Ministers have agreed [to] a secrecy clause in any dispute with the drugs manufacturer Pfizer over Britain's Covid vaccine supply. Large portions of the government's contracts with the company over the supply of 189m vaccine doses have been redacted and any arbitration proceedings will be kept secret. The revelation comes as Pfizer is accused by a former senior US health official of "war profiteering'' during the pandemic. Tom Frieden, who was director of the US Centers for Disease Control and Prevention under Barack Obama, said: "If you're just focusing on maximising your profits and you're a vaccine manufacturer ... you are war profiteering." Zain Rizvi, research director at Public Citizen, a US consumer advocacy organisation which has examined Pfizer's global vaccine contracts, said: "There is a wall of secrecy surrounding these contracts and it's unacceptable, particularly in a public health crisis." Rizvi said the UK needed to explain why it had agreed to secret arbitration proceedings. He said: "It's the only high-income country we have seen that has agreed to this provision. It allows pharmaceutical companies to bypass domestic legal processes." While AstraZeneca agreed to sell its vaccine at cost during the pandemic, Pfizer wanted to secure its profits. The Pfizer/BioNTech vaccine ... will be one of the most lucrative drugs in pharmaceutical history. One biological engineering expert [claims] the Pfizer vaccine costs just 76p to manufacture for each shot. It is reportedly being sold for £22 a dose to the UK government.
