According to an infectologist, immunization does not guarantee, however, that the vaccinee cannot transmit the virus to other people, which justifies the maintenance of sanitary measures.
Brazil has so far had at least 4.5 million people vaccinated against coronavirus. They are health professionals, elderly and indigenous people who received doses of CoronaVac and Oxford-Astrazeneca. But only a small portion of that group can say that it is actually immunized. The reason is that the body begins to produce antibodies against Covid-19 just fifteen days after the second injection, as infectologist Renato Kfouri explains. “That protection promised in studies of vaccine efficacy will only be obtained 15 days after the second dose,” he said. Regardless of whether or not you are immunized against the coronavirus, the truth is that it will not be possible to abandon the masks anytime soon, since after receiving your doses the person is less likely to get sick with Covid-19, but she still can be a carrier of the disease.
“A vaccine it does not prevent you from contacting the virus, from acquiring the virus and transmitting the virus. It will prevent him from getting sick and getting seriously ill, ”said the infectologist. Although science has a lot of information about Covid-19, some questions remain unanswered. It is not known, for example, how long a vaccinated person is immune to the disease and how often vaccines will need to be applied, as several mutations of the coronavirus are being discovered.
