The majority of hospitalizations and deaths due to flu across the country have been among adults aged 65 and older.
In Dallas County, 18 flu-related deaths have been reported this season, according to WFAA.
Officials with the Jefferson County Health Department and UAB advised folks Wednesday evening during a press conference that we're in the middle of a major seasonal flu situation and many hospitals are seeing an uptick in patients suffering flu or flu-like symptoms.
At the same time, the number of flu cases is continuing to rise across Canada. The other type of vaccine - called "trivalent" because it covers three strains of flu - "unfortunately" doesn't cover that B strain.
"Our area hospitals and emergency departments are seeing an influx of patients that are seriously ill", said Dr. Mark Wilson, Jefferson County Health Officer.
Gunzenhauser stressed it is not too late to get vaccinated.
Last week it reported that as of December 30, there have been 13 reported cases of influenza-related intensive care unit admission.
"Even if it's not 100 percent effective, it still reduces the number of hospitalizations and can make the illness more mild if you do get the flu", said Jennifer Layden with the Illinois Department of Public Health.
"This season is a mirrored reflection of 2013-2014, which was one of the more serious flu seasons of the past decade".
Get vaccinated. The list of reasons to avoid vaccination is short (such as having a severe reaction to the vaccine in the past); and no, the standard injected flu vaccine can not cause you to get the flu.
Wischmeier says it's still worthwhile getting a flu shot, even though the season has been underway in full force. According to the Denton County Public Health Department, officials have 2,000 vaccine doses in stock. "You've got the body aches, the chills, the cough and the fever". People need to be allowed to stay home when they're sick, and they need to be allowed to stay home to care for their young children when they are sick.
Complications of flu can include bacterial pneumonia, ear infections, sinus infections and worsening of chronic medical conditions, such as congestive heart failure, asthma or diabetes.
