html On May 20, the Joint Prevention and Control Mechanism of the State Council held a press conference to introduce the situation of epidemic prevention and control and vaccination.
A reporter asked: Recently, some members of the public reported that when two doses of COVID-19 vaccines were administered, they were found to belong to different manufacturers. Will "mixed doses" affect the vaccination efficiency? Under what circumstances is it possible to fight in a mixed manner, and under what circumstances is it not allowed?
In this regard, Shao Yiming, a researcher at the Chinese Center for Disease Control and Prevention, said that situations like this usually occur only when vaccines of the same type and with the same technical route are used.
"The main reason may be that the supply of the vaccine is not in place at the moment. We have done a lot of scientific research trials before. In this case, using a vaccine with the same technical route from another manufacturer will have exactly the same effect. It will not affect the protective effect, but will not affect the safety of the vaccine."
He said that our country and the international community have also seen that some research data has emerged, and vaccines with different technical routes are also being "mixed", which is a real "mixed approach." The purpose of this "mixed fight" is to induce a stronger and longer-lasting immune response.
"However, this has not yet been reviewed and determined as a new immune strategy by the drug regulatory department, and is still in the stage of data accumulation. We have also been paying attention, including our country, which is also conducting research in this area."
