The U.S. Army will begin testing among adults volunteers an army-developed Covid-19 vaccine that researchers say can protect against a variety of coronavirus variants.
Army doctors plan to test the protein-based shot on Tuesday in as many as 72 adults ages 18 to 55 at the Walter Reed Army Institute of Research in Silver Spring, Md., The institute said. The team will test whether the vaccine safely induces the desired immune response in subjects.
The initial results of the study could become available by midsummer. If the data are positive, the military is likely to try to join a drug company to further test and develop the vaccine, said Kayvon Modjarrad, director of the institute’s new infectious diseases department.
The experimental shot is among dozens in development, many of which aim to improve the available shots. According to BioCentury, which tracks efforts, there are 229 trials of human vaccine underway.
Army researchers say their vaccine was protective in studies of monkeys exposed to coronavirus.
