COVID-19 vaccine

Russia was criticised for approving a Covid jab tested on only a few dozen people – but trials show Sputnik V offers high efficacy.
The vaccine rollout is progressing with encouraging speed. Here's how things could play out over the coming months.
Matt Hancock urged people in areas where the variant has been found to “take extra special precautions” under lockdown rules.
Ministers had wanted to have jabs offered to all residents and staff by January 31.
Representative Stephen Lynch received both doses prior to Inauguration Day, according to his spokesperson.
Scientists say lifting restrictions before enough people have had the jab will impact those in vulnerable groups with low take-up.
But the pharmaceutical giant's results showed it does not work as well as some two-shot rivals.
The manufacturer and PHE say there is strong data to reflect success in vaccinating older people.
