The state is working with Griffin Health to provide some last-minute vaccinations before the holiday.

Gov. Ned Lamont joined local leaders Wednesday for one last vaccination push before the holiday weekend.

A vaccine clinic was held by Griffin Health at the train station Wednesday.

Clinics are also being held at the New Haven train station and Bradley Airport, as Connecticut residents travel amid rising COVID-19 numbers.

"Our infection rate has more or less doubled over the last three weeks. Today we're at 3.7%, we've got up to 300 hospitalizations," said Lamont.

Doctors with Yale Medicine say the Pfizer vaccine drops to 80% effectiveness after four to six months.

Dr. Sharon Stoll says it's especially important to get that immunity topped off as people gather indoors for cold-weather holidays with vulnerable family members.
