On Wednesday, a safety group associated with the Centers for Disease Control and Prevention announced a possible link between heart inflammation and young people who have received the COVID-19 vaccine. The finding raises alarm bells at a time when the U.S. vaccination rate has sharply declined to approximately 820,000 per day.

The White House has acknowledged it won’t meet a July 4 goal of getting 70% of U.S. residents vaccinated with at least one dose. This latest news is sure to give some even more pause. COVID-19 vaccines have been heavily scrutinized from the start. The research, testing, trials, mass production, distribution, emergency approval from the Food and Drug Administration, and administration all occurred in a remarkably short time frame. That alone has made some people extremely reluctant. Worst of all, the vaccines have become another partisan talking point.
