Governor Parson Announces Activation of First Tier of Phase 1B of Missouri’s COVID-19 Vaccination Plan

Today, Governor Mike Parson announced the activation of Phase 1B – Tier 1 of Missouri’s COVID-19 Vaccination Plan. Federal partners have informed the state that they plan to significantly increase vaccine supply next week and those individuals 65 and older and those with comorbidities should be prioritized. This news allows the state to begin the process of activating Phase 1B tiers. The activation of Phase 1B – Tier 1 reflects the guidance the state has received from federal partners as well as information gathered from stakeholders across the state. Phase 1B – Tier 1 is activated today, and Phase 1B – Tier 2 will be activated on Monday, January 18. Tier 1 of Phase 1B focuses on protecting those who keep Missourians safe, including law enforcement, fire service, and public health professionals, among others.Tier 2 of Phase 1B focuses on protecting those who are at increased risk for severe illness, including individuals aged 65 and older and any adult with cancer, chronic kidney disease, COPD, or intellectual and/or developmental disabilities such as Down Syndrome, heart conditions, a weakened immune system due to organ transplant, severe obesity, pregnancy, sickle cell disease, or Type 2 Diabetes Mellitus. Missouri Department of Health and Senior Services (DHSS) Director Dr. Randall Williams issued a statewide health order today regarding the vaccination of individuals in Phase 1A, Phase 1B – Tier 1, and Phase 1B – Tier 2. The order outlines who can be vaccinated as part of the state’s determined phases and applies to those administering the federally-funded COVID-19 vaccines. To view the order, please see attachment. Although initial tiers within Phase 1B are being activated today and Monday, there are currently not enough vaccines for everyone included in these groups. As additional supplies arrive, this activation will allow for the greatest vaccine coverage where it is most needed. It will also allow vaccinators and organizations to continue planning effectively for future tiers and phases. Individuals in Phase 1A and Phase 1B – Tier 1 should work through their employer and/or association to access the vaccine. Individuals in Phase 1B – Tier 2 should contact their local pharmacy or health care provider or visit to learn when vaccines may be available and how to receive them. A list of vaccinators and regional vaccine implementation teams will be made available at on January 15. DHSS encourages employers and associations representing individuals in activated phases to use the list to connect with a vaccinator or regional vaccine implementation team in their area and make a plan for vaccinating their teams Based on reporting from providers, at least 27 percent of Phase 1A has received the first dose of the vaccine. This includes residents and staff of long-term care facilities and health care workers, including dentists, EMS, school nurses, and those working in hospital or clinic settings, among others. These individuals will continue to be vaccinated.  Missourians began receiving first doses of COVID-19 vaccines last month. More than 160,000 individuals have received an initial dose, and more than 22,000 have now been fully vaccinated with the 2-dose series. Vaccine supply continues to be the rate-limiting factor for vaccine administration throughout the state. State vaccine allocations are determined by Operation Warp Speed. Additional details on phases and tiers beyond Phase 1B – Tier 2 can be found at Public announcements will be made as later phases in the state’s vaccination plan are activated.A white sheet summarizing Phase 1B Tiers is attached.
