Is the coronavirus vaccine safe?
In clinical trials for vaccines produced by pharmaceutical companies Pfizer and Moderna, participants did not experience any life-threatening events that were attributed to the vaccine. A risk of a rare condition called thrombosis with thrombocytopenia syndrome (TTS) has been reported following vaccination with the Johnson & Johnson/Janssen COVID-19 Vaccine. TTS is a serious condition that involves blood clots with low platelet counts. This problem is rare, and most reports were in women between 18 and 49 years old. For women 50 years and older and men of any age, this problem is even more rare.[/fusion_toggle]
No. COVID-19 vaccines are part of the most intensive vaccine safety monitoring effort in U.S. history, according to the
Centers for Disease Control and Prevention (CDC). COVID-19 vaccines were evaluated in tens of thousands of clinical trial participants in order to meet the Food and Drug Administration’s (FDA) rigorous scientific standards for safety, effectiveness and manufacturing quality needed to support
emergency use authorization (EUA).
On Aug. 23, 2021, the FDA officially approved the Pfizer-BioNTech vaccine in individuals age 16 and older. The vaccine now will be marketed as Comirnaty.
Over 346 million doses of COVID-19 vaccine have been given in the U.S. as of Aug. 2, 2021, since they were authorized for emergency use by FDA. The vaccines will continue to undergo safety monitoring that includes using both established and new safety monitoring systems to make sure that COVID-19 vaccines are safe.
