There was no data at all that showed that the vaccine stopped infection or stopped transmission.

Previously: There was no data at all that showed that the vaccine stopped infection or stopped transmission. [Distorted]: When the vaccines were authorized, there was indeed no evidence they prevented transmission, and some officials later overstated the protection. But 'no data at all' goes too far. The original trials showed about 95% fewer symptomatic infections, and studies from Israel, the UK and the CDC in 2021 and 2022 found vaccinated people were less likely to catch and spread the virus, though that protection faded, especially with Omicron. We rate this distorted rather than false, as an earlier page did, because the point about authorization-era data is accurate. This would be wrong if those household and cohort studies were shown to find no reduction in infection or transmission.

Now: There was no data at all that showed that the vaccine stopped infection or stopped transmission. [Distorted]: Rogan says there were no data at all. The original Pfizer efficacy analysis did show fewer symptomatic COVID cases. That endpoint differs from preventing every infection or proving interruption of transmission, neither of which the original trial established. Officials' categorical claims of complete protection should not be defended by overstating what was tested.

Replace a secondary fact check with the original regulatory evidence and narrow the correction to the measured endpoint.
