China is among three additional countries to have signed on to a global initiative that aims to ensure fair and equitable access to a COVID-19 vaccine once developed, the World Health Organization (WHO) reported on Friday. The country, together with South Korea and the tiny Pacific island of Nauru, joined the COVAX Facility this week, bringing the total number of participating nations and economies to 171, WHO chief Tedros Adhanom Ghebreyesus announced during his regular media briefing on the pandemic. "The world is eagerly anticipating the results of trials of vaccines against COVID-19, which are needed for WHO authorization", said Tedros. "Once we have an effective vaccine, we must also use it effectively, and the best way to do that is by making sure it's available to all countries equitably through the COVAX Facility." The global mechanism will work to deliver two billion doses by the end of next year. It currently has the largest portfolio of potential vaccines, with several in advanced human trials. WHO was asked about the impact of China's participation. "The more countries that participate in the COVAX Facility, the greater opportunity of being able to roll out vaccines as rapidly as possible, as fairly as possible, to reduce the risk of severe COVID disease globally", said Dr. Bruce Aylward, senior adviser. He added that details on China's enrollment "(are) still being worked out", with specific information anticipated early next week. Notably, both the United States and Russia have not so far signed on. WHO has also welcomed the announcement this week that vaccine developer Moderna will not enforce patent rights over its COVID-19 shots during the pandemic. Tedros expressed appreciation for "this act of solidarity", which aligns with another initiative for sharing scientific knowledge, data, and intellectual property in efforts to beat back the disease. The COVID-19 Technology Access Pool (C-TAP) was launched in May and is described as a "one-stop-shop" for affordable access to technology. It draws on existing mechanisms such as the UN-backed Medicines Patent Pool, which expands access to treatments for HIV and hepatitis for low and middle-income countries. — UN news
