New vaccine appointment system to debut next week in NH KATHY McCORMACK, Associated Press FacebookTwitterEmail CONCORD, N.H. (AP) — New Hampshire is planning to go live with its new COVID-19 vaccine appointment system on March 17. Before that day, instructional videos will be available for the state-created Vaccine & Immunization Network Interface — VINI for short. They will cover the main parts of the process: screening and registration, scheduling, receiving the vaccine, and a verification message. VINI is replacing the CDC's Vaccine Administration Management System, or VAMS, which New Hampshire originally signed up to use. Thousands of people struggled to book their booster shots within the recommended time using that system.
