WASHINGTON — Officials with the World Health Organization are looking ahead to 2021. They say they’re working to deliver 2 billion doses of a COVID-19 vaccine by the end of that year.
The WHO hopes the vaccine will be delivered to people across the globe, with about half of those doses expected to go to low- and middle-income countries. The new goal is part of a program launched in April that is comprised of four pillars focused on COVID-19. The pillars are tests, treatments, vaccines and health systems.
The top infectious disease expert in the country, Dr. Anthony Fauci, is warning that when the U.S. does have a vaccine for COVID-19, we still may not have full herd immunity. That’s when a sufficient proportion of a population is immune to an infectious disease. Fauci said there’s a lot of work to do on the vaccine.
“We are doing everything we can to show that it’s safe and that it’s effective. And it’s for the good of them as individuals and in society to take the vaccine,” he said.
Three vaccines are expected to be studied in large-scale clinical trials in the next three months.
