The Advisory Committee on Immunization Practices (ACIP) guidance and recommendations regarding COVID-19 vaccination phases can be found here. Currently, we are ensuring that all of phase 1A is vaccinated as recommended by the ACIP. There are times in which you may see an overlap of phases. One phase will not necessarily be completed before moving onto another phase. This is referred to as “gating.” Recently ACIP gave additional guidance on phase 1B and 1C. MDHHS updated their prioritization guidance to reflect this. MDHHS has expanded and moved to recommending all those 65 years and older be vaccinated with COVID-19 vaccine. We have expanded further to ensure all those who are higher risk due to age are vaccinated. This still falls within the guidance provided by ACIP but altered slightly the order at which people are being vaccinated.
