Watch: Boris Johnson says 'we'll have to get used to idea' of autumn booster jabs
The prime minister has raised the prospect of people getting a coronavirus vaccine "booster" jab in the autumn.
"I think we're going to have to get used to the idea of vaccinating and then revaccinating in the autumn, as we come to face these new variants," he told the Commons during PMQs.
It comes after a study suggested that the Oxford/AstraZeneca vaccine may offer limited protection against mild disease caused by the coronavirus variant discovered there.
However, researchers say it will protect against deaths and severe disease.
A US study found that the Pfizer/BioNTech jab is effective against the variant.
Approximately 170 cases of the South Africa variant have been detected in the UK so far.
It carries the E484K mutation which experts have suggested may be better at evading the human immune response.
