It may usually take ten to fifteen years to develop a new vaccine but the Covid-19 vaccines have been rushed to market in a matter of months.
Clinical trials normally last a minimum of 2 years. This is the usual protocol because this is the minimum length of time that is considered necessary to evaluate vaccine effects. What does this mean? Simply that the experimental safety trials for the COVID vaccines are not over. They started in 2020, so will not end before 2022. Since the vaccines are still experimental, anybody receiving them before the end of the trial period can rightly be considered a ‘Guinea pig’.
This alone is a sobering thought.
The Phase 3 clinical trial of BNT162b2 [Pfizer] began on July 27 and has enrolled 43,661 participants to date, 41,135 of whom have received a second dose of the vaccine candidate as of November 13, 2020. […] The trial will continue to collect efficacy and safety data in participants for an additional two years.

Who can tell what the long-term adverse effects may be, when we have not allowed enough time to observe them?
The mRNA COVID vaccines remain officially unapproved in the USA. In other words, they come with no guarantee.
The UK only gave a temporary emergency authorisation for the Pfizer, AstraZeneca and Moderna vaccines.
Interestingly, the AstraZeneca vaccine has been rejected in Switzerland, France, Germany and Sweden due to lack of clinical studies.
