Former Biden, Trump advisers renew push to delay second Covid vaccine

As Covid-19 cases spike and coronavirus variants continue to spread, the Biden administration is facing renewed calls to delay second vaccine doses and blanket more of the U.S. population with an initial shot.

Advocates of a strategy focused on first doses include Democratic and Republican senators, Trump administration surgeon general Jerome Adams, and at least four physicians or epidemiologists who advised President Biden on pandemic response issues prior to his inauguration, including the prominent surgeon and author Atul Gawande.
