According to the Oklahoma State Department of Health, two people have died from the flu within the last week. It can cause mild to severe illness.
Doctors say a typical flu season in Oklahoma usually runs from October to May.
There was a similar issue three years ago when the vaccine was just 13% effective. On Oct. 3, it was announced that Oxford University's Jenner Institute and Vaccitech, a biotech company, are developing a potential universal flu vaccine.
It generally takes about two weeks after the vaccine to build up immunity to the flu virus, so Health Department urges the public to get the shot soon, particularly if they will be seeing babies too young to receive the vaccine.
For many, the flu vaccine is covered under some form of insurance or through Medicare Part B - and often with no out-of-pocket cost. That could eliminate the need for people to get new flu shots each year.
Though researchers are working hard behind the scenes to develop more effective vaccines, you should still aim to be proactive about your health.
Flu vaccines are created to protect against the most common flu viruses. "We're seeing now that the vast majority of the strains that are early-circulating now right now in the United States...are this H3N2, which historically is always the worse influenza, for example, than an H1N1", Fauci said.
Myth 2. You can't spread the flu when you don't feel sick. You should also wash your hands, and be careful of items like door knobs and sell phones which collect bacteria.
Medical professionals hope this doesn't discourage people from getting their flu shots. Staying healthy during the winter can be a challenge, but simply getting vaccinated and following the basic rules of hygiene you learned as a kid could make all the difference.
