New Jersey health officials informed NJ Advance Media on Wednesday that forty-nine fully vaccinated individuals have died with COVID-19 through July 12. According to New Jersey Department of Health spokesperson Donna Leusner, over half of the patients who passed away had at least one underlying medical issue.

Of the 27 deaths in people who had underlying conditions, 17 had cardiovascular disease, seven had diabetes and nine had cancer or other immunocompromised conditions. Five had chronic lung conditions, three had chronic kidney disease, one had chronic liver disease and five others are listed as “other chronic diseases” according to the outlet.

Some of the individuals did have more than one underlying issue. Additional information includes “all of the deaths were people over age 50, with 3- of them over age 80.” Thirteen of the deaths occurred amongst individuals between the ages of 65 and 79, and six were between the ages of 50 and 64, said Leusner.

The Centers for Disease Control and Prevention (CDC) has reported that 48.8% of the total U.S. population has been fully vaccinated, and 56.3% have received at least one dose. The CDC also says there will be a small proportion of people who will still become ill with the virus even if they have been fully vaccinated.

“Vaccine breakthrough cases are expected” according to the CDC. “COVID-19 vaccines are effective and are a critical tool to bring the pandemic under control.” However, the CDC says “no vaccines are 100% effective at preventing illness in vaccinated people. There will be a small percentage of fully vaccinated people who still get sick, are hospitalized, or die from COVID-19.”
