István Vályi-Nagy, director of the South Pest Central Hospital – National Institute of Hematology and Infectious Diseases (DPC), told the article that it was very important to study the course of the immune response over time, since vaccines must provide the minus a similar level of protection.
He also mentioned that 60-70 percent of the population must be protected for the immunity of the flock to develop. On the newspaper’s question, he confirmed: the part of the population that has already been infected may not need to be vaccinated, and the later the vaccine arrives, the greater the proportion of this group in the total population.
István Vályi-Nagy also spoke about the fact that the real protection will be created by an original vaccine and, in the case of some vaccines, a booster dose given two or three weeks later, 15-20 days after the second dose, because it will be very long. Protective immunoglobulins need to be available in the blood.
István Vályi-Nagy said that the DPC and the NNK will monitor those vaccinated. He also reported that plasma donors registered in the first wave would also be included in the investigation to see if there were still antibodies and cellular immunity in the bodies of those who had previously recovered from infection.
In parallel, the effect of the vaccine and the immunity of patients who have recovered from the infection are being studied, because it is not yet known how long the latter will last, said the hospital manager.
