A COVID vaccine for all variants? Army hopes pandemic is a game-changer


The military’s COVID vaccine began human clinical trials in March 2021.

A new Covid-19 vaccine hopes to protect against all existing and future coronaviruses, and this is not to Pfizer, Modern or any pharmaceutical company. The US military announced the first results of a vaccine developed by the Walter Reed Army Institute of Research that includes defense against the now dominant omicron variant of COVID-19 — strain causing breakthrough infections in people who have had two or more injections of the vaccine.

Vaccines have been shown to be very effective in preventing serious illness and death from COVID-19. Recent data from January 5 from Washington state shows people over 65 are 13 times more likely to be hospitalized and 15 times more likely to die from COVID-19 compared to those over 65 who have received two doses of Moderna or Pfizer vaccines or one dose of Johnson & Johnson.

As the omicron variant spreads around the world and epidemics occur among “fully vaccinated“Let governments and medical experts scramble, an effective military vaccine for existing and future COVID-19 variants could become a pandemic solution to stop reinfection with coronavirus mutations.

The military isn’t just shooting COVID-19. Scientists are designing the vaccine to be suitable for all viruses in the coronavirus family, future and past, including SARS, a virus that infected more than 8,000 people in its last outbreak in 2003.

We’ll share what we know about the military’s COVID-19 vaccine, including how it works and when it might be available. Here is the current state of federal vaccine mandates, what we know about omicron today and eight mask myths put people in danger today.

The three vaccines currently licensed for use in the United States take two approaches to protect against infection with COVID-19. Pfizer and Moderna vaccines use MRNA to boost immunity to the disease, and the Johnson & Johnson vaccine uses a harmless virus (not the one that causes COVID-19) to train the body’s immune system to respond to COVID.

The U.S. military vaccine – officially named the Spike Ferritin Nanoparticle (or SpFN) COVID-19 vaccine – takes a third approach, using a harmless portion of the COVID-19 virus to boost the body’s protection against COVID.

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

The vaccine was tested with two injections, 28 days apart, and also with a third injection after 6 months.

Vaccines from Moderna, Pfizer, and Johnson & Johnson all target the specific virus – SARS-CoV-2 – that causes COVID-19. Army scientists are going one step further and designed their vaccine to be a “pan-coronavirus,” which means they plan to use it against a variety of coronaviruses, including new strains of the virus as they develop. ‘they emerge.

Dr Kayvon Modjarrad, founding director of the Emerging Infectious Diseases Branch of the Walter Reed Army Institute of Research, said army time, “We designed and positioned this platform as the next-generation vaccine, a vaccine that paves the way for a universal vaccine to protect not only against the current virus, but also against future variants, stopping them in their tracks before. that they cannot cause another pandemic. “

Although the army’s vaccine has not been directly tested on the omicron variant, scientists working on the vaccine have said that its protection has shown promise against omicron in the lab using samples of the vaccine. ‘human trials.

No date has been set. The vaccine is currently undergoing clinical trials to determine how safe and effective it is. Normally, the completion of all three phases of a clinical trial can take three to five years, but the emergency of the COVID-19 pandemic could speed up the process. Existing COVID vaccines authorized by the Food and Drug Administration have been tested, reviewed and authorized within a year.

Once the data from the phase 1 human trials have been formally collected, analyzed and published, the phase 2 and phase 3 trials will begin. There is very little information to date on when or how these trials will unfold or if the phases will overlap.
