Over the summer of 2021, concern grew that the vaccines were not providing the near-perfect protection against symptomatic disease and transmission that had first emboldened the administration to jettison other public health measures.
It was initially unclear whether the issue was Delta’s higher transmissibility or waning immunity from vaccines, as the first groups had been vaccinated nearly a year prior. There was noticeable concern from CDC, which acknowledged the “war has changed” in a set of leaked slides from July 29, 2021. Of particular concern were case reports from Massachusetts and internationally of high viral loads observed among those who were vaccinated and infected. In late July, CDC reversed course on its mask guidance and recommended indoor masking for all, including the fully vaccinated, in counties with high transmission. In late September 2021, CDC reversed course on its quarantine guidance, which had previously stated that fully vaccinated people should not quarantine after a known SARS-CoV-2 exposure.
These changing epidemiologic realities could have brought about a course correction and a push for other public health policies to complement vaccination. Instead, the administration mostly adapted by shifting its messaging.
