Here’s the CDC’s database for adverse reactions to vaccines, including the COVID-19 vaccines. The data is submitted voluntarily. Anyone – healthcare providers, the public – can submit a report.

Vaccine Adverse Event Reporting System (VAERS)

The Vaccine Adverse Event Reporting System (VAERS) database contains information on unverified reports of adverse events (illnesses, health problems and/or symptoms) following immunization with US-licensed vaccines. Reports are accepted from anyone and can be submitted electronically at www.vaers.hhs.gov.

Results are updated on Fridays, so this data is several days old. It’s not a complete list by any means and it may not be very accurate but it does provide some data. I don’t know how many people were vaccinated then but this shows 353 total adverse events. VAERS is known to underreport.

These are the top adverse reactions (to all manufacturers’ vaccines combined: Pfizer, Moderna, etc.), in alphabetical order. (Top reaction is headache.):
