Why is Pfizer sharing its COVID-19 pill but not its vaccine?

As big pharma refuses to share its COVID vaccine secrets, the WHO hires a South African lab to crack the mRNA code.

Pfizer’s chief executive Albert Bourla says his COVID-19 oral antiviral drug is “a real game changer”. He claims the pill cuts the risk of hospitalisation and death by 89 percent.

But unsurprisingly campaigners are already raising concerns that the rich world will once again corner the anti-viral market. Dr Githinji Gitahi, the chief executive of Amref Health Africa, explains what needs to be done for the equitable distribution of vaccines.
