(WXYZ) - University of Michigan Health System is issuing a vaccine reminder following severe cases of the flu in young, healthy people.
More than a dozen adults and kids are on life support at the University of Michigan's hospitals because of the flu.
Most of them have the H1N1 strain of the flu.
Dr. Matthew Davis says "When influenza is very severe, it's typically because it has attacked the lungs so severely and attacked the circulatory system that people are having health problems that are making it hard for them to breathe properly, get enough oxygen in and in some cases get enough blood to all the parts of the body that need it."
The increase in such severe cases of the flu has led UMHS to issue temporary visitor restrictions in order to protect vulnerable patients from unnecessary exposure to the flu.
So, is it too late to get vaccinated? Dr. Davis says absolutely not. He says getting vaccinated is your best protection against the flu.
"The benefits of the vaccination typically begin two weeks after the shot or nasal spray. That means we have time for people to get their shot and be protected from the flu this season," says Dr. Davis.
