Authorities authorize self-administered flu vaccine as a nasal spray

This is “a new option for receiving a safe and effective seasonal flu vaccine that is potentially more convenient, more flexible, and more accessible to individuals and families,” said Peter Marks, a manager at the FDA.

A prescription will still be required to get the vaccine, through an online pharmacy, the FDA detailed. That option will be available starting next fall, AstraZeneca said.

“More accessible”

The vaccine will come with instructions for use, which are being evaluated in a study to make sure they are understood. Minors should not administer it themselves, but their parents or caregivers can.

The approval is “an important step towards making vaccines more accessible,” said Iskra Reic, from AstraZeneca.

The main side effect of vaccines containing live, weakened viruses is fever in children aged 2 to 6 years.

Nearly 200 million doses have been distributed worldwide in the past, according to the company. The vaccine is called Fluenz Tetra in France.

Flu can be dangerous for at-risk populations, especially the elderly or young children. Each season is different in terms of health consequences.
