Response to Plan for Supplemental Vaccine Doses for Vaccinated Individuals 

“The Infectious Diseases Society of America (IDSA) appreciates that HHS is planning to provide vaccinated people with a supplemental dose of vaccines if the FDA and CDC recommend a supplemental dose following a thorough and transparent evaluation of the evidence. Planning is a critical public health activity and plans announced today will help minimize delays in action upon potential expert recommendations for supplemental COVID vaccine doses.

As the virus changes and more information becomes available, the public health response must keep pace. As with previous vaccine recommendations, independent review by the FDA and CDC, including by their respective independent advisors in the Vaccines and Related Biologic Products Advisory Committee (VRBPAC) and the Advisory Committee on Immunization Practices (ACIP), is a critical and necessary part of this process. 

Making supplemental doses available to individuals in the US must be done in concert with maximizing efforts to provide COVID-19 vaccination to low- and middle-income countries.  We cannot successfully end this pandemic without global vaccine equity.

The evidence is clear that vaccination remains the best way to protect against being hospitalized or dying from COVID-19. Infectious diseases experts urge everyone who is eligible to get vaccinated.” 

Barbara D. Alexander, MD, MHS, FIDSA – President Infectious Diseases Society of America
