Europe's drug regulator is expected to rule on the safety of the Johnson & Johnson Covid-19 vaccine after fears it could be linked to extremely rare blood clots, while India said it will make shots available to all adults as it battles a terrifying wave of infections.
The United States is also expected to announce its decision on the single-shot J&J vaccine by Friday, as nations around the world try to accelerate their roll-outs and revive their pandemic-ravaged economies.
The European Medicines Agency is due to hold a press conference from Amsterdam, after reviewing four cases - one fatal - of rare blood clots reported among people who got the J&J shot.
