The CDC reports that 8 out of 10 of the COVID deaths in the U.S. have been in adults 65 years old and older. Due to their evident vulnerability, older citizens featured prominently in the groups that the CDC prioritized to receive the vaccine. Group 1a was healthcare personnel and residents of long-term care facilities, while 1b included frontline essential workers and people aged 75 years and older who aren’t living in care facilities. Now, a new study from the CDC of COVID vaccines given between Dec. 14 and Jan. 13 showed that seniors are far less likely to experience side effects. According to the report, which was published in the Morbidity and Mortality Weekly Report on Feb. 26, less than 3.7 percent of people aged 65-74 years old experienced adverse side effects after receiving the vaccine. (The figures were broadly similar across both the Pfizer-BioNTech and Moderna vaccines.) The figure dropped even lower to 1.2 percent in the next age bracket up (75-84 year olds). By contrast, 64.9 percent of 18-49 year olds reported an “adverse event” after being vaccinated.

William Schaffner, MD, a professor of preventive medicine and infectious diseases at the Vanderbilt University School of Medicine in Nashville, added to the AARP that the adverse effects we feel post-vaccine tend to be milder in older people because “their immune systems are not responding as vigorously as a young person’s, but they still get 95 percent protection from the virus.” That’s great news for the many older people who have had to spend the last year shielding and being extra cautious because of the virus–when it comes to vaccination, you’re going to get all the benefits, and far fewer of the downsides.

Despite the study’s findings, the CDC reports on their website under the guidance “What Older Adults Need to Know About COVID-19 Vaccines” that there are five common side effects to look out for, even for those over 65. According to the agency, “pain where the shot is given, fever, chills, tiredness, or a headache for 1-2 days” are all frequent reactions to the vaccine.
