SHANGHAI — Not a single country managed to meet the World Health Organization’s air quality standard in 2021, a survey of pollution data in 6,475 cities showed on Tuesday, and smog even rebounded in some regions after a COVID-related dip.
The goal is to make the vaccine – called Corbevax – available in other low- and middle-income nations across the globe to help prevent future variants of concern from forming.
“As long as we leave the southern hemisphere unvaccinated new variants of concern for us will emerge," said Dr. Peter Hotez, co-director of the Texas Children's Hospital Center for Vaccine Development and dean at Baylor's National School of Tropical Medicine. “The only way to stop it is to vaccinate the world and we think our [vaccine] is going to be a major contributor to that."
