Scientists say AstraZeneca vaccine has greater effect when it comes to cellular response
A single dose of either the Oxford/AstraZeneca or the Pfizer/BioNTech vaccine generates a big protective antibody response against the coronavirus in people 80 and over, researchers have found.
The first study to look at the comparative performance of the two vaccines that have been in use in the UK in recent months shows that 93% of people develop antibodies against the coronavirus spike protein by five to six weeks after a single Pfizer jab, and 87% after a single AstraZeneca one.
