I find it funny whenever anti-vaxxers think that literally any adverse effect from a vaccine is concrete evidence of their conspiratorial thinking, as though vaccines haven't already been causing adverse effects and deaths for more than a century. When it comes to viruses and vaccines, science isn't about cheating death or preventing death outright, it's about weighing up which option causes more deaths and going ahead with the one that causes less - in the case of Covid vaccines, significantly less. People who make vaccines are always careful to mention this.
For instance, science established that, in the UK, for every 100,000 people during the pandemic, 114 of them died from Covid. For every 100,000 people who took the vaccine, roughly 1 person has suffered an "adverse effect" (that's anything from death, to a stoke, to an upset stomach). In the US they've confirmed that an average of 0.4 people per 100,000 died after taking the vaccine with a booster (and that's not necessarily to say they died as a result of the vaccine, just that they died after having received it).
So, science looks at the figures. Would it rather 114 people died out of every 100,000, or 0.4 people per 100,000? Science will pick the smaller number of deaths every time. It's cold and objective, but science thinks it's worth sacrificing 1 person out of every 500,000 if it saves the lives of 570 people at the same time (114 x 5).
It should be up to people to make their own choice about whether they get the vaccine. It's why I didn't agree with vaccine passports or ostracising people who decided not to get a booster. As far as I'm concerned, I get my vaccine so other people don't have to. But, by the same token, if people have done the reading and are making an informed decision about their heath and they want to go ahead and get the vaccine, smug anti-vaxxers pointing at literally any medical complaint these days and saying we should get rid of all vaccines and inoculations is pathetic behaviour. Footballers have been collapsing and having heart attacks since way before anyone knew what Covid was.
Funnily enough, Marc Vivien Foe should have been 49 today. Should we track down his family and ask if he was vaxxed when he collapsed and died on the pitch? Thought not.
