Britain could start distributing a coronavirus vaccine by Christmas, the deputy chief medical officer has said as he and Boris Johnson hailed “a significant scientific breakthrough” – but cautioned the public of hurdles to come.
Prof Jonathan Van-Tam said news that large-scale trials showing the Pfizer/BioNTech candidate to be 90% effective was “very exciting” but warned that no vaccine would come soon enough to stop significant restrictions on public life during the second wave.
