Theof COVID-19 has led to a surge of cases and hospitalizations and caused medical experts to discuss yearly COVID and . But what if there were a universal coronavirus vaccine that protected against omicron and all new COVID-19 variants?
Several institutions are researching, and major health organizations are speaking loudly about the need, but the US Army is the first to demonstrate positive trial results for a universal coronavirus vaccine.
Thethat its pan-coronavirus vaccine, the spike ferritin nanoparticle COVID-19 vaccine (aka SpFN) had completed Phase 1 of human trials. Publication of the results is expected in January, depending on the completion of the official data analysis.
Dr. Kayvon Modjarrad, director of infectious diseases at Walter Reed Army Institute of Research (WRAIR) and co-inventor of SpFN, told, “We’re testing our vaccine against all the different variants, including omicron,” the strain even in people who have received booster shots.
We’ll share what we know about pan-coronavirus vaccines and the Army’s COVID-19 vaccine, including how it works and when it could become available.

Why do we need a pan-coronavirus vaccine?
White House Chief Medical Adviser Dr. Anthony Fauci has recently touted the importance of a universal vaccine to protect against all COVID variants. At a, Fauci again stressed “the urgent need of a universal coronavirus vaccine.”
Fauci declared that, “innovative approaches are needed to induce broad and durable protection against coronaviruses that are known and some that are even at this point unknown. Hence, the terminology ‘pan-coronavirus vaccine.'”
The National Institute of Allergy and Infectious Diseases committed big to that goal in fall 2021,— Duke University, University of Wisconsin, and Boston’s Brigham and Women’s Hospital — to develop and research pan-coronavirus vaccines. for its universal “mosaic nanoparticle” vaccine.
In a Jan. 11 advisory statement on the omicron variant, thethat, “a vaccination strategy based on repeated booster doses of the original vaccine composition is unlikely to be appropriate or sustainable” and stressed the urgent need for a vaccine that offers long-lasting protection without boosters.
What is the US Army COVID vaccine?
The three COVID-19 vaccines authorized right now for use in the US take two approaches to preventing infection: The Pfizer and Moderna vaccines useto build up 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 portion of the COVID-19 virus to spur the body’s defenses against COVID.
SpFN also has less restrictive storage and handling requirements than the 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,. Pfizer’s vaccine requires an ultracold freezer (between minus 112 and minus 76 degrees F) for shipment and storage and is only when stored in a refrigerator.
The Army’s vaccine has been tested with two shots, 28 days apart, and also with a third shot after six months.
How does the Army vaccine work against COVID-19 and other coronaviruses?
The 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 protect against future strains of COVID as well as other coronaviruses.
The Army’s SpFN vaccine is shaped like a soccer ball with 24 faces. Scientists can attach the spikes of multiple coronavirus strains to each of the different faces, allowing them to customize the vaccine for any new COVID variants that arise.
“The accelerating emergence of human coronaviruses throughout the past two decades and the rise of SARS-CoV-2 variants, including most recently omicron, underscore the continued need for next-generation preemptive vaccines that confer broad protection against coronavirus diseases,” Modjarrad. “Our strategy has been to develop a ‘pan-coronavirus’ vaccine technology that could potentially offer safe, effective and durable protection against multiple coronavirus strains and species.”
When will the Army’s COVID vaccine be available?
No date has been set. SpFN successfully completed animal testing and wrapped Phase 1 of human trials in December, but it must still complete Phases 2 and 3 of human testing, when its safety and efficacy is compared to current vaccine options.
Normally, completing all three phases can take up to five years, but the urgency of the COVID-19 pandemic is speeding up the process. The Moderna, Pfizer and Johnson & Johnson vaccines, for example, were tested, reviewed and authorized by the Food and Drug Administration over the course of one year.
What happens next with the Army SpFN vaccine?
According to a WRAIR spokesperson, “researchers have devoted their full attention to analyzing the Phase 1 data and writing a report of the results.” The report could come in the next few weeks or even months.
After data from the Phase 1 human trials is published, Phase 2 and 3 trials will begin. There is very little information so far on when or how those trials will proceed or if the phases will overlap.
