Misleading: Vaccine Heart Enlargement

The Israeli government recently announced that they are investigating reports of heart inflammation experienced by some recipients of the Pfizer vaccine. Usually, they occurred after the second dose. Some social media users posted about it on Twitter.

Having an enlarged heart – officially called cardiomegaly – can cause chest pains, shortness of breath, and other symptoms. Depending on the severity of the condition, it can result in blood clots and other serious health complications. 

These reports come not long after the AstraZeneca vaccine was found, on very rare occasions, to cause blood clots.
