My previously very fit and well DP never fully recovered from Covid and died of a coronary thrombosis 7 months after he had it. No previous history of heart issues in the family, so it was a total shock.
I also knew 2 people, also previously in good health, who died of pulmonary embolism within a few months of having Covid.
I know it's anecdata, but it makes me think that vaccinations are probably less of a risk than Covid. I work in a social care environment, so was vaccinated early and have had a booster every year, as have my colleagues. None of us have had any adverse effects from it.
