Sorry, this probably isn't what you want to hear ... she should prepare for a worse reaction with jab 2.
I would prefer to hear it straight. Thank you for being honest.
Having just read the news about AstraZeneca, blood clots, one dead in Italy and other countries stopping using the AstraZeneca vaccine I have a clue what might have increased the fear.
WHO, EMA, German national medical authorities etc. all say there's no evidence of a link with the vaccine.
Millions of people have had it. Most have been old or had underlying health problems. That's why they've been vaccinated. It would be extraordinary if none had died, vaccine or no vaccine.
There have been scares over the BioNTech/Pfizer vaccine in Norway & the USA. 41 dead in care homes! 270 dead after vaccinations! In both cases, no more than one would expect in those groups if they had not been vaccinated. Indeed, in the USA the death rate in the first few weeks after vaccination was significantly lower than in their unvaccinated contemporaries. Didn't stop screams of "Vaccine deaths!".
Oxford/AstraZeneca - same same.
Remember, everyone dies after having a vaccination. The only thing in doubt is when.
P.S. Mrs B & I both had what felt like mild flu for a couple of days after ours - both BioNTech/Pfizer.
