A Single-Dose COVID-19 Vaccine May Be Available Soon

COVID-19 vaccines continue to be administered around the world every day, but a new one might be here to speed up the process.

Johnson & Johnson announced Friday their new "single-shot" vaccine has shown positive results, and they intend to file for U.S. Emergency Use Authorization in early February.

The phase 3 trial of the vaccine posted what doctors are calling promising results, as it was 85% effective in preventing severe disease, and 66% effective overall in preventing moderate to severe COVID-19 across all regions studied.

The Pfizer and Moderna vaccines, both of which require two doses, showed over 90% effectiveness in preventing COVID-19, but Stoffels still calls the new vaccine's results "topline." 

"The potential to significantly reduce the burden of severe disease, by providing an effective and well-tolerated vaccine with just one immunization, is a critical component of the global public health response," said Stoffels. 

Johnson & Johnson says the vaccine's safety profile matches others using the same technology, with 9% of volunteers developing a fever.

If approved by the FDA, 100 million doses could be ready by June, with doses of the vaccine starting to be administered as early as late February per ABC News.
