According to the data released by the Food and Drug Administration, the most common side effects of the Moderna coronavirus vaccine include fatigue, headache, muscle pain as well as uncommon side effects that entail facial swelling, nausea, and vomiting.
The tolerance level of people over 64 was shown to be greater than younger people. As explained by doctors, the side effects are normal, because it is an indication that the shots have been effective because of the immune response. Physicians are also recommending people to take a few days off from work after getting their shot because the side effects are going to be more severe than a typical flu shot.
Moderna’s vaccine was authorized by the FDA recently and is reported to be more than 94% effective and also passed the standards of the agency for emergency usage. However, they also added that even though the side effects are not dangerous, they might cause discomfort.

Less than 6% of the recipients experienced symptoms for almost a week after receiving the dose. Eleven of the participants reported experiencing fever for more than a week, seven from the vaccine group, and four from the placebo.
