US Army Creates Single Vaccine Against All COVID, SARS Variants


Reposted on slashdot:

Within weeks, scientists at the Walter Reed Army Institute of Research expect to announce that they have developed a vaccine that is effective against COVID-19 and all its variants, even Omicron, as well as previous SARS-origin viruses that have killed millions of people worldwide. Walter Reed's Spike Ferritin Nanoparticle COVID-19 vaccine, or SpFN, completed animal trials earlier this year with positive results. Phase 1 of human trials, which tested the vaccine against Omicron and the other variants, wrapped up this month, again with positive results that are undergoing final review, Dr. Kayvon Modjarrad, director of Walter Reed's infectious diseases branch, said in an exclusive interview with Defense One. The new vaccine will still need to undergo phase 2 and phase 3 trials.


Unlike existing vaccines, Walter Reed's SpFN uses a soccer ball-shaped protein with 24 faces for its vaccine, which allows scientists to attach the spikes of multiple coronavirus strains on different faces of the protein. The vaccine's human trials took longer than expected, he said, because the lab needed to test the vaccine on subjects who had neither been vaccinated nor previously infected with COVID. The next step is seeing how the new pan-coronavirus vaccine interacts with people who were previously vaccinated or previously sick.

Walter Reed is working with a yet-to-be-named industry partner for that wider rollout.
