Nplate can be used to treat symptoms of acute radiation syndrome (ARS) which occurs after a person is exposed to a high dose of radiation from, for example, a nuclear accident or even a nuclear attack.
The Government purchased the drugs from the California-based pharmaceutical company Amgen.
The purchase comes following a speech last month in which Russian President Vladimir Putin vowed to protect Russia and its people with “all the means at our disposal.” He added that the threat was “not a bluff”.
However, HSS has denied that the purchase was related to the nuclear threat and claimed instead it was part of “ongoing” work concerning radiological security.
An HSS spokesperson told The Telegraph: “This is part of our ongoing work for preparedness and radiological security. It has not been accelerated by the situation in Ukraine.”
HSS is believed to have been working with Amgen and other pharmaceutical companies for years.
Yesterday, US President Joe Biden said that “Putin is not joking” regarding the use of weapons of mass destruction and warned that the world was at its closest to a nuclear “Armageddon” since the Cuban Missile Crisis in the 1960s.
He added: “I don’t think there’s any such thing as the ability to easily [use] a tactical nuclear weapon and not end up with Armageddon.”
The news comes as Putin faces pressure at home due to an unpopular mobilisation of hundreds of thousands of Russia men to fight in Ukraine.
With domestic pressure mounting and his forces ceding ground on several fronts in Ukraine, there are fears Putin may feel compelled to use a nuclear weapon, most likely in Ukraine.
The US has said that the consequences of using a nuclear bomb would be “catastrophic” for Russia, without elaborating.
Washington has also said that it has warned Moscow directly against the use of such a weapon.
