According to a recent study, more people taking Moderna’s coronavirus vaccine reported side effects than those who received the Pfizer shot.
Researchers have analyzed reports from more than 3 million wax recipients collected via v-safe, a center for disease control and prevention program that monitors responses to vaccinations.
Nearly 70 percent said they had some reaction at the injection site, such as pain or swelling, and half reported common side effects, such as fatigue or chills.
‘A greater percentage of participants who received the Moderna vaccine, compared to the Pfizer-BioNTech vaccine, reported reactogenicity; this pattern was more pronounced after the second dose, ”the researchers said.
Of those who received the Moderna shot, 73 percent said they had a reaction at the injection site, compared with 65 percent of those who received Pfizer’s vaccine, the study found.
Nearly 51 percent of Moderna recipients reported experiencing body symptoms, compared with 48 percent of those who received the Pfizer shot.
The reports come from more than 3.6 million people who received their first dose of COVID-19 vaccine before February 21 and completed at least one v-safe health survey within seven days of being pinned.
The gap widened after the second dose, according to reports from about 1.9 million people who completed the investigations after receiving the number 2, the study reads.
Nearly 82 percent of people who received their second Moderna vaccine have injection site pain, compared with less than 69 percent of those with Pfizer.
Overall, 74 percent of Moderna recipients said they experienced body symptoms, compared to 64 percent of people who received the Pfizer wax.
Specifically, about 40 percent of people with Moderna reported that they get colds, compared to just 22 percent of Pfizer recipients.
“Data from millions of v-safe participants indicate that injection site pain is common after both the first and second doses of either mRNA-based vaccine,” the researchers noted.
The study was published Monday in peer-reviewed medical journal JAMA.
