American and European researchers have found that the RNA vaccine against the coronavirus rarely causes serious side effects in children. The same can be said about injections against other diseases based on weakened viral particles. The results of the researchers’ observations were published in the journal JAMA Network Open.

Studies have shown that the frequency and nature of side effects after taking the Pfizer vaccine were generally comparable to how often and how severe such incidents occurred after taking other childhood vaccines that were not related to the coronavirus. These data will help comprehensively evaluate the safety of RNA vaccine for young children, the respective article stated, in part.

Last spring, Israeli researchers found that Pfizer and Moderna's RNA vaccines against the coronavirus extremely rarely caused myocarditis, an inflammatory disease of the heart muscle, the complications of which can lead to heart failure or sudden cardiac arrest. Later, researchers discovered that after vaccination, myocarditis occurred most often in children and adolescents.

These findings have led researchers to examine in detail all possible side effects associated with the injection of RNA vaccines.
