedule, that is, two doses of Comirnaty, Spikevax or Vaxzevria.

As Delfi, the immunologist Dr. Marius Strioga said, if a person has received a single dose and became ill, it is recommended to complete the vaccination and receive a second dose of the vaccine six months after the illness. Surely there won’t be too many antibodies, according to the doctor, especially in terms of strains.

After all, vaccines were developed when there were not so many coronavirus strains in the world. The new strains are more adapted to enter cells and infect them. These antibodies are less effective at fighting strains, they do not bind as well to altered viruses. Their quality is inferior, but this can be compensated by the quantity. Dr. According to M. Strioga: “although less, although not as effective against the varieties, but if there are many, they compensate for everything else.

After relapse, studies show that antibodies are produced in a similar way to a single dose of vaccine. At the same time, if we compare relapse and full vaccination with two doses, there are 10 or even 30 times more antibodies after two doses than after a simple relapse.

However, a person who is sick and still vaccinated has also been found to have much better immunity than one who has been fully vaccinated. Having been sick and vaccinated has about 6 times more antibodies than just being vaccinated.

If I have COVID-19, when can I get vaccinated against this disease?

COVID-19 patients can be vaccinated 150 days after diagnosis. However, a population can be vaccinated earlier if a pre-vaccination antibody test is negative, that is, no IgG antibodies are detected (at least 3 weeks must elapse between the diagnosis of COVID-19 disease and the antibody test) .

Do I need a third dose of the coronavirus vaccine? What to do for those who get vaccinated in winter?

Revaccination decisions are not yet available, they will be based on the results of ongoing clinical trials, the recommendations of the European Medicines Agency and the European Center for Disease Prevention and Control, and the practice of other countries. There are no formal recommendations yet and other countries are in no rush to make national decisions on this.

When is the second dose of the vaccine given?

The timing of the second dose depends on the vaccine:
The second dose of Comirnaty is given 21 days after the first;

The second dose of the Moderna vaccine, 28 days later;

The second dose of Vaxzevria is administered after 12 weeks (the vaccination center may, depending on the individual circumstances of the population, administer a second dose earlier, at 4 to 12 week intervals as recommended by the manufacturer).

Janssen is only given once, so a second dose is not necessary.

If I have COVID-19, when can I get vaccinated against this disease?

COVID-19 patients can be vaccinated 150 days after diagnosis. However, a population can be vaccinated earlier if a pre-vaccination antibody test is negative, that is, no IgG antibodies are detected (at least 3 weeks must elapse between the diagnosis of COVID-19 disease and the antibody test) .
