Moderna COVID Vaccine and Cardiac flutter - a phase IV clinical study of CDC and FDA data

Summary:

Cardiac flutter is found among people who get Moderna COVID Vaccine, especially for people who are female, 60+ old, and in the first week of getting the vaccine.

The phase IV clinical study analyzes which people get Moderna COVID Vaccine and have Cardiac flutter. It is created by eHealthMe based on reports of 392,577 people who have side effects when getting Moderna COVID Vaccine 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.

On Nov, 08, 2022

392,577 people reported to have side effects after getting Moderna COVID Vaccine.

What is Cardiac flutter?

Cardiac flutter (abnormal heart rhythm) is found to be associated with 1,190 drugs and 645 conditions by eHealthMe.
