Google has teamed up with the government.
It launched its own flu shot finder.
You can type in your zip code to find clinics with available seasonal and H1N1 vaccine.
I tried it out this morning. It seems to be working well. However it does not have the information about school districts vaccinating. Also, many clinics say they are temporarily out of the H1N1 vaccine. So if you use this, I suggest calling clinics first to make sure the information is up to date.
