Pfizer BioNTech Covid Vaccine and Atrioventricular block complete - a phase IV clinical study of CDC and FDA data


Atrioventricular block complete is found among people who get Pfizer BioNTech Covid Vaccine, especially for people who are male, 60+ old, and in the first week of getting the vaccine.

The phase IV clinical study analyzes which people get Pfizer BioNTech Covid Vaccine and have Atrioventricular block complete. It is created by eHealthMe based on reports of 286,220 people who have side effects when getting Pfizer BioNTech 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.

With medical big data and AI algorithms, eHealthMe enables everyone to run phase IV clinical trial to detect adverse drug outcomes and monitor effectiveness. Our original studies have been referenced on 600+ peer-reviewed medical publications including The Lancet, Mayo Clinic Proceedings, and Nature. Most recently, phase IV clinial trails for COVID 19 vaccines have been added, check here.
