What happens if a person is infected with coronavirus and receives the booster vaccine

Last week, given the escalation in coronavirus cases caused by the Omicron variant, the National Immunization Commission (CoNaIn) recommended to the Ministry of Health postpone the application of the booster dose for 90 days in patients who “are confirmed as cases of covid-19 (symptomatic or asymptomatic) at the time of completing the interval of at least 4 months from the application of the initial scheme”.

But, What happens if a person went to get vaccinated without knowing that they were infected?

“Nothing bad”, he assured in dialogue with Page 12 Jorge Geffner, biochemist and researcher at Conicet. “Why are we not vaccinating and take the space of 3 months? Because the truth would be to waste a vaccine, since the infection itself acts as a very important booster dose. So, in a scenario where there are not enough vaccines, the recommendation is to wait,” he said.

Indeed, “there are many people who were carrying the infection without realizing it and got vaccinated. But absolutely nothing happens“Insisted the specialist.

According to the memorandum from the Ministry of Health published on January 6, the decision to wait a period of 90 days has to do with “the scientific evidence available at the moment on the dynamics of antibody production generated by the disease caused by SARS CoV- 2 and the interference that this could cause in the production of antibodies by vaccination, with the consequent reduction in the expected vaccine effect”.

The “interference” mentioned by the Ministry, Geffner said, “means that With the infection itself, the antibodies will rise 15 to 30 times. And if you add the vaccine, they will not increase your increase, because there is a maximum level of response. So, since it doesn’t add up, the decision is to give it after 3 months. Because after a month and a half, two months, three months, the levels of antibodies begin to drop, although the basic protective immunity lasts, so you have to return to lift them with the additional dose”.

For close contacts of a confirmed patient, meanwhile, the recommendation to postpone vaccination until the end of the isolation period is maintained, to avoid exposing health personnel and people who approach the vaccinators.
