Needle-weary folks could have some relief when getting their COVID-19 vaccinations in the near future. That’s because a coronavirus vaccine pills is in the works through a handful of manufacturers.
In particular, IosBio—a Sussex, England-based company—is working with California-based ImmunityBio to create the tablet.
According to the New Zealand Herald, the tablets have been shown to be “highly effective” in clinical trials with monkeys. Trials on people, specifically Americans, began in January. The Irish Post reports that IosBio has also created an injection version of its vaccine, which is undergoing second and third trials.
Wayne Channon, chief executive of IosBio, told the Post that capsules would cut out healthcare workers in the administration of vaccines. That might be a boon to countries— like the U.S.— which are experiencing a shortage of healthcare staff to give the vaccine.
“With our capsule you wouldn’t need medical professionals to administer the vaccine,” Channon said. “You could send this out on Amazon Prime and have everyone vaccinated by Saturday.”
In the meantime, other companies are designing a nasal spray option.
The coronavirus vaccine pills are designed to withstand the heat and volatility of human stomachs, taking advantage of the mucous membranes of the intestinal tract. Channon told the Post that this method allows the vaccine to elicit mucosal immunity, “hitting the virus where it is.”
Another pill form of the COVID-19 vaccine from American manufacturer Vaxart began trials in September 2020. In late January, Vaxart announced that studies showed that hamsters that had received two doses of its oral vaccine had a “substantial reduction in lung inflammation as compared to unvaccinated hamsters.”
“The latest data from the SARS-CoV-2 Hamster Challenge Study reinforces our belief that our oral COVID-19 vaccine candidate shows great promise.” Andrei Floroiu, CEO of Vaxart, said in a statement. “Our oral vaccine could help fight the COVID-19 epidemic globally because it is stable at room temperature making it easier to transport, store, and administer than injectables. It may also appeal to those uncomfortable with injections.”
