The White House Coronavirus Task Force is calling on states to push ahead with vaccinations, particularly among senior citizens, according to a new report obtained by ABC News.

States should not "delay the rapid immunization of those over 65 and vulnerable to severe disease," the report said. It also recommended creating vaccination sites with EMTs on hand to deal with any allergic reactions and using nursing students to help with the rollout.

"No vaccines should be in freezers but should instead be put in arms now; active and aggressive immunization in the face of this surge would save lives," the memo said.
