Publication in Vaccine Highlights Fewer Adverse Events with PharmaJet Needle-free Intradermal Delivery compared to Needle and Syringe
GOLDEN, Colo.--(BUSINESS WIRE)-- PharmaJet ®, a company that strives to improve the performance and outcomes of injectables with its needle-free injection technology, today announced the publication of a study demonstrating the benefits of the PharmaJet Tropis needle-free system compared with N/S for ID administration of fractional dose poliovirus vaccine (fIPV). The study entitled Tropis needle-free injector for fractional-dose IPV administration: A pilot study for integration into routine immunization services in Cuba is published in Vaccine. 1 In Cuba, the routine immunization (RI) schedule for polio consists of two doses of fIPV administered at 4 and 8 months of age administered intradermally with N/S. However, ID administration with N/S is relatively uncomfortable, complex and requires specific training. Improper technique can result in reduced immunogenicity. 2 Tropis offers an easy to use, reliable technique that has been shown to improve coverage in Pakistan, 3 Somalia 4 and Nigeria, 5 where it has been used to vaccinate nearly 12 million children. Tropis is the first and only needle-free ID delivery technology to achieve World Health Organization (WHO) prequalification. The study measured acceptability, safety, and immunogenicity of Tropis compared to N/S administration with a total of 6,704 children vaccinated. Surveys were administered to parents/guardians (n=5260) and nurses (n=66) to evaluate satisfaction. Additionally, blood samples from vaccinated children were analyzed for neutralizing poliovirus antibody levels. The results indicated significantly fewer adverse events with Tropis (6%) than N/S (13%) (p =0.028), and Tropis was preferred over N/S by large margins by both parents (98%) and nurses (98.5%). Survey respondents cited ease of vaccination, diminished crying, and increased comfort as the benefits of Tropis. Of note, seroprevalence did not differ significantly between Tropis and N/S. This research collaboration between the Instituto Pedro Kourí (IPK) and the WHO was conducted to gain valuable insights that can be applied to curb the global circulating vaccine-derived poliovirus. Cuba has proven a useful resource and partner for polio eradication, acting as an incubator for testing new ideas and approaches. The WHO–Cuban collaboration, lasting for over 20 years, has been vital for the Global Polio Eradication Initiative (GPEI), making it possible to design innovative strategies, especially for the polio eradication endgame and for immunization policy development worldwide. 6 'These results highlight that Tropis results in fewer AEs than Mantoux technique and is more acceptable. This should be very encouraging to vaccine programs aiming to take advantage of ID delivery,' said Paul LaBarre, Vice President of Global Business Development, PharmaJet. 'The strong performance of Tropis ID delivery is consistent with results recently seen in WHO-sponsored polio campaigns in Pakistan, Nigeria, and Somalia where Tropis has been used to administer polio vaccinations to nearly 12 million children.'

About Cuba's role in the collaboration with the WHO and GPEI 2 Cuba's part in the continuing collaboration with the World Health Organization (WHO) has focused on issues relevant to policymaking for the ongoing global polio eradication effort. It has concentrated particularly on looking for answers to scientific questions that could not be answered elsewhere, taking into account Cuba's unique OPV vaccination program, conducted only twice annually, usually in February and April. Specifically, research has addressed several aspects of OPV and inactivated poliovirus vaccine (IPV), such as immunogenicity, adverse reactions and complications, persistence of Sabin virus in populations, the immunogenicity schedule and its affordability, number of doses needed, evaluation of new vaccines and devices, and booster response.

Catch-up polio drive in high risk areas from Saturday
The Sindh Government, in collaboration with its partners, has launched a targeted polio vaccination campaign. The first phase, which begins today (Saturday) will focus on 27 high-risk union councils in Karachi. The campaign aims to strengthen children's immunity and curb the transmission of the polio virus. In this first phase, 562,163 children under the age of five will receive the Oral Polio Vaccine (OPV), while 521,953 children aged four months to under five years will receive the Fractional Inactivated Polio Vaccine (fIPV) using painless jet injector technology. As Pakistan's largest and most densely populated city, Karachi remains a critical battleground in the fight against polio. The city's frequent population movement contributes to the persistent presence of the polio virus in environmental samples. Despite repeated vaccination efforts, transmission risks remain high, making targeted campaigns essential to closing immunity gaps and protecting children from lifelong paralysis. The use of painless jet injector technology for fIPV administration ensures a needle-free, stress-free experience for children. The combination of OPV and fIPV further strengthens immunity, offering additional protection in areas where the virus continues to circulate. Recently, in August 2024, a successful f-IPV campaign was conducted in the megalopolis.
