States skeptical of Biden's Covid-19 vaccine plan as they await the missing details

State officials are skeptical that President-elect Joe Biden can meet his goal of 100 million coronavirus shots in his first 100 days, with a week to go before his start date and a slew of unanswered questions still swirling around his plan.

Multiple state officials and sources familiar with the Biden transition team's outreach told CNN in recent interviews that they are unclear on major details of the Biden team's plans -- including those for mass vaccination sites, vaccine supply issues and funding for local governments. CNN previously reported that the incoming administration is still deliberating major details of its national vaccination plan. Biden is expected to unveil his plans for vaccines on Thursday, along with a major Covid relief package that his advisers have told allies in Congress is expected to be in the ballpark of $2 trillion, according to two people briefed on the deliberations.
