Moderna COVID Vaccine side effects by duration, gender, age and dose - a phase IV clinical study of CDC and FDA data
Summary:
Side effects are reported by people who have Moderna COVID Vaccine. Common side effects include headache among females and pyrexia among males.
The phase IV clinical study is created by eHealthMe based on 392,578 reports from the CDC and the FDA, and is updated regularly. You can use the study as a second opinion to make health care decisions.
Phase IV trials are used to detect adverse drug outcomes and monitor drug effectiveness in the real world. With medical big data and AI algorithms, eHealthMe is running millions of phase IV trials and makes the results available to the public. Our original studies have been referenced on 600+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.
