Over-80s show similar antibody responses following single vaccination with either Pfizer or AstraZeneca vaccine – but cellular responses are
... enhanced after Astrazeneca vaccine.
I heard a snippet on the radio this morning. It's a mystery as to why in this study AZ stimulated a significantly stronger T cell response, compared with Pfizer. I'm mildly encouraged, having booked my second shot of AZ for next week.
The Lancet pre-print is here papers.ssrn.com/sol3/papers...
They use different way of getting the piece of the spike in to active the immune system
Pfizer is an mRNA vaccine - RNA vaccines use only pathogen’s genetic code
The Oxford-AstraZeneca team used a modified version of a chimpanzee adenovirus, known as ChAdOx1
It is being said the the use of adenovirus which is also used in the J&J may be causing the clotting problems
Sure, I know there's a theory that one factor in the unusual blood-clot cases is the adenoviral DNA (there must be at least one rare cofactor or combination). But I'm not aware of any theory linking adenoviral DNA to enhanced T cell response - are you?
Hi zaax,-
I could not get your link to work, and after several tries this one did work for me here in the USA.
