We always get ours as early as possible. It really irritates me that I can go to Walgreens and get the flu shot for DH and I as early as August, but my children's pediatrician tells me they won't have them until late October! We have always gotten ours at the end of August or beginning of Sept, and we have never gotten the flu. I am desperately trying to figure out where my kids can get them before all the illnesses start circulating. I just don't understand why doctors get them so much later than pharmacies.
I know the shot only protects against the flu, but they can't get the shot if they're sick, and once October rolls around, they start getting all the stuff from school. Plus, my son started elementary school this year, so...new germs!
