Convalescent vaccinations against COVID-19 are more effective

Research shows that vaccination against COVID-19 is more effective in convalescence than in those without a history of infection. People who have not been infected with the Coronavirus need two doses to “feel safe”, while patients receive protection after the first dose.

A study conducted by the INVICTA Research and Development Center in Poland showed that among people without a history of infection with the Coronavirus, the average level of antibodies within 14 days of the first dose of the vaccine was 60.99 units / ml, and shortly before the second dose of the vaccine (usually 21 days after the first dose) increased by 122.83 units / ml.

Meanwhile, the injured were injured SARS-CoV-2, before vaccination, had already obtained results with an average level of 54.94 units / ml, and 14 days after the first dose, the observed antibody level exceeded 2,500 units / ml (out of 86% of respondents).

The first group (with no history of infection) required a second dose of the vaccine to reach this antibody level. Of those, 71%. I reached antibody levels higher than 2,500 units / ml on the eighth day after the second dose of the vaccine.

A single dose vaccine for convalescence?

The results of the study probably indicate that In people who have been infected with SARS-CoV-2, one dose of the vaccine is sufficient to achieve the same effect as it does in people who have not previously come into contact after two doses..

Similar conclusions were made by Dr. Paweł Grzesiowski, MD, expert of the Supreme Medical Council for COVID-19 Control:

Research shows that people in convalescence respond better to vaccination than those who have not had COVID-19; Maybe a single dose of J&J vaccine should be suggested to convalescence first? – Dr. wrote on Twitter. Grzesiowski. In his opinion, after vaccination, you can measure antibodies and only then make a decision.

– Most of the survivors are vaccinated after 3 months, because they have immunity after the disease, which prevents them from infection again – and avoids the interference of postpartum complications with the vaccination – confirms the expert of the Supreme Medical Council. The exception, he adds, is people who do not have immunity after their illness (they lack anti-S antibodies in the blood).

Dr. Bowie Grzysovsky also notes that researchers have identified more than 300 human proteins that bind to the coronavirus during active infection. Many of it protect our cells from dying, but the virus’s RNA, for example, can lower levels of the proteins NHE3 and DRA, which are responsible for absorbing water in the gut. This results in diarrhea that occurs in some infected people.

Earlier, we wrote that the French Health Authority was recommending that convalescents receive only one dose of the COVID-19 vaccine. France is the first country to offer such advice.
