The illnesses occurred in both children and adults, from two Southeast Michigan counties, but we don’t yet know exactly which ones yet.

“The cases themselves were flu strains that were in the flu shots this year, so that’s a really good indicator that what is in the vacine is going to protect you from what we are already seeing circulating in the environment,” she said.

“The reason it’s so important to get a flu shot now, is because now that we know and have confirmed cases of the flu in Michigan it takes about two weeks for the flu vacine to fully protect you from getting the flu.”

Michigan’s level of flu activity is considered sporadic right now, but that could change at any time, so state health officials say protect yourself, now the time to get vaccinated.
