Dr. Anthony Fauci, the former Director of the former National Institute of Allergy and Infectious Diseases (NIAID), claimed the effectiveness of coronavirus vaccines is a “complicated issue” when he testified before lawmakers on Capitol Hill on Monday. This was the first time Fauci has testified publicly since retiring at the end of 2022. The former Chief Medical Adviser to Joe Biden was grilled by members of the House Oversight Select Subcommittee on the Coronavirus Pandemic regarding a range of subjects relating to the origins of COVID-19 and the government response.
Leading off the congressional hearing, Select Committee Chairman Brad Wenstrup (R-OH) pressed Fauci on the vaccines’ effectiveness, highlighting that they did not entirely prevent virus transmission as initially anticipated.
“Did the COVID vaccine stop transmission of the virus?” Wenstrup inquired.
“That is a complicated issue,” Fauci began, acknowledging that the initial formulation of the vaccines had some impact. “Not 100 percent, not a high effect,” he admitted, elaborating that the vaccines “did prevent infection and subsequently, obviously transmission” to a certain extent.
Fauci further clarified that early assumptions about the vaccines‘ ability to prevent infection and transmission proved inaccurate over time. “It’s important to point out that something we did not know early on, which became evident as the months went by, is that the durability of protection against infection, and hence transmission, was relatively limited,” Fauci noted. He continued: “In the beginning, it was felt that it did prevent infection and thus transmission, but that was proven as time went by not to be a durable effect.”
When questioned about the overall efficacy of the coronavirus vaccine, Fauci responded, “I don’t believe any vaccine is 100 percent effective.”
