Community Bulletin Board: Criterion Sentinel (for April 28) Keep Middlesex Moving has developed a transportation finder to help seniors find a ride to their COVID-19 vaccination appointments. The tool allows users to see what transportation options are available at almost all of the 40-plus vaccination sites in Middlesex County. The Middlesex County Regional COVID-19 Vaccine Mega-site, operated by RWJBarnabas Health, is seeking volunteers to assist in the efficiency of the registration and vaccination process and help visitors feel comfortable. Volunteers of the mega-site, located at the New Jersey Convention & Expo Center, 97 Sunfield Ave., Edison, will greet patients and visitors; perform temperature screenings; direct patients through various steps of the vaccination process; provide education materials; and assist with maintaining the registration area and supplying vaccination stations.
