i thought it was one of the principles of a good vaccine that it not only stopped you getting sick (which these vaccines do ) but it also stopped you getting infected (which these vaccines dont).
with literally 100's of millions of vaccinated people now going to catch covid , doesnt that pose a HUGE risk that , just like the delta became dominant, vaccines resistant covid will become dominant.
is that not the case ??
The vaccines target the spike protein, not the virus itself. They create an immune response where the spikes are rejected from entering your cells.
As I understand it, the successive covid19 strains have been successful at multiplying quicker, but they still use the same mechanism for entering our cells - the spikes of the crown.
There's a limit as to how fast a virus can replicate, based on factors like heat, light, UV, etc. Influenza, for example, doesn't like hot weather so much.
So no, once we've trained our immune systems to resist (the good old "evolutionary blowtorch"), we're on the way.
