Britain's one vaccine dose plan could leave over-60s "seriously vulnerable" to coronavirus, scientists have warned. Downing Street's decision to delay second doses of the jab by up to three months in an effort to partially protect more people could pose major problems.
Experts working on the first real-world analysis of the Pfizer/BioNTech vaccine said results fail to show a efficacy at levels close enough to justify delaying a second jab.
Israeli scientist Professor Ran Balicer said preliminary data from 200,000 inoculated patients above 60 has left he and colleagues "very hopeful" that an end is in sight. What do you think about the vaccine rollout?
