The ostensibly sarcastic comment wasn't funny to federal health officials.
"I don’t know if [Jackman] really meant that vaccination was not a good thing to do, but each year millions become ill with influenza, more than 200,000 may be hospitalized, and between 3,000 and 49,000 will die," a CDC spokesman told celebrity news site TMZ.
"The first and most important step in protecting against the flu is to get a flu vaccine each season," the spokesman added.
As of Friday, the flu had reached epidemic levels in the United States. Health experts suggest that everyone get a flu shot. This year's vaccine is 62 percent effective, according to the CDC.
