The first flu shot that works with a tiny needle and less-scary skin prick hits the market this fall. So far it's just for grown-ups.
There are still plenty of other varieties to go around, including the needle-free, squirt-in-the-nose option. There's also a special high dose shot for seniors.
At least 166 million doses of flu vaccine are expected to be produced this year. This year the vaccine is a duplicate because the three strains that made people sick last year are still going around.
A yearly vaccination now is recommended for virtually everyone, except babies younger than 6 months and people with severe allergies to the eggs used to make it. Last year, 49 percent of children and 41 percent of adults were vaccinated.
