That's a tricky one. Since the evidence they have indicates that it does little to protect against the SA strain, suspending use presumably means they still go forward with using other vaccines. You don't want people walking around thinking they have protection if they don't, particularly if there are other options.tallyho wrote: ↑2 weeks ago Don't understand the SA position of suspending Astazeneca jabs as they don't seem as effective against the SA strain. It protects against the normal virus which is still prevalent in SA and lessens the impact of the stronger strains so its still hot to be better than nothing.
On a broader level, until infection numbers around the world are far, far lower than they are now, new strains will continue to appear. Presumably the vaccines can be tweaked to protect against new strains, but that takes time. We still need to be on high alert until infection numbers are way lower, which will happen as vaccine use proliferates.
