Assessing the impact of needle-free delivery on Nigeria’s routine immunization program for intradermal delivery of poliovirus vaccine
GOLDEN, Colo. — October 24, 2023 — PharmaJet® , a company that engineers precision delivery systems that overcome the challenges of vaccines and pharmaceuticals delivery, today announced the implementation of a study in Nigeria to evaluate the impact of intradermal vaccine administration of fractional inactivated poliovirus vaccine (fIPV) using their Tropis® ID Needle-free Injection System (NFIS). The study, in collaboration with the National Primary Health Care Development Agency (NPHCDA), Jhpiego , PATH and the Sydani Group, is assessing coverage rates, and the potential for reduced costs, associated with using Tropis for fIPV delivery, as compared to the current standard of intramuscular delivery of full dose IPV using needle and syringe. Partners are also evaluating the acceptability and feasibility of using needle-free from the healthcare worker and caregiver perspective.
Implementation began in mid-July and will run through January 2024, with children at 22 urban and rural health facilities receiving fIPV with Tropis. Evidence from the study is intended to inform policy regarding intradermal delivery of polio vaccine in routine immunization settings.
As previously reported, the study, entitled Evaluating the impact of needle-free delivery of Inactivated Polio Vaccine on Nigeria’s routine immunization program is funded by a multi-year grant from the United States Agency for International Development (USAID). High vaccine costs of IPV immunization, limited regional supplies of vaccine, vaccine hesitancy, and logistical barriers in remote areas are among the immunization challenges that have left more than 14.3 million children in low-income regions around the world without proper immunization to poliomyelitis.1 The study aims to focus on key metrics that will determine if the implementation of Tropis for routine immunization can address some of these challenges.
Study preparation included the development of standard operating procedures to ensure congruence with the country’s existing medical guidelines. Hands-on training with healthcare workers was completed prior to the launch. Initial feedback from medical personnel following the training was that the system was fast and easy-to-use.
“We are pleased to be collaborating with NPHCDA, Jhpiego, PATH and Sydani Group on this important innovative routine immunization program in Nigeria,” noted Paul LaBarre, Vice President of Global Business Development, PharmaJet. “This builds on our experience in Pakistan where Tropis has been demonstrated to increase coverage rates. Including additional campaigns in Somalia, we have provided more than 10 million syringes for polio immunization programs.2 On this World Polio Day 2023, we restate our commitment to the Global Polio Eradication Initiative.”
