Army vaccine could protect against COVID and all future coronaviruses

White House chief medical adviser Dr. Anthony Fauci recently highlighted the government’s investment in a universal system Covid-19 vaccine which could successfully combat all variants. In one interview with NBC Thursday, Fauci said there was a concerted effort to develop a universal COVID vaccine that “would mean that the initial vaccination would cover all these little variants, so you wouldn’t have to worry.”

“We want a pan-coronavirus vaccine so you have it on the shelf to respond to the next viral pandemic,” Fauci said. “At the end of the day, you want to get a vaccine that covers everything.”

This dream of a universal vaccine is exactly what researchers at the US Army’s Walter Reed Army Institute of Research (WRAIR) have been working on for most of the past year. In December, the The US military announced that its pan-coronavirus vaccine, Ferritin Nanoparticle COVID-19 Vaccine (aka SpFN) had completed Phase 1 of human trials with positive results.

Dr. Kayvon Modjarrad, director of infectious diseases at WRAIR and co-inventor of SpFN, said defense one, “We are testing our vaccine against all the different variants, including the omicron”, the strain causing breakthrough infections, even in people who received booster shots.

SpFN still needs to undergo Phase 2 and 3 human trials, however, to test its efficacy and safety against current treatments, Modjarrad said.

We’ll share what we know about the Army’s COVID-19 vaccine, including how it works and when it might become available.

For more, here’s what we know about the omicron variant today and the evolving definition of what it means to be “fully vaccinated” against COVID-19.

What is the US Army’s COVID-19 vaccine?

The three vaccines currently licensed for use in the United States take two approaches to preventing COVID-19 infection: the use of Pfizer and Moderna vaccines mRNA to boost immunity, while the Johnson & Johnson vaccine uses a harmless rhinovirus to train the body’s immune system to respond to COVID.

The Spike Ferritin Nanoparticle COVID-19 vaccine, or SpFN, takes a third approach, using a harmless part of the COVID-19 virus to boost the body’s defenses against COVID.

SpFN also has less restrictive storage and handling requirements than Moderna and Pfizer vaccines, allowing it to be used in a wider variety of situations. It can be stored between 36 and 46 degrees Fahrenheit for up to six months and at room temperature for up to one month. according to military scientists. Pfizer’s vaccine requires an ultracold freezer (between minus 112 and minus 76 degrees F) for shipping and storage and is only stable for 31 days when stored in the refrigerator.

The army vaccine was tested with two injections, 28 days apart, and also with a third injection after six months.

Will the Army vaccine work against different strains of COVID-19 like omicron and other coronaviruses?

SpFN is being tested in humans against the omicron variant, according to Modjarrad, and has shown positive results.

Vaccines from Moderna, Pfizer and Johnson & Johnson all target the specific virus – SARS-CoV-2 – that causes COVID-19. But Army scientists designed their vaccine to be “pan-coronavirus,” meaning it could protect against future strains of COVID as well as other coronaviruses.

The Army’s SpFN vaccine is shaped like a 24-sided soccer ball. Scientists can attach the spikes of multiple strains of coronavirus to each of the different faces, allowing them to customize the vaccine for any new variants of COVID that arise.

“The accelerated emergence of human coronaviruses over the past two decades and the rise of SARS-CoV-2 variants, including the most recently omicron, underscore the continued need for next-generation preemptive vaccines that confer broad protection against coronavirus diseases,” Modjarrad said. said in a press release last month. “Our strategy has been to develop a ‘pan-coronavirus’ vaccine technology that could potentially provide safe, effective and long-lasting protection against multiple strains and species of coronavirus.”

When will the Army’s COVID vaccine be available?

No date has been set. SpFN successfully completed animal testing and completed Phase 1 of human trials in December, but has yet to complete Phase 2 and 3 of human testing, when its safety and efficacy are compared current vaccine options.

Normally, the completion of all three phases can take up to five years, but the urgency of the COVID-19 pandemic is accelerating the process. Moderna, Pfizer, and Johnson & Johnson vaccines, for example, have been tested, reviewed, and cleared by the Food and Drug Administration over the course of a year.

What happens next with the army’s SpFN vaccine?

Once the Phase 1 human trial data has been collected, analyzed and published, Phase 2 and 3 trials will begin. There is very little information so far on when or how these trials will take place or if the phases will overlap.
