over four hundred thousand adverse reactions
Citation? bear in mind that, as previously explained, reports of adverse reactions are not necessarily vaccination-related, and - as seen with other drugs - on statistical analysis, the vast majority reported through the Yellow Card system and the Vaccine Adverse Event Reporting System (VAERS) turn out not to be related.
Meanwhile, at least 5 million Covid deaths have been reported, which, given the known under-reporting in major populations (e.g. India, Africa, Russia) is likely to be a substantial underestimate of the total (some sources think the India toll may be up to 10 times higher than government figures).
But taking the figures at face value gives a one in 16,500 chance of some kind of adverse reaction to the vaccine (jabs 6.6 billion / reported adverse reactions 0.4 million), against a best case of one in 1,600 chance of dying from Covid (world population 8 billion / reported deaths 5 million, ignoring the fully vaccinated).
So, very crudely, in a worst-case comparison for the jab, you're still an order of magnitude more likely to die of Covid than to get an adverse reaction to the vaccine.
