Pfizer BioNTech Covid Vaccine and Primary myelofibrosis - a phase IV clinical study of CDC and FDA data

Summary:

Primary myelofibrosis is reported only by a few people who get Pfizer BioNTech Covid Vaccine.

The phase IV clinical study analyzes which people get Pfizer BioNTech Covid Vaccine and have Primary myelofibrosis. It is created by eHealthMe based on reports of 401,887 people who have side effects while getting Pfizer BioNTech Covid Vaccine from the CDC and the FDA, and is updated regularly.

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 Jul, 27, 2023
