A new strain of influenza is causing concerns as flu season ramps up in NJ.

Subclade K is a mutated strain of influenza that may have some influence on the effectiveness of the current vaccine.

Doctors still urge everyone to receive a flu vaccine as this new strain is just one of three that typically circulate during the season.

Last year's flu season saw the highest rate of hospitalizations in 15 years, including at least 280 children dying from the disease.
