A new "second generation" Covid booster vaccine has been approved for use in the UK.
The "bivalent" jab - which targets Omicron as well as the original strain of the deadly virus - is manufactured by Pfizer/Biotech, and follows a similar booster from Moderna that was given the green-light last month.
It was approved for over-12s by the Medicines and Healthcare products Regulatory Agency (MHRA).
