From what I’ve read recently, Covid vaccines are quite batch variable. Some batches have apparently caused excess adverse reactions have been withdrawn in the past. Just because someone has had one, two four or more Covid vaccinations without apparent complications doesn’t mean this will continue. Then of course there is time. It could be Jacob that you’ll have a stroke or heart attack in a few years but no one will attribute it to your vaccinations. Because quite simply you’re unimportant and it’s not in their interest.
