The New Jersey Department of Health began releasing details of breakthrough cases of COVID-19 this week — cases among people who have been fully vaccinated but test positive for the virus. Health officials credit that low rate to vaccines proving to be 99.9% effective. According to the health department, between January and June 28, out of 4.5 million fully vaccinated people 3,500 contracted COVID-19, a rate of 0.08%. Eighty-four were hospitalized and 31 died.
Dr. Ed Lifshitz, director of New Jersey’s communicable disease service, said that because people with existing health problems are more likely to be susceptible, “certainly that’s one more reason why we encourage everybody to be vaccinated.”
