Pfizer Inc and BioNTech Se plan to give volunteers who received a placebo in its Covid-19 vaccine trial an option to receive a first dose of the vaccine by 1 March 2021, while staying within the study, Reuters reports.

The trial's Vaccine Transition Option allows all participants aged 16 or older the choice to discover whether they were given the placebo, and for participants who learn they received the placebo, to have the option to receive the investigational vaccine while staying in the study," the companies said on their website.
