Children and young people under the age of 25 are among the groups that are recommended to get the vaccine first.
At Dr. Laurie McKillip's pediatric clinic in The Woodlands the phones are ringing non-stop.
"Every single phone call people ask, yes. Probably one every five minutes. They're asking if we will be giving the vaccine and when it will be available."
The CDC recommends all children get the vaccine. And McKillip says children with serious illnesses should definitely receive it. But she leaves it up to parents to decide whether to vaccinate otherwise healthy children.
"A lot of the questions are technology — they're afraid of new technology, they're afraid the vaccine hasn't been tested for safety. If your child has asthma or heart disease or an immunodeficiency I'd probably really encourage you to do it. But for a healthy child, I think that's your choice."
The vaccine for children requires two doses, whether in nasal spray or injection form.
McKillip says she expects to see a lot of kids show up with flu-like symptoms. But she believes the vast majority of those cases will be mild.
