Hundreds of people are rolling up their sleeves in countries across the world to be injected with experimental vaccines that might stop COVID-19.
President Donald Trump launched"operation warp speed" to get a vaccine in the U.S. by the end of the year.WASHINGTON -- Hundreds of people are rolling up their sleeves in countries across the world to be injected with experimental
As Dr. Anthony Fauci, the U.S. government’s top expert, put it: “You need more shots on goal for a chance at getting a safe and effective vaccine.” Fauci has cautioned that even if everything goes perfectly, 12 to 18 months to develop a vaccine would set a speed record — and January will mark a year since the National Institutes of Health began creating its own COVID-19 vaccine, now in trials with Moderna Inc.Depending how you count, there are between eight and 11 vaccine candidates in early stages of testing in China, the U.S., Britain and Germany — a collaboration between Pfizer Inc.
Most other vaccines in the pipeline aim to train the immune system to recognize a piece of the new coronavirus — mostly, the spiky protein that studs its outer surface. If study participants are holed up at home or live in areas where the virus has quit spreading rapidly, then too few may get sick for scientists to tell if the vaccine or social distancing was what protected them. The Oxford study, for example, will track about 1,000 people, half given the real vaccine. But the team plans a later-stage study with another 5,000 volunteers for a final answer and knows it might have to move to other countries.
In the U.S., the Trump administration is planning its own project dubbed Operation Warp Speed that will overlap studies of “different candidates that are made differently and act differently,” Birx said.
