Check back here and on our Facebook page for updates and for information about when we will begin scheduling appointments. 

Bivalent Vaccine Now Available

The updated bivalent COVID 19 vaccine is now being offered by the Cass County Health Department. This change comes as COVID 19 continues to develop more strains such as the Omicron strain. The bivalent vaccine was designed to offer protection against both the Omicron BA.4/BA.5 variants as well as the original SARS-CoV-2 variant. The Moderna bivalent COVID 19 vaccine is being offered to those 18+ as a single booster. The Pfizer bivalent COVID 19 vaccine is being offered to those 12+ as a single booster.
