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.

Scientists mobilize to counter vaccine misinformation
A group of public health experts and scientists is mobilizing to counter vaccine misinformation from federal agencies, in an effort backed by Walmart heiress Christy Walton that could eventually produce independent product evaluations and clinical guidelines. Why it matters: It's the latest bid to push back against vaccine skepticism the group's founders contend is threatening to compromise federal public health agencies and the information they disseminate. The initiative is led by former FDA commissioner Margaret Hamburg and former National Academy of Medicine president Harvey Fineberg and will operate as part of the University of Minnesota's Center for Infectious Disease Research and Policy (CIDRAP). Driving the news: The newly formed Vaccine Integrity Project aims to start meeting with medical associations, state health officials, insurers, pharmacies and others next month on steps such as establishing a network of subject matter experts to conduct science-based reviews of vaccines. The effort is supported by an unrestricted gift from Alumbra, a foundation established by Walton, the widow of Walmart heir John Walton. "This project acknowledges the unfortunate reality that the system that we've relied on to make vaccine recommendations and to review safety and effectiveness data faces threats," said epidemiologist Michael Osterholm, the director of CIDRAP. "It is prudent to evaluate whether independent activities may be needed to stand in its place and how nongovernmental groups might operate to continue to provide science-based information to the American public." Osterholm told Science the group will seek out guidance about potentially "reviewing government decisions and messaging to provide clear and evidence-based information" and about "the potential need for a new independent body to evaluate vaccine safety and effectiveness." Between the lines: The effort comes as Health and Human Services Secretary Robert F. Kennedy Jr.'s vaccine skepticism is putting him at odds with most scientists and some of the industries he's regulating. Some researchers fear he could appoint like-minded individuals to panels that advise the Food and Drug Administration and Centers for Disease Control and Prevention on vaccine policy. Most American adults report having heard or read some false claims about measles or the measles, mumps, rubella (MMR) vaccine. Meanwhile, Idaho recently passed a first-in-the-nation ban on vaccine mandates in businesses and schools, and several other states considered legislation this year that would have banned mRNA vaccines. The other side: A spokesperson for HHS called the Vaccine Integrity Project "a self-appointed echo chamber masquerading as oversight."
