The following principles were ignored during the Covid crisis:

The licensing of novel Covid mRNA vaccines is based on emergency authorisations (in the EU, decree 507/2006, in the US Emergency Use Authorisation) due to the absence of completed Phase III studies at the time of the immunisation campaigns. The latter therefore have to be regarded as experimental. Nevertheless people were put under pressure to get vaccinated. In countries like Austria, Germany, France or Italy people were even forced by law to get vaccinated under threat of severe penalty or professional ban.
