The Nation’s Top 10, Bottom 10 States in Vaccination, Infection Rates


This Story's Health Experts


It’s not over yet, but Connecticut continues to withstand COVID-19 with a not-so-coincidental combination of vaccination rates that rank among the nation’s highest and a test positivity rate that now ranks among the nation’s lowest.

The state has the second-highest vaccination rate (69.62 percent) and fourth-lowest test positivity rate (2 percent), according to the latest updates Thursday morning.

“Our vaccination rate has played a significant role in reducing at least the mortality in the hospitalizations we are seeing right now,” says Dr. Ajay Kumar, Hartford HealthCare’s Chief Clinical Officer. “But in terms of reducing the positivity, one of the things I like to believe is that Connecticut has generally been a bit more compliant with masks and social distancing than many other states in the country. I’m really proud of our state and how we’ve managed the pandemic.”

What about the rest of the country?

Here, in Top 10 compilations, are states with the highest and lowest vaccination rates and infection rates. Some correlations need no explanation: Idaho, with a stunning 62.8 percent infection rate, also has the second-lowest vaccination rate (42.53 percent). New Jersey, with the ninth-highest infection rate (16 percent) despite having the sixth-highest vaccination rate, requires a deeper look into the vaccine’s effects. In the state’s first report on breakthrough cases last month, only 6 percent of cases and 5 percent of hospitalizations were among vaccinated residents.
