It pointed out that mixing biologics as a booster -regardless of the laboratory that developed them-, has the objective of returning people to the level of immunization they had achieved in the first round.

Association Coordinator Rodrigo Romero Feregrino explained that mixing vaccines as a booster ensures that people regain the immunization level they had achieved with the two previous doses so as not to become seriously ill and avoid dying if they become infected.

In this case, immunity is achieved immediately after the third dose because there was already protection with the previous scheme.

The WHO, he added, recommends that people who were immunized with Sinovac or Sinopharm, for example, should be given another vaccine after six months, and if there is no vaccine available, they should be given the one that is in stock.

Both the WHO and the Food and Drug Administration of the United States and the European Medicines Agency are considering that another vaccine can be administered safely because there are already several studies that have shown that it does not cause any harm and they are looking at which combination creates the best response.
