The Centers for Disease Control & Prevention said Friday that the two Covid-19 vaccines approved in the United States for use in the United States are reassuring safety profiles.
Following administration of 13.8 million doses of the Pfizer-BioNTech and Modern vaccines to the U.S. population, most reports indicated that non-serious side effects of this type were expected, such as headaches and fatigue. No deaths were attributed to the vaccines, the data showed.
The CDC collected data between 14 December 2020 and 13 January 2021 of both an existing national adverse incident monitoring system and its own safety monitoring system set up for Covid-19 vaccines.

During that time, 6,994 reports of adverse events after vaccination were recorded in the national surveillance system, with 90.8 percent of them as non-serious and 9.2 percent as serious.
Rare cases of anaphylaxis, a severe allergic reaction requiring medical attention, have been reported with both vaccines at a rate of 4.5 cases per million doses administered, down from the agency’s previously reported dose of 5 per million doses. The rate of anaphylaxis linked to Covid shots is similar to other vaccines, the director of the CDC, dr. Rochelle Walensky, said Friday during the Covid-19 response team in the White House.
“Healthcare and vaccine providers can rest assured about the safety of Pfizer and Moderna Covid-19 vaccines,” the CDC said in its weekly report on morbidity and mortality.
A total of 113 deaths were reported, including death certificates and autopsy reports. According to the CDC report, no causal link was found between Covid-19 vaccination and deaths.
