How do we know if the covid-19 vaccine being produced will be safe without long term side-effects?
Each vaccine trial has a required Data Safety Monitoring Board (DSMB) composed of a group of experts who act independently of the sponsoring company.
Regulatory bodies involved include the FDA in the U.S., the European Medicines Agency and Health Canada.
The Oxford vaccine was temporarily halted because of a neurologic complication, transverse myelitis, and after careful review received authorization to proceed in the U.K.
In the U.S., the trial restarted after a further one-month delay by the FDA, indicating how carefully they take safety and their independence from the political pressure applied.
Drug company CEOs have vowed to not rush development for profit over safety. Even if you don’t trust them, the lessons from huge multibillion-dollar class action settlements that were due to inappropriate shortcuts are an excellent deterrent.
With this all being said, knowing the true long term side effects of the vaccine will only be known with time.
