One hundred people were “one and done” Wednesday thanks to the latest grassroots effort to stay ahead of a new Covid-19 surge — as a church, a funeral home, and health center teamed up in Dwight.

The action took place at Immanuel Baptist Church at Chapel and Day streets.

Cornell Scott Hill Health Center set up a one-day Covid vaccination clinic there in collaboration with the church and Howard K. Hill Funeral Home.

It offered shots of the Johnson & Johnson vaccine — which, unlike other brands, requires only one injection, not two. One shot, and the person is done with the process.

Hill Health, the city and Yale have been organizing similar pop-up neighborhood clinics in a quest to outrun Covid-19 in addition to their regular standing vaccination sites. A new spike is producing growing numbers of cases, especially among younger people. At the same time, ramped-up vaccinations are leading to light at the end of the tunnel — with people everyday becoming largely immune to the deadly disease and ready gradually to resume pre-pandemic public life. The final big push begins Thursday as all people in Connecticut 16 and above are eligible for vaccinations.
