A new Covid vaccine has been approved for use in the UK by regulators.
It is manufactured by Valneva, using more traditional technology - similar to how polio and flu shots are made.
It contains a whole copy of the virus which has been inactivated, so that it can't cause the disease but does teach the body how to fight it.
The UK was due to receive 100 million doses of the jab, but the government cancelled the deal in September due to a "breach of obligations".
The French company strenuously denied the government's accusation.
Dr June Raine, chief executive of the UK's Medicines and Healthcare products Regulatory Agency, said the approval followed "a rigorous review of the safety, quality and effectiveness of this vaccine".

Inactivated viral vaccines tend to have poorer efficacy, against symptomatic infection (which relies on antibodies binding to the receptor binding domain(s) of the spike protein).
But there is an advantage that it provides some additional (mostly T-cell) immunity against viral components other than the spike protein which can increase efficacy against severe disease if used in combination with one of the other vaccines.
