DDs partner had Covid last May, so possibly the A virus and was very ill, he is now fully vaccinated but was ill again in December, not as bad but he is still feeling the after effects.
He teaches at a boarding school with many foreign pupils, plus U.K. pupils holidaying abroad, but he doesn’t know if the latest virus was D or the latest Omicron variant, (either way he is fed up with it) who know which Countries have which variation by now?
But it seems that for some people there is no immunity from any of them.
So,IMO I think that we still at risk from all of the variants and whether or not you have any underlying health issues will decide the outcome for you.
As we both have health problems we are still being careful and it’s getting a tad tedious, although we are venturing out for a curry tonight….whoop de dooo.
