Mayor Lori Lightfoot and Cook County Board President announced the decision in a joint statement, saying that the city and county are not receiving enough doses of the vaccine to allow them to expand eligibility along with the rest of the state in a decision Gov. J.B. Pritzker announced the day before. "Our goal is to get as many people vaccinated as quickly and efficiently as possible. That said, our greatest challenge in doing so is the very limited supply of vaccine we are receiving. While we are making progress every day with vaccinating people in 1a and 1b, at this time we are not being supplied with enough doses that would allow us to expand eligibility in these phases," the statement reads.
