The most concerning narrative from this past week involves the discovery of rare blood clots that could be associated with the Johnson & Johnson vaccine. I’ve argued that the initial pause on this vaccine was the right decision, though I worry that the length of the pause is allowing anti-vaccine activists to spread disinformation about vaccine safety. Here’s how we need to reframe the pause. Federal health officials are being so cautious that they are willing to stop for a possible side effect that is literally so rare that it’s one in a million. That should make Americans feel more reassured about the Pfizer and Moderna vaccines, which have been given to more than 100 million people without a red-flag safety concern arising. If anything, there’s legitimate criticism about whether the pause will harm individuals who otherwise could have been vaccinated during this time — but no one should doubt that vaccine safety is the top priority.
