COVID-19 Vaccine Opponents Misrepresent CDC Webcast on Causes of Blood Clots

The Centers for Disease Control and Prevention hosted an online seminar about the treatment of blood clots, which is expected to grow as the U.S. population ages and the obesity rate increases.

COVID-19 vaccines have been found to be safe and effective in trials and real-world conditions.

Misrepresentation of Germany’s Data on Unverified COVID-19 Vaccine Side Effects

Misrepresentation of Germany’s Data on Unverified COVID-19 Vaccine Side Effects

Viral claims have repeatedly misrepresented unverified data from a U.S. vaccine safety system that encourages reports of any potential side effects — whether they’re likely to be caused by the vaccine or not. Now we’re seeing the same phenomenon with a similar system in Germany. Some have wrongly claimed Germany found the COVID-19 vaccine caused “serious side effects” in a large number of people.
