It's the first full day of autumn and flu season is fast approaching. Health experts say it's not too early to start making plans to get your flu shot.
The Springfield-Greene County Health Department says this year's version of the flu vaccine will protect against three different strains, including the H1N1 virus.
And they encourage you to get vaccinated as soon as you can because it takes time for the antibodies to build up in your system to offer you full protection.
Even if you had a flu shot last year, you'll need another one this year, health experts say.
Retail pharmacies like Walgreens and Walmart are already offering flu shots. Public health departments will also begin offering flu clinics soon.
