OAZ: no reaction at all.
Pfizer on my wife: first jab: swelling, soreness & reddening at the jab site that lasted a few days; second jab, no issues whatsoever.
My elder brother is a retired dentist and a volunteer vaccinator. He’s jabbed thousands of people. He tells me that the official line, borne out by discussions with those having a second jab, is that side effects of both vaccines have been significantly less than expected. He had joint pains for a few weeks, which is apparently very common.
My brother is also pretty sceptical of a problem with blood clots. The data he has access to indicates that overall they are no more common than would be expected from a population of the ages vaccinated and, if anything, are actually lower. Apparently, 20% of hospital Covid patients have blood clots so an issue is hardly surprising. He thinks the odds of blood clots after a vaccine are much lower than with Covid without vaccination even for the very young.
