Can Biden pull off 100 million doses in 100 days? Plus more virus questions answered

News outlets have been parsing President Joe Biden’s promise of 1 million COVID-19 shots a day for his first 100 days. Depending on the outlet, the goal is too ambitious, or too modest, or doable but difficult, or already stirring disagreements within Biden’s pandemic response team.

Even if that 100-day goal is achieved, it will be only the beginning. Experts estimate that 60% to 70% of the population would need to be vaccinated to extinguish the spread of the coronavirus. Anthony Fauci, who is being retained by Biden as the government’s top infectious disease adviser, recently raised his estimate to 80% to 90%. Meanwhile, the COVID-19 death toll is 410,000 and counting.
