FDA considering dividing Jynneos doses into fifths to increase vaccine supply - The Hill

“We’re considering an approach for the current doses of Jynneos that would allow health care providers to use an existing one dose vial of the vaccine to administer a total of up to five separate doses,” Califf said.

“This approach which we’re referring to as dose-sparing, would change the method of administration for Jynneos which currently administered subcutaneously.”.

According to Califf, this proposed change would involve injecting the reduced Jynneos doses in between layers of skin, creating a “pocket” for the vaccine.
