Johnson & Johnson will join three other vaccines already approved for use in the UK - Astra-Zeneca, Pfizer and Moderna.
The Johnson & Johnson single-dose coronavirus vaccine has been approved for use in the UK, the medicines regulator has said.
The vaccine, developed by the company's pharmaceutical arm Janssen, has been shown to be 67% effective overall at preventing moderate to severe COVID-19, with some studies suggesting it also offers complete protection from admission to hospital and death.
The UK has ordered 20 million doses of the vaccine, which England's deputy chief medical officer, Professor Jonathan Van-Tam, has previously said could be used for hard-to-reach groups of people, where recalling them for a second jab is not always successful.
