'13 billion Covid vaccines have been given.

Yes 13 BILLION. Not a typo.

13,000,000,000

It's extremely safe.

Yet anti vaxxers still call it "experimental"

I'm guessing they also think electricity, and the wheel as a means of transport, are also experimental.' Dr Neil Stone, Twitter

The morbidity and mortality of the vaccines are tiny compared to those of Covid. And yet people still worry about vaccine-induced myocarditis, for example.

Part of the problem is simple innumeracy.
