Nigeria remains free of wild poliovirus but continues to face outbreaks of circulating vaccine-derived poliovirus type 2 (cVDPV2). According to national surveillance data, 66 cases were reported in 2025. The country remains committed to halting all poliovirus transmission by 2030 by investing in surveillance, routine immunization, and supplementary immunization activities (SIAs). Polio vaccination has been integrated with broader health initiatives through campaigns and community outreach to immunize all eligible children. 5In this context, needle-free intradermal delivery of fractional-dose IPV enables broader vaccine coverage while reducing cost and logistical complexity. 1,4

The large-scale use of Tropis needle-free delivery in Sokoto follows an extensive randomized controlled trial study of Tropis-delivered fIPV in routine immunization conducted with PATH, Jhpiego, the National Primary Health Care Development Agency (NPHCDA), and Sydani. The study, conducted in Nigeria and published in Vaccines4, highlighted that, when compared to the standard of care (full dose delivered with needles), Tropis delivery resulted in:

In addition, Tropis improves vaccine access in austere, resource-limited settings where non-traditional healthcare workers can use a house-to-house strategy to optimize coverage.

“PharmaJet has supported polio vaccination campaigns in Pakistan since 2018, and we are encouraged to see expanded adoption in Afghanistan and now Nigeria,” said Dr. Wouter Latour, CEO, PharmaJet. “Needle-free delivery improves operational efficiency, reduces costs and enhances acceptability. With more than 20 million Tropis ID injections supplied globally, we are making important contributions to the Global Polio Eradication Initiative and accelerating progress towards eradication.”

LJUBLJANA, Slovenia (AP) — Slovenia’s parliament on Friday appointed right-wing populist politician Janez Jansa as the new prime minister, in a shift for the small European Union country that was previously run by a liberal government.

Lawmakers backed Jansa in a 51-36 vote in the 90-member assembly. The new prime minister will need to come back to Parliament within the next 15 days for another vote to confirm his future Cabinet.

Jansa's appointment concludes a postelection stalemate in Slovenia after a parliamentary ballot two months ago ended practically in a tie. Former liberal Prime Minister Robert Golob's Freedom Movement won by a thin margin but he was unable to muster a parliamentary majority.

Jansa and his populist Slovenian Democratic Party signed a coalition agreement this week with several right-wing groups. The new government also has the backing of a nonestablishment Truth party that first emerged as an anti-vaccination movement during the COVID-19 pandemic.

The new term in office will be the fourth for the veteran Slovenian politician. Jansa, 67, is an admirer of U.S. President Donald Trump and was a close ally of former populist Hungarian Prime Minister Viktor Orbán, who was defeated in a landslide election last month.

Jansa in a speech listed the economy, fight against corruption and red tape, and decentralization as key goals of the future government. He has promised to lower taxes for the rich and support private education and healthcare.

Critical of the previous government's alleged “inefficiency," Jansa said the new government will turn Slovenia into “a country of opportunity, prosperity and justice, where each responsible citizen will feel safe and accepted."

Like Orban, Jansa was staunchly anti-immigrant during the huge migration wave to Europe in 2015. Also like Orban, Jansa has faced accusations of clamping down on democratic institutions and press freedoms during a previous term in 2020-2022. This led to protests at the time, and scrutiny from the European Union.

Golob in his speech described Jansa as “the greatest threat to Slovenia’s sovereignty and democracy."

Alleging that Jansa had threatened to arrest him, Golob said Jansa's "idea of democracy is that anyone who dares speak a word against you deserves only the worst.”

Jansa, a supporter of Israel, also has been a stern critic of the Golob government's 2024 recognition of a Palestinian state.

The vote on March 22 was marred by allegations of foreign influence and corruption. The around 2 million people in the Alpine nation are deeply divided between liberals and conservatives.
