NIH Candidate vaccine could provide enhanced breadth of protection against emerging SARS-CoV-2 variants.
A Phase 1 trial testing the safety of an experimental nasal vaccine that may provide enhanced breadth of protection against emerging variants of SARS-CoV-2, the virus that causes COVID-19, is now enrolling healthy adults at three sites in the United States. The National Institutes of Health (NIH) is sponsoring the first-in-human trial of the investigational vaccine, which was designed and tested in pre-clinical studies by scientists from NIH’s National Institute of Allergy and Infectious Diseases (NIAID) Laboratory of Infectious Diseases.
“The rapid development of safe and effective COVID-19 vaccines was a triumph of science, and their use greatly mitigated the toll of the pandemic,” said NIAID Director Jeanne M. Marrazzo, M.D., M.P.H. “While first-generation COVID-19 vaccines continue to be effective at preventing severe illness, hospitalizations, and death, they are less successful at preventing infection and milder forms of disease. With the continual emergence of new virus variants, there is a critical need to develop next-generation COVID-19 vaccines, including nasal vaccines, that could reduce SARS-CoV-2 infections and transmission.”
