COVID-19
A single-shot COVID-19 vaccine from Johnson & Johnson has shown very strong results in early clinical trials, potentially providing a significant boost to U.S. vaccination efforts.
The vaccine produced an immune response of all 805 clinical trial participants within two months of inoculation, according to results published Jan. 13 in the New England Journal of Medicine.
The Johnson & Johnson vaccine also would be hardier than either of the already approved vaccines because it relies on DNA technology rather than messenger RNA to prompt an immune system response.
The new vaccine is made up of a deactivated cold virus into which scientists cut-and-paste a genetic version of the “spike” protein used by the coronavirus to infect cells. The immune system recognizes the incomplete and harmless coronavirus protein as an invader and mounts a response, learning how to ward off any future infections from the actual coronavirus.
