Most Side Effects Of Pfizer Moderna Vaccines are Mild

Most Side Effects Of Pfizer Moderna Vaccines ae Mild  some side effects of mRNA vaccines from Pfizer and Moderna were low, according to researchers, and began to fade barely a day after they were given.






The Research

In a study published in The Lancet Infectious Diseases on Monday, a group of experts looked into the two mRNA-based COVID-19 vaccines used in the United States and presented their findings. The researchers analyzed data from two types of surveillance systems: a passive system called the Vaccine Adverse Event Reporting One (VAERS) and an active system called v-safe. Only individuals who were hired during the first six months of the vaccination program in the country were included in the study.










The researchers classified the reports obtained by VAERS as non-serious, serious, or deceased. On the other hand, throughout the full week following vaccination, v-safe survey reports were analyzed for reactogenicity, severity, and health implications of the vaccine dosage. Only data from the two systems was used in the observational study, which took place from December 14, 2020, to June 14, 2021.

Over 298 million doses of mRNA vaccines were delivered in the country during the study period. Pfizer vaccine doses accounted for about 167 million, whereas Moderna vaccine doses accounted for 132 million. After their initial dose, more than 4 million of the nearly 7 million individuals who reported unpleasant side effects complained of injection site pain, according to the researchers. After the second dose, the number increased to 5.6 million.




Following the first dose, 33.9 percent of participants (2.3 million) reported fatigue, while 55.7 percent (3.1 million) reported exhaustion after the second dose. After the initial dose, more than 1.8 million individuals reported headaches, with the number rising to 2.6 million after the follow-up dose. Overall, the reactions to the immunizations were minor, according to the study, and began to fade after 24 hours.

The Study’s Implications

The findings of a study supported by the Centers for Disease Control and Prevention (CDC) in the United States serve to establish the safety of mRNA vaccinations for those who are still afraid to get vaccinated in the midst of the ongoing epidemic. According to the researchers, the majority of the reported side effects of the Pfizer and Moderna vaccinations were modest and only lasted a short time.

“These statistics reassuringly show that reactions to both mRNA vaccines are often minor and decrease within one or two days – confirming observations from clinical trials and post-authorization surveillance,” one of the study’s authors, Tom Shimabukuro, told USA Today.

As the medical community continues to monitor the vaccines’ safety when the world entered the second year of the pandemic, CDC’s Hannah Rosenblum, who also helped author the large-scale study, stated that their findings should “bolster confidence that the mRNA COVID-19 vaccinations are safe.”
