Chinese researchers plan to study using a Covid-19 vaccine from CanSino Biologics as a booster shot for people who have already been inoculated with other vaccines, clinical trial registration data showed.
Reuters reports a total of 300 healthy adults aged 18-59 years will be recruited for the trial.
Some participants who have received either one or two doses of inactivated vaccine will receive a booster shot from CanSinoBIO. The rest will be given the Sinovac vaccine as a booster for comparison.
