Je neúčinná voči niektorým mutaciam
viaceri tu pisete, ze Astra je voci niektorym mutaciam neucinna v porovnani s Pfizerom... dajte mi pls odkial to mate?
Lebo ja evidujem tuto info:
Will vaccines still work against variants?
Current vaccines were designed around earlier versions of coronavirus, but scientists believe they should still work, although perhaps not quite as well.
A recent study suggests the Brazilian variant may be resisting antibodies in people who've already had Covid and should have some immunity.
However, early lab results and real life data suggest the
Pfizer vaccine can protect against the new variants, although slightly less effectively.
Data from the Oxford-
AstraZeneca vaccine team suggests it protects just as well against the new UK variant.
It offers less protection against the South Africa variant - but should still protect against severe illness.
Early results suggest the Moderna vaccine is effective against the South Africa variant, although the immune response may not be as strong or long-lasting.
Two new coronavirus vaccines awaiting approval - Novavax and Janssen - also appear to offer some variant protection.
Experts say with a new virus mutation, even in a worst case scenario, vaccines could be redesigned and tweaked in weeks or months to be better matches.
The UK Government has announced a deal with biopharmaceutical company CureVac to develop vaccines against future variants, with a 50 million dose pre-order.
