Many countries are not officially reporting the number of health and care workers who have died of Covid, and the WHO estimates the real figure is at least 115,000 - and potentially much higher.
There are around 135 million health and care workers around the world, according to the International Labour Organization.
The latest data reported to the WHO from 140 countries suggests just one in eight is fully vaccinated, the vast majority in richer nations.
WHO's Regional Office for Africa, confirmed that 2.4 million health workers across 38 countries have had at least one dose of a vaccine - but another 66.2 million doses are needed to ensure all health and care workers in the region are double-jabbed.
Covid vaccines remain scarce internationally, particularly in lower-income countries.
