Studies on the combined use of the AstraZeneca and Pfizer / BioNTech vaccines have been done for some time. I suppose colleagues have some observations of what is happening. The US Centers for Disease Control said it allows, in exceptional circumstances, when a second dose of an RNA vaccine cannot be provided, another RNA vaccine can be administered. Pfizer / BioNTech and Moderna will be combined. This is not something new.
This was stated in Nova News by the BAS virologist, Prof. Radostina Alexandrova.
“The stipulation is that the best option is to do what has been shown to work during clinical trials and has been approved by institutions,” he added.
“Combined studies are being carried out, on the one hand, between AstraZeneca and Sputnik V and, on the other, between AstraZeneca and Pfizer / BioNTech. They also monitor the immune response in people who are vaccinated, precisely to obtain information as quickly as possible. However, this is a decision that is made under the pressure of circumstances, “said Professor Alexandrova.
According to her, the big bet is to restore people’s trust in both vaccines and drugs.
