Yes.
If the swine flu vaccine is not available for them to take (with the pediatrician's advice, of course), then you should discuss having Tamiflu on hand in case the flu hits when doctor/pharmacy is not available. Starting Tamiflu right away is VERY important.
I have tamiflu on hand. In the spring, 20% of their classmates came down with flu. I called and got tamiflu in case my daughter with asthma came down with it. I could only get one prescription of it. My daughter never got sick.
