The CDC updated this information September 12,2023. Based on a review of the history of the COVID-19 Vaccine--the most monitored Vaccine in history--the shot itself does not present such a risk. Anaphylaxis after COVID-19 vaccination is rare. It has occurred at a rate of approximately 5 cases per one million vaccine doses administered. Anaphylaxis, a severe type of allergic reaction, can occur after any kind of vaccination. If it happens, healthcare providers can effectively and immediately treat the reaction.
I found five research papers on this subject. The following lines are from these clinical investigations:
Synopsis: This study found that rates of death among people who received COVID-19 vaccines were lower than those of people who did not receive COVID-19 vaccines. In the largest study of its kind to date, the authors found no increased risk of death among people who received the vaccines.
Synopsis: Using data from the Vaccine Safety Datalink (VSD), this study found that rates of death among people who received COVID-19 vaccines were lower than those of people who did not receive COVID-19 vaccines. The authors determined that there is no increased risk of death among COVID-19 vaccine recipients.
Synopsis: The authors of this study analyzed VAERS reports of death after COVID-19 vaccination and found that rates of death after vaccination were lower than background rates of death from any cause in the general population. The findings in this study do not suggest an association between COVID-19 vaccination and overall increased rates of death.
Synopsis: The authors of this study reviewed the initial six months of mRNA COVID-19 vaccine safety data from December 2020 through June 2021 in VAERS and v-safe and found that the most commonly reported side effects of mRNA vaccines were mild and short in duration.
