British study: Mix more effective than two AstraZeneca shots
But new studies show that combining two different vaccines could be more than just an emergency solution.
Researchers at the University of Oxford have found that patients who received a dose of AstraZeneca followed by a dose of the BioNTech-Pfizer vaccine four weeks later developed a higher number of antibodies than those who had received two shots of AstraZeneca.
As part of their Com-COV trial, the Oxford researchers administered various vaccine combinations to 830 volunteers over the age of 50. Their results showed the highest number of antibodies was developed by people who had received two BioNTech jabs, followed by those who had gotten a shot of AstraZeneca first and BioNTech second. The reverse order still yielded more antibodies on average than two shots of AstraZeneca. "
