According to a report published in the Journal of the American Medical Association (JAMA), people who have received the modern vaccine are more likely to have side effects than those who receive the other vaccines, including the Pfizer vaccine, injection site pain, joint pain, and severe chills. Have experienced.
In the study, reports collected by the program of one of the Centers for Disease Control and Prevention called “v-safe” Was analyzed. The center’s program is based on text messages and tracks the side effects of vaccine recipients. For this purpose, after each dose of the vaccine, people who wish to participate in the program are asked to take part in a daily survey and report any symptoms such as fatigue or muscle aches.
More than 3.6 million people who received their first dose of Covid-19 vaccine before March 23, 2010 took part in the survey. About 70% of these people claim to have experienced a reaction such as pain or swelling at the injection site, and the rest of the vaccine recipients have reported more widespread reactions such as fatigue or chills.
Statistical studies show that most people who experience one of these side effects after vaccination have received the modern vaccine.
Of the 1.4 million people who received the second dose of the vaccine, approximately 82% of those who received the second dose of the modern vaccine felt pain at the injection site compared to others. Overall, 74% of recipients of the modern vaccine reported experiencing some side effects after receiving the vaccine. The most reported case is chills, which more than 40% of these people have reported. In contrast, only 22 percent of people who were vaccinated with Pfizer reported chills.
The report also noted that people over the age of 65 had fewer side effects than other people, regardless of the vaccine they received.
This study did not mention the severity of side effects, so it is not clear how severe the side effects of the modern vaccine are compared to other vaccines. In general, the reported side effects are similar to those previously reported in clinical trials.
