Monthly Yearly Lamont: With thousands fewer J&J COVID vaccine doses, CT will have to make due for a time Dave Altimari :: CT Mirror The West Hartford/Bloomfield Health District opened a new mass vaccination clinic in an abandoned Shop Rite grocery store on the West Hartford/Hartford town line. Some 400 people were vaccinated there on Thursday, April 8, 2021. While manufacturing problems will delay thousands of Johnson & Johnson COVID-19 vaccine doses from reaching Connecticut in the coming weeks, Gov. Ned Lamont remained optimistic Thursday that a majority of residents will be at least partially immunized against the coronavirus by the end of April.
