Connecticut Department of Public Health releases data on COVID-19 vaccine breakthrough cases, highlighting the vaccine’s effectiveness against the virus

As Connecticut surpasses the 50% mark for residents ages 16 and over who are now fully vaccinated, the Connecticut Department of Public Health today released data on vaccine breakthrough cases, which clearly show that the COVID-19 vaccines are highly effective at fighting the virus.

So-called “vaccine breakthrough cases” occur when a person who has completed their vaccine series becomes infected with the virus. The data shows that cases of COVID-19 in fully vaccinated individuals are rare, with less than 0.1% of Connecticut’s fully vaccinated persons being reported as having contracted the virus.

Of the 1,467,189 persons in Connecticut who have completed their vaccine series, 242 have been confirmed as contracting COVID-19. Of those, 109 (45%) had no symptoms of the disease. Three deaths have occurred among the 242 vaccine breakthrough cases. All three individuals were confirmed to have had underlying medical conditions and were in the age groups 55-64 (1), 65-74 (1), and 75+ (1). Nationally, the CDC has reported a total of 132 vaccine breakthrough deaths.

“The main takeaway is that COVID-19 vaccines are highly effective and cases of infection after a person is fully vaccinated are very rare,” Connecticut Public Health Acting Commissioner Dr. Deidre Gifford said. “The best protection against severe illness, hospitalization, and death from COVID-19 is vaccination, and I strongly urge all eligible Connecticut residents who have not yet gotten vaccinated to do so.”

In addition to the overall number of breakthrough cases, the Department of Public Health also announced that of the 242 breakthrough cases:

  • 159 cases (65.7%) were among women;
  • 58 cases (24%) occurred among persons living in congregate settings (i.e. nursing homes, assisted living facilities); and
  • 32 cases (13.2%) have been hospitalized.

“The vaccine is our most powerful tool against COVID-19, but these rare instances of infection after vaccination are a reminder that no vaccine is 100% effective,” Acting Commissioner Gifford said. “As long as we continue to see cases of COVID in Connecticut, it is important to continue the use of the other tools at our disposal – masking when indoors and in large outdoor crowds, hand washing, social distancing, and limiting gathering sizes when vaccination status is unknown.”
