Jet injection devices not for flu vaccine, FDA advises

Influenza vaccine has not been approved for administration with jet injection devices and should only be given via needle injection or nasal mist sprayer, the FDA emphasized in a recent communication to health care providers.

“At this time, there are no vaccines for the prevention of influenza disease that are approved for administration by jet injector,” the organization wrote.

Different methods of delivery have the potential to change the characteristics of approved influenza vaccines, according to FDA, and safety and effectiveness data for new different forms of administration must first be submitted to the agency's Center for Biologics Evaluation and Research before approval.

No such data is available for any formulation of influenza vaccine, the FDA said. Currently, the measles, mumps and rubella (MMR) vaccine is the only immunization approved for administration using this method.
