Geneva, April 20 (RHC)-- The World Health Organization (WHO) has announced that there are three vaccines in the process of being clinically tested to see if they are effective in neutralizing COVID-19.

"Another 70 vaccines are in development," WHO Director-General Tedros Adhanom Ghebreyesus said at a press conference in Geneva.  Although three vaccines are being tested and dozens are in production, it will not be until the spring of 2021 that an effective drug will be available.

Once a vaccine meets all health standards, the WHO will promote its production and distribution worldwide.

"A WHO-backed project has been launched to exchange data on medical treatments that help to address COVID-19," WHO spokeswoman Margaret Harris explained.  An example of this is the Solidarity Program which was launched in March and involves over 900 patients in hospitals in 90 countries, among which are Argentina, Canada, France, Iran, Spain, and Thailand.

The WHO project uses four types of medicines and their combinations to tackle the virus and its resulting pneumonia.
