(Multiple trade names—Multiple manufacturers)
Jet injector devices not recommended

Jet injector devices should not be used to administer influenza vaccines, according to a FDA communication. Approved influenza vaccines are not labeled to be used with a jet injector. The only vaccine currently approved for administration by jet injector is the measles, mumps, and rubella (MMR) vaccine.

According to the agency, influenza vaccines are only approved for administration by needle injection or nasal mist sprayer. The injectable influenza vaccines should be administered via the intramuscular, subcutaneous, or intradermal routes in accordance with their labeling using a needle and syringe unless otherwise specified.

The influenza vaccines have not been evaluated for delivery by jet injection and this method of administration represents a different method of delivery that has the potential to change the characteristics of an approved vaccine. The agency recommends that all approved vaccines, including influenza, be administered in accordance with their labeling and that health care professionals carefully review the Dosage and Administration section of approved vaccine labeling and the product labeling on injector devices prior to any vaccine administration.
