LONDON/GENEVA, Nov 17 (Reuters) - Pharmaceutical companies could be made to disclose prices and deals agreed for any products they make to fight future global health emergencies, under new rules that would govern a World Health Organization-backed pandemic accord reviewed by Reuters.The aim of the pact, commonly known as the pandemic treaty, is to prevent the next global health crisis from being as devastating as COVID-19 and improving the global response that left many of the world's poorest countries behind.During the pandemic, many deals governments made with pharmaceutical companies have been kept confidential, giving them little scope to hold drugmakers accountable.Mohga Kammal Yanni, policy co-lead for the People's Vaccine Alliance, said the pact could either break with the "greed and inequality" of COVID-19 and other diseases "or it could tie future generations to the same disastrous outcomes".Negotiations began on the pact in February and made an important step in July, when countries agreed to make the new agreement legally-binding despite earlier reservations from Washington."
