The UK has signed deals to buy a further 4.25 million courses of antiviral Covid pills for the NHS.
The two new contracts are for 1.75 million additional courses of Molnupiravir and 2.5 million additional courses of Paxlovid.
They will be available from early next year and are both expected to be effective against Omicron.
The tablets will be used to either treat those who are infected with the virus or sometimes protect exposed individuals from becoming infected.
The government is urging all over 50s and most vulnerable to sign up to the national study as soon as they test positive for Covid.
Announcing the deal, Health Secretary Sajid Javid says: “This is a mammoth deal for the UK government and for patients across the country that are set to benefit from these antivirals over the coming months.”
