The wealthy Bill & Melinda Gates Foundation called Wednesday for global cooperation to ready COVID-19 vaccines for seven billion people, while offering $150 million toward developing therapeutics and treatments for the virus. While it is likely to take as many as 18 months to develop and fully test a safe coronavirus vaccine, global authorities and businesses need to start now on plans to manufacture it, said foundation chief executive Mark Suzman. “When you are dealing with a novel pathogen like COVID-19, as and when we get to identifying a successful vaccine, we are going to need billions of doses.”
