The summary is true: People who received the Moderna COVID-19 vaccine said they had more side effects than those receiving Pfizer / BioNTech images, according to new data published this week in. JAMA.
The study analyzed reports compiled through a Centers for Disease Control and Prevention project called v-safe, a text-based program designed to track side effects in vaccine recipients. In the first week after each vaccination, registered people will be asked to complete a daily survey about symptoms such as fatigue or arm pain.
More than 3,600,000 people who got their first COVID-19 vaccine before Feb. 21 registered for v-safe and underwent at least one test, about 70 percent of those people said they had a reaction in the area. Injecting drugs such as pain or swelling and half had a general reaction such as fatigue or chills. For both people, people who received the Moderna injection were more likely to have side effects – 73 percent had an injection site reaction, compared with 65 percent of those who received Pfizer / BioNTech.About 51 percent of Moderna recipients had symptoms. Whole body, compared with 48 percent of those who received Pfizer / BioNTech.
The gap widened after the second dose of approximately 1.4 million people completed those check-ins.Nearly 82 percent of those who received the second Moderna infusion had pain at the injection site compared to those who used Pfizer / BioNTech. Less than 69 percent overall, 74 percent of people said they had a typical reaction after they had a Moderna shot, compared with 64 percent of those who received Pfizer / BioNTech.The biggest difference was the chills, which were induced. Of the 40 percent of people who took the Moderna, and only 22 percent took the Pfizer / BioNTech photo.
People over 65 are less likely to have side effects than those under 65, regardless of the vaccine received.
V-safe did not ask people how severe their symptoms or reactions were, so it was unclear if one vaccine caused more disruptive effects than the other. Additionally, the person who used the v-safe might not be a representative example of the person who was shot. Only 10 percent of those who apply for the program after being vaccinated.
Overall, side effects and the frequency of side effects were similar to those seen in clinical trials testing these vaccines. Clinical trials have given researchers and doctors a better understanding of the types of side effects people can expect after receiving images.
Anyone who receives the COVID-19 vaccine can apply for a v-safe here.
