These Are the Side Effects of the New Johnson & Johnson Vaccine – Best Life

8 min read


Right now, Pfizer and Moderna are the only two coronavirus vaccines that have been authorized by the U.S. Food and Drug Administration (FDA). However, another COVID vaccine is expected to reach the authorization stage soon from Johnson & Johnson. Unlike the others, this vaccine is only one dose—but according to new research, it may work just as well as the others. New trial data published on Jan. 13 in the New England Journal of Medicine released information on the safety, efficacy, and possible side effects of Johnson & Johnson’s new vaccine.

During the trial, researchers with Johnson & Johnson randomly assigned 805 participants to receive a high or low dose of the vaccine—which is called Ad26.COV2.S—or a placebo. The researchers studied two age groups during this trial: healthy adults between the ages of 18 and 55 and those 65 and older. According to the study, 90 percent or more of all participants had neutralizing antibodies 29 days after getting vaccinated, and 100 percent had antibodies 57 days after getting their vaccine.

And while the excitement over the potential of getting your COVID vaccination done in just one shot is warranted, just like any other vaccination, you should expect some potential side effects. According to the study, there are five common side effects that may come from the new Johnson & Johnson COVID vaccine—which interestingly enough, were more largely common among those 18 to 55 than those 65 and older. Keep reading to find out what they are, and for more on vaccines, know that If You Take These OTC Meds, You Have to Stop Before Getting the Vaccine.
