Pfizer announced Wednesday that its COVID-19 vaccine is safe and strongly protective in kids as young as 12, a step toward possibly beginning shots in this age group before they head back to school in the fall.

Britain became the first country in the world to authorize a rigorously tested COVID-19 vaccine Wednesday and could be dispensing shots within days — a historic step toward eventually ending the outbreak that has killed more than 1.4 million people around the globe.
