COVID-19 vaccine candidates are rigorously tested for safety during clinical trials, unlike thalidomide; misleading to equate the two
In spite of the expedited development timeline, COVID-19 vaccine candidates remain subjected to the same level of safety standards as any other vaccine, and must demonstrate clinical efficacy and safety before being approved for use. Thus far, COVID-19 vaccine frontrunners, such as those by Pfizer, Moderna, and AstraZeneca/Oxford, have demonstrated a high level of safety during clinical trials.
