New evidence confirms COVID-19 vaccines are overwhelmingly safe::More than 38 million COVID-19 vaccine doses have been administered in Ontario as of Oct. 8, with 23,002 reports of adverse reactions, an incidence of 0.06 per cent, Public Health Ontario says


Genuinely impressive how a vaccine made under the conditions and time constraints COVID faced is so effective.
That’s because most of the groundwork in developing mrna vaccines had already been done for years and years. This wasn’t “how do we invent a vaccine for covid?”, this was “how do we adapt this proven, well-understood vaccine tech so that it works for covid just like it does for the ebola virus that we originally developed it for?”
There was also a large amount of money thrown at developing the vaccine because of the virus’ significant economic impacts.
