Any coronavirus vaccine can cause unpleasant, but temporary, side effects that do not pose a threat to health and life, reports Newsweek, citing data from the American Medical Association.
Experts warn that the consequences of vaccination can be unpleasant, however, several injections must be made in order to form full-fledged immunity. Vaccines from Moderna and Pfizer, given in two doses approximately one month apart, are estimated to be up to 95 percent effective in providing immunity against SARS-CoV-2.
In trials of the Moderna vaccine, the only common “severe” side effect observed after the first dose was pain at the injection site, which occurs in 2.7 percent of patients. After the second dose, the most common serious side effect was fatigue, which was observed in 9.7 percent of participants. Muscle pain was experienced by 8.9 percent and joint pain by 5.2 percent. Another 4.5 percent reported headaches.
Details of the safety of the Pfizer vaccine have yet to be released, but BioNTech disclosed that the vaccine does not pose a serious health hazard. Previously, the most common side effects were fatigue and headaches, which occurred in less than 4 percent of the trial participants after the second dose.
Some experts have called on doctors and health officials to inform the public about possible consequences such as a strong rise in temperature. This will counter those who will use information about side effects to promote conspiracy theories against vaccination.
