Quite possible, but nothing about enlarged heart.
People. Trolls are going to troll. Myocarditis is inflammation of the heart. Inflammation is one way a heart can be enlarged. It doesn’t take long. Even disruption of the functioning of a valve can enlarge the heart.
Have you ever heard of this number of enlarged hearts among the young following vaccination? Uhm. No. The trolls will dilute and distract -it’s our job as citizens and parents to push back on vaccine harm and people like Fauci, the CDC, and trolls.
