What if he had ended this tweet with "But: I will take any FDA approved vaccine." ?
Except - he was at exactly 280 characters, so he couldn't have added this without removing other text, or doing a multi-tweet message.

Maybe the character limits inherent in platforms like twitter cause many of the problems we're seeing right now, because people literally don't have the words to explain themselves.
It would be problematic for a medical doctor to disseminate medically incorrect information to the public and not correct or clarify it. Similarly, it is problematic for a scientist to disseminate scientifically incorrect information and not correct or clarify it. It would be a simple thing for him to simply tweet, "On x date I tweeted y. The evidence now suggests that this statement was incorrect." The science on this continues to evolve, acknowledging that sometimes we are wrong is not a stain on one's reputation. It is the mark of a scientist who is pursuing evidence rather than a narrative. Dr. Levitt is pursuing narrative over evidence, and his actions have consequences.
