AstraZeneca reiterated on Wednesday that its Covid-19 vaccine was very effective at preventing the disease, based on more recent data than was included when the company announced the interim results of its U.S. clinical trial on Monday.
The company said in a news release that its vaccine was 76 percent effective at preventing Covid-19. That is slightly lower than the efficacy number that the company announced earlier this week.
Provisional data compiled by the World Health Organization (WHO) from 84 countries indicates that an estimated 1.4 million fewer people received care for tuberculosis (TB) in 2020 than in 2019 - a reduction of 21% from 2019.
In the group of 10 high-burden countries with the largest reported shortfalls compared with 2019, the overall shortfall was 28%. With many people with TB unable to access care, WHO estimates that half a million more people may have died from TB in 2020 alone. TB remains one of the world’s top infectious killers.
