Just googled the risks from Pfizer and they seem not that different
chest pain or pressure,
pain spreading to your jaw or shoulder,
nausea,
sweating,
vision changes,
sudden vision loss,
severe shortness of breath,
cough with foamy mucus,
ringing in your ears,
sudden hearing loss,
irregular heartbeat,
swelling in your hands, ankles or feet,
seizure (convulsions), and
lightheadedness
Then I realised that this was for Pfizer Viagra.
Oh well, I guess most 50 plus year old blokes would be happy to take the risk if they could get their hands on Pfizer Viagra.
Not sure why a COVID vaccine is a problem with similar risks
