Provincetown Becomes Test Case For Vaccines And Delta Variant

The number of cases linked to a Fourth of July COVID cluster in Provincetown continues to grow.

The latest data from the Barnstable County Department of Health and Environment show more than 900 people have tested positive for the coronavirus there, many of them fully vaccinated.

Health officials suspect the highly contagious delta variant is to blame.

The cluster has pushed the seaside town into the spotlight and is providing health officials with first of its kind data on vaccines and an evolving pandemic.
