  • Breakthrough cases of the Delta Variant in Provincetown, Massachusetts proved to be sobering as 75% of cases were vaccinated. Studies show that vaccinated individuals carried the same amount of viral load as unvaccinated individuals. Yet still, vaccination is still the best way to end the pandemic.

  • “People should be reassured that if they are fully vaccinated that they are very likely, highly likely, to be protected against severe or critical illness, the kind of illness that would cause them to be hospitalized or killed by this virus,” said Paul A. Offit, a vaccine expert at Children’s Hospital of Philadelphia. “Vaccines save your life.”
