Washington: A new study has revealed that those taking the Moderna vaccine have reported more side effects than people who get the Pfizer/BioNTech vaccinations.
The study analyzed reports collected through a Centers for Disease Control and Prevention program called v-safe. It’s a text message-based program designed to track side effects in vaccine recipients. For the first week after each vaccine dose, people who enroll are prompted to fill out a daily survey about any symptoms, like fatigue or arm pain.
The study, published in the Journal of the American Medical Association, analyzed reports collected via a Centers for Disease Control and Prevention (CDC) program called v-safe that tracks side effects in vaccine recipients.
A total of 3,643,918 people were enrolled in v-safe and completed at least one health survey within seven days following their first vaccine dose before February 21, and 1,920,872 v-safe participants reported receiving a second vaccine dose and completed at least one daily health survey within seven days following the second dose.
Nearly 70 percent of those said they had some kind of injection site reaction, like pain or swelling, and half had generalized reactions like fatigue or chills.
"A greater percentage of participants who received the Moderna vaccine, compared with the Pfizer-BioNTech vaccine, reported reactogenicity; this pattern was more pronounced after the second dose," the researchers noted.
People who got a Moderna shot were more likely to have a side effect. 73 percent had an injection site reaction, compared with 65 percent of people who had a Pfizer/BioNTech dose.
Nearly 51 percent of Moderna recipients had full-body symptoms, compared with 48 percent of people who got the Pfizer/BioNTech shot.
