No it isn't, jollyg That is an urban myth.
"To set the record straight: Eighty percent of WHO's budget now comes from governments. For the two-year budget period 2010-11, 53 percent of the voluntary contributions came directly from governments that chose to go beyond what their annual dues require; 21 percent came from other UN bodies (such as UNICEF, UNDP, and UNAIDS) and other multilateral bodies (such as the Global Alliance for Vaccines and Immunization); 18 percent from philanthropic foundations (such as the Bill & Melinda Gates Foundation, the UN Foundation, and the Rockefeller Foundation). Of the remainder, seven percent came from nongovernmental organizations, by far the largest of which was Rotary International for work on polio eradication."
"For the entire year, just one percent came from private industry. And roughly half of that comprised a specific donation from local organizations in Japan to finance costs of a WHO office in Kobe. The other half came from pharmaceutical companies that directed their funds toward neglected and tropical diseases." www.foreignaffairs.com/articles/2011-11-18/setting-record-straight-who-funding
