Within weeks, the UK could start to roll out 30 million doses of a new vaccine against the CCP virus, speeding up the country’s inoculation programme because it only requires one dose to be effective.

Both the Oxford/AstraZeneca and the Pfizer/BioNTech vaccines already being rolled out in the UK need two shots given weeks apart and provide relatively lower degrees of protection between first and second doses.
