The effects that contamination by the new coronavirus can have on the human body continue to be studied every day. The different responses that each organism presents after confirming the diagnosis, such as the presence or absence of symptoms, confirm that there is no universal rule on how the pathogen will interfere with the health of each individual.

As with some other diseases, such as chicken pox, some patients recovered from COVID-19 believe that they are already immunized and, consequently, do not need to be vaccinated. But what is the difference between the immunization that occurs with the infection and the one that comes with the vaccine?

According to Matheus Todt, an infectious disease doctor at SOS Vida, the immunity acquired by the infection exists, but it is temporary. “It is believed that it can last for a few months. Vaccination allows for more lasting protection. Therefore, the vaccine should also be taken by people who have had COVID-19“, Explain.

Still according to the expert, the number of doses of the vaccine does not differ between those who have already been infected and those who have never received a positive diagnosis of coronavirus. “All vaccine protocols that we have today provide for the same amount of doses (usually two doses at intervals of a few weeks) for everyone”, explains Matheus.

Antibodies and COVID-19

Among the tests that can diagnose a coronavirus case is the serology test. Done through blood analysis, this testing determines whether the body has produced IgG and IgM antibodies.

IgG and IgM are classes of antibodies (defense molecules), produced by the body specifically against a certain antigen – a foreign substance to the body, which can be a virus, bacteria or toxin.

Some cases have already been reported of patients who had a positive diagnosis of the disease and, when performing the serology exam, it was pointed out that the production of antibodies against the SARS-CoV-2 proteins was considered low or even non-existent.

In addition, recent research by Stanford University in the United States has revealed that immunity caused by coronavirus infection may be short-lived, disappearing after the fourth week of treatment against the disease.

Therefore, experts say that vaccination should take place even after confirmation that antibodies have been produced in the serology test.
