Something like 45000 people tested the Oxford vaccine before it was
approved for general use.  No adverse effects were noted.  A few days
after the Pfizer vaccinations started, two people had temporary adverse
effects - these were people who had a history of severe allergic
reactions, so now the advice is not to vaccinate people with such
histories.

So far we've had about 1.5 million people vaccinated, and that's all
the problems.  Now do your arithmetic, and you'll see the risk of the
vaccine is much less that 0.01%.

You've just stated something that is not true.  The vaccines (not a
treatment, incidentally) have been tested just as well and as
thoroughly as all previous vaccines.  Don't let the short timescale
fool you.

Nearly 30 years ago, I joined an engineering project right at its
start.  This was the first project in the company to use "concurrent
engineering" practices.  Everything was planned to happen in parallel
as far as possible, and without delay between stages when serial flow
was inevitable.  That's what has been done in the case of these vaccines
- plus a great deal of pressure, in view of the 7-figure mortality.
