Medriva’s WHO-PQS Auto-disable syringes for fixed dose immunization are safe and easy to use. The evaluated technology activates the auto-disabling function the moment the dosage has been taken up. The syringe is rendered unusable immediately after injection of the vaccine. No manual activation is required.

Medriva’s auto-disable syringes are already used for various vaccination campaigns including on the current SARS-CoV-2 vaccines.
