US-Nurses' union president criticizes new CDC mask guidance

The National Nurses United union president is criticizing CDC guidance that vaccinated people can largely forego masks, saying it's confusing and could endanger health care workers. One problem? It relies on an honor system in which unvaccinated people still mask up. At least one local leader has already said such a system just isn't working. President Biden says there will be enough Covid-19 vaccine supply for every American adult by the end of this month, and his administration is pledging millions more vaccine doses to other countries on top of the 60 million already committed. We're also learning more about a coronavirus variant first detected in India that has now gone global. The B.1.617 is a "variant of concern," which means it could be more transmissible, cause more severe disease or evade tests and treatments. Experts think the variant is driving the recent waves of infection in India.
