Needle-free inoculation: No doctor necessary: US okays nasal spray flu vaccine for self-use

The US Food and Drug Administration has approved AstraZeneca's FluMist nasal spray for self-administration, making it the first flu vaccine available without a healthcare provider. Starting next fall, Americans aged 18 and over can order the needle-free spray online after a screening, with hopes that the convenience will boost vaccination rates, which have declined in recent years.
