A key feature was the lockdown in many cities in Hubei, which restricted much of the transmission to households, where the virus eventually burned out and prevented potentially hundreds of thousands of cases in other provinces.
Vaccine designers take first shots at COVID-19.
The race to develop a vaccine against the novel coronavirus is unprecedented in speed, scale, and scope; the "platforms" include inactivated and attenuated viruses, protein subunits, harmless viral vectors, messenger RNA, DNA, and viruslike particles.
HIV/AIDS: India Slashes Estimate of HIV-Infected People
After more extensive sampling, including a national household survey, the Indian government has come up with a new estimate that reduces the number of HIV-infected people by more than half.
