There is zero chance of "getting Covid" from any of the vaccines developed, as none of them is "Covid". They only contain the ability to produce the "spike" that the antibodies need to learn about to recognise Covid, not Covid itself.
If anybody tells you that there is a risk of infection from the vaccine, please please respond very, very firmly in the negative. It's fake news like this that dissuades people from getting jabbed.

That's what I thought when I read it. Far more likely they had contracted it just before the vaccine or before it had had time to do the necessary. More worrying was an article in The Times yesterday which referred to boosters required to cope with viral evolution: "We may even need several, grouped in a "quadrivalent" vaccine, like the one for flu. This is when the viral vector approach, even if it does provide durable immunity, hits a problem. What if as well as gaining antibodies against the coronavirus, your body learns to fight the vaccine? If we move to annual boosters then anti-vector immunity may eventually build up to the point when it compromises immunity" (Eleanor Riley, prof. of immunology at the University of Edinburgh). Hopefully, they will have thought of a way to be one step ahead of the virus before that happens. Another Prof. suggests that the choice of vaccine may have to be tailored to the individual, depending on age and immune system, which sounds like a good idea if achievable in due course. A lot to challenge the scientists with.
To be honest, I suspect (based on papers that I've read) that probably the best outcome of the vaccines would actually be if they *don't* stop transmission completely.
I'm not going to go searching for the link again (I posted it earlier today in the one thread or another), but research suggests that immunity gained from actual infection with covid actually develops quite broad antibodies that keep developing over a couple of months, that can even combat other strains.
I've also seen one paper (sorry too late to search for the link now) that suggested the bad outcomes from covid are probably only coming about because it's new. That if the common cold had appeared brand new today, we'd probably be in the same position.
That modelling predicted that once we've gained some initial tolerance, that covid quite likely will just become potentially like the common cold. The suggestion was that ordinarily such tolerance would build up from catching the disease in childhood, to protect when older (the immune system is known to work differently in childhood, and we know children don't seem to be greatly affected by covid infection)
But since it is a new disease, those of us who've already missed that childhood window of opportunity, that's where the vaccines come in.
All the vaccines do seem to protect against the worst effects pretty well. So if people can still catch other variants, but the outcome is mild thanks to the vaccines from the original variants, then in essence the virus will start to act like it's own vaccine (if you see what I mean).
I mean, once you're protected from the worst, there might not then necessarily need to be a race to get vaccines out for every new variant that arise. Or even (hopefully) any new variant.
I think there are good ground to think that perhaps with just a couple of different vaccines each, and perhaps one or two cases of mild disease, moderated by having had the vaccine, quite possibly could confer a reasonably broad level of protection from the worst effects of quite a range of covid variants.
Obviously, this is speculation. But speculation based on some of the emerging evidence and modelling that is being reported.
There was some discussion and worry a bit ago about being given a different vaccine for the first and second dose. To be honest, the more I'm learning and seeing from the research, the more I'm thinking that might now be the option I'd prefer.
