The Centers for Disease Control and Prevention (CDC) has advisable that Novavax’s COVID-19 vaccine be used as one other main collection choice for adults within the United States ages 18 years and older. The Food and Drug Administration (FDA) beforehand approved for emergency use the protein-based vaccine, referred to as NVX-CoV2373.

The National Institute of Allergy and Infectious Diseases (NIAID), a part of the National Institutes of Health; the Biomedical Advanced Research and Development Authority (BARDA), a part of the U.S. Department of Health and Human Services’ Office of the Assistant Secretary for Preparedness and Response; the Department of Defense (DoD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND); and the Defense Health Agency supported the event of NVX-CoV2373 as a part of the U.S. authorities’s fast response to develop protected and efficient COVID-19 vaccines.

DoD funded the early growth of expertise used within the NVX-CoV2373 vaccine, and NIAID, BARDA, JPEO-CBRND and DoD supplied help for scientific trials evaluating its security and efficacy. BARDA additionally supplied funding and experience to help manufacturing and procurement of the vaccine.

NVX-CoV2373 comprises a stabilized type of the SARS-CoV-2 spike protein—a floor protein that facilitates entry to human cells. The strategy for stabilizing the spike protein was invented by NIAID scientists and their collaborators. The spike proteins are organized in tiny protein particles known as nanoparticles. The vaccine is formulated with a saponin‐based mostly adjuvant. Saponins are naturally occurring compounds from soapbark timber. Adjuvants are generally added to vaccines to boost immune responses.

The U.S. authorities supported the Phase 3 scientific trial referred to as PREVENT-19 that enrolled 29,960 grownup individuals within the United States and Mexico between Dec. 27, 2020, and Feb. 18, 2021. Participants have been randomly assigned to obtain two doses of the candidate vaccine 21 days aside or two injections of a saline placebo. Randomization occurred in a 2:1 ratio, with two volunteers receiving NVX-CoV2373 for each who acquired placebo. Results revealed within the New England Journal of Medicine confirmed the candidate vaccine was 90.4% efficient in stopping symptomatic COVID-19 amongst trial individuals and 100% efficient in stopping moderate-to-severe COVID-19. The trial was performed earlier than the Omicron variant of SARS-CoV-2 turned dominant.

The PREVENT-19 trial expanded in May 2021 to enroll adolescents ages 12 to 17 years. Novavax has famous that the trial ends in adolescents demonstrated comparability to these noticed within the grownup inhabitants. PREVENT-19 is also evaluating a 3rd shot or booster dose in each grownup and adolescent individuals. In addition, NIAID is learning NVX-CoV2373 within the Phase 1/2 “mix & match” trial, through which grownup volunteers who’ve been totally vaccinated towards COVID-19 obtain booster doses of various COVID-19 vaccines to find out the security and immunogenicity of blended boosted regimens.

Lawrence A. Tabak, D.D.S., Ph.D., Senior Official Performing the Duties of the NIH Director; Anthony S. Fauci, M.D., NIAID Director; and Gary Disbrow, Ph.D., BARDA Director, launched the next statements:

“This is the third COVID-19 vaccine available in the U.S. as a result of the unprecedented government research response to develop safe and effective COVID-19 vaccines, for which NIH spearheaded the clinical testing. This collaborative approach involving many public-private partners provides an important blueprint for pandemic preparedness now and into the future.” – Dr. Tabak

“People in the United States now have an additional COVID-19 vaccine available to them that offers protection against severe disease. The Novavax COVID-19 vaccine contains a SARS-CoV-2 protein and an adjuvant to boost the immune response. Other vaccines in routine use in the United States, including the hepatitis B vaccine, use this traditional protein-based platform. I continue to encourage all eligible adults and children to get vaccinated against COVID-19 and to stay up-to-date on boosters.” – Dr. Fauci

“We are pleased to see this vaccine achieve FDA authorization, giving Americans another option for a vaccine to protect against COVID, particularly with cases on the rise again. Even with other FDA-approved vaccines available, we continue to support development of flexible vaccine technologies like this one so that we can respond more rapidly to future public health emergencies as well as the current health crisis.” – Dr. Disbrow
