APPLICATION OF A DIFFERENT VACCINE AS A SECOND DOSE
The Strategic Advisory Experts Group, which provides services to WHO, said in a statement last month about vaccines that if this vaccine could not be found after the first dose of AstraZeneca, the Pfizer/BioNTech vaccine could be used as a second dose.
Another clinical trial is ongoing, led by the University of Oxford, focusing on the mixing of the Moderna and Novovax vaccines, as well as AstraZeneca and Pfizer.

In a statement from WHO, “Data from mixing and matching studies of different vaccines are awaited. Both immunogenicity and safety assessment are required.” it was said.
