We begin with the latest on the global race to develop an effective vaccine against the coronavirus.
Nine leading drugmakers around the world have issued a joint statement vowing to put safety first as their clinical trials move forward.
The companies include Britain-based AstraZeneca and U.S.-based Pfizer.
The declaration was issued on Tuesday. The companies promise to make the safety and well-being of vaccinated people their top priority.
They say they'll only seek approval or emergency-use authorization after safety and effectiveness are demonstrated through a phase 3 clinical study.
Coronavirus vaccines currently under development haven't yet passed the final phase of clinical trials.
But China and Russia have already authorized the use of some vaccines. And U.S. authorities have suggested they too will approve some vaccines for emergency use.
The race for a vaccine has become highly competitive, as governments see it as a way to boost their own standing.
