WASHINGTON — Army scientists are testing whether their new COVID-19 vaccine candidate, which entered human trials this week, can serve as a universal booster shot for all other available coronavirus vaccines.
Nearly 20% of Americans have already been fully vaccinated against COVID-19 using one of three authorized vaccines.
But with public health experts and government officials anticipating the need for booster shots down the line, scientists at the Walter Reed Army Institute of Research are examining whether their vaccine candidate can “mix and match” with the others to enhance and prolong protection.
