Nearly two years later, American scientists have developed an effective vaccine against all variants of the SARS-CoV-2 virus.
According to a report in Defense One magazine, US military scientists have developed a vaccine called Spike Ferritin Nanoparticle (SpFN) that can block all variants of the SARS-Cov-2 virus that caused the pandemic. . Coronavirus disease. -19, including variants that have already appeared and may appear in the future.
WRAIR Director of Infectious Diseases Kayvon Modjarrad said that early animal experiments earlier this year showed positive results. At the same time, the first phase of human trials testing Omicron strains and other strains ended this month with positive results.
SpFN is prepared based on the “self-assembled protein nanoparticles” technology. Unlike existing vaccines that use mRNA to trigger the immune system, SpFN works through a spherical 24-sided molecule similar to a football.
Each type carries a part of the mutant protein of the virus, which can trigger the body’s immune response. The shape of the nanoparticles allows scientists to connect the spikes of the coronavirus strain to different sides, thereby protecting the body from multiple mutations at the same time.
With the release of information about this new super vaccine called SpFN, the Omicron variant may trigger the next wave of infections. On December 1, the United States recorded the first case of Omicron infection in California. But so far, Omicron has become the main variant in the United States, accounting for 73% of all new Covid-19 infections in the country and up to 90% in New York and New Jersey.
