These estimates are pending the federal procurement of 600 million vaccine doses by the end of July.
"I can estimate that we'll be in phase 1B until the end of April, Phase 1C until approximately the end of May then we'll be in Phase 2 meaning everyone is eligible by June and we'll reach everyone who wants the vaccine by the end of July," said Farley.
Also promising news, the one-dose Johnson & Johnson vaccine could arrive in Philadelphia by March 1.
Farley said there were 103 new positive cases of the coronavirus reported Tuesday.
