Update December 16, 2021

The Missouri Department of Health and Senior Services updated the standing orders for the Janssen COVID-19 vaccine to indicate that either authorized mRNA COVID-19 vaccines (Pfizer or Moderna) are preferred over the Janssen COVID-19 vaccine for the prevention of COVID-19 in individuals ages 18 years and older due to the risk of thrombosis with thrombocytopenia or Guillain-Barre (GBS) following vaccination. Clients medically unable to receive the mRNA COVID-19 vaccine or who would otherwise not be vaccinated against COVID-19 may request the Janssen vaccine, and a CCPHC nurse may determine if the client is eligible for the vaccine.
