The Centers for Disease Control and Prevention (CDC) says that a preliminary COVID-19 vaccine "safety signal" has been identified and is investigating whether the Bivalent Pfizer-BioNTech vaccine creates an increased risk of ischemic stroke in people 65 and older.

In the Friday statement, the CDC said that the preliminary signal hasn't been identified with the Bivalent Moderna COVID-19 vaccine.
