US Clinical Trial Showed Novavax Vaccination is Safe

The investigational Vaccination known as NVX-CoV2373 achieved 90.4 percent efficacy in preventing symptomatic COVID-19 disease in Phase 3 clinical trial, including 29,960 adult volunteers in the United States and Mexico. The individual was completely immune to both moderate and severe illness. The vaccination was 91.0 percent effective in preventing symptomatic COVID-19 disease in persons at high risk of acquiring COVID-19 complications.

The investigational Vaccination was generally well-tolerated, according to safety statistics. The most prevalent local symptoms among participants were mild-to-moderate injection site discomfort and soreness. At the same time, the most common systemic effects were fatigue, headache, and muscle soreness lasting less than two days.

The investigational vaccine was created by Novavax, Inc. of Gaithersburg, Maryland, which also conducted the PREVENT-19 clinical trial. Adult volunteers were enrolled in the PREVENT-19 trial beginning in late December 2020 at 119 study locations, including those in the NIAID-supported COVID-19 Prevention Network (CoVPN). Participants were given two shots, one of the investigational vaccination and saline placebo, 21 days apart.

NVX-CoV2373 was given to two volunteers in a 2:1 ratio, with one participant receiving a placebo and the other receiving NVX-CoV2373. The investigators and participants didn’t know who got the proposed Vaccination because the trial was blinded.PREVENT-19 was meant to see if NVX-CoV2373, compared to placebo, can prevent symptomatic COVID-19 disease seven days or more after the second injection. According to the researchers, the findings are based on 77 incidences of symptomatic COVID-19 detected among study participants from January 25 to April 30, 2021.

According to the researchers, there were 63 cases among the approximately 10,000 placebo participants and 14 cases among the about 20,000 people who received the experimental vaccination. The investigators rated 10 of the 63 COVID-19 instances in the placebo group as moderate and four as severe. In the investigational vaccine group, there were no incidences of moderate or severe illness.
