Pfizer (finally) releases the list of side effects of its vaccines.

The Reality Behind the Claim

First, it’s important to clarify: Pfizer did not suddenly release a new or secret list of side effects in 2026. Information about vaccine side effects has been publicly available for years through regulatory agencies, clinical trial data, and official product documentation.

Health authorities and Pfizer itself have consistently published safety data as part of ongoing monitoring systems used worldwide.

In fact, fact-checking organizations have previously flagged similar viral posts as misleading, noting that lists shared online often include unverified or misinterpreted reports rather than confirmed side effects.
