MEDPAGE TODAY: HPV Shot May Protect Unvaccinated Women Too.
From 2006 to 2023, the adjusted proportion of vaccinated women in the U.S. who were positive for the high-risk HPV-16 and HPV-18 types dropped 98.4%.
The proportion of unvaccinated adolescent girls and young women who were positive for at least one of those HPV types dropped 71.6%.
However, social trends and disruptive policies could lead to a drop in HPV vaccination rates.

Valneva Reports 95% Seroresponse Four Years After Single Shot of Chikungunya Vaccine IXCHIQ®.
Among the 254 healthy adults still followed in the trial, 95% maintained neutralizing antibody titers well above the seroresponse threshold4 four years after the single-dose vaccination. Persistence of antibodies in older adults (age 65+) was comparable to younger adults (18-64 years of age) in terms of geometric mean titers (GMTs) and seroresponse rates (SRRs).

Has Chikungunya Become Endemic in Southern France.
In mid-September 2025, the French Health Ministry reported 97 new locally acquired cases of Chikungunya in thirty-eight active clusters. The largest cluster is located in Antibes and consists of 87 cases. This area of France’s Mediterranean coast is a popular vacation destination, located between Cannes and Nice.

WHO: Cholera upsurge (20021 – present).
Sixty countries reported cases in 2024, an increase from 45 in 2023. The burden of the disease remained concentrated in Africa, the Middle East, and Asia, which collectively accounted for 98% of all reported cases. These trends continue int 2025. This increase in outbreaks and cases is stretching the global capacity to respond. There is a shortage of cholera tools, including vaccines. WHO considers the current global risk from cholera as very high and is responding with urgency to reduce deaths and contain outbreaks in countries around the world.

CEPI backs new research into vaccines against multiple deadly filoviruses.
Supported by up to $18 million in CEPI funding, researchers will design and test innovative vaccine constructs that could offer broad, all-in-one protection against viruses such as Zaire ebolavirus, Marburg virus, Sudan ebolavirus, and even yet-unknown filoviruses that may spill over from animals to humans in the future.
Using advanced artificial intelligence, the team will design immunogens—the components that trigger immune protection—capable of targeting multiple filoviruses. These will be combined with a ferritin-based protein nanoparticle platform to generate a range of vaccine candidates, which will undergo preclinical testing to establish proof of concept. The most promising candidate will be developed to a stage ready for rapid entry into Phase I clinical trials in the event of an emerging outbreak. The ferritin nanoparticle platform is well-suited for low- and middle-income countries, as it does not require complex frozen storage. It has already shown positive safety results in Phase I trials for influenza and COVID-19 vaccines.

Bangladesh launches typhoid vaccination drive to combat drug-resistant threat.
Bangladesh launched a nationwide vaccination campaign on Sunday to protect millions of children from typhoid, a deadly and increasingly drug-resistant disease that poses a growing public health threat. The month-long campaign aims to immunize around 50 million children aged between nine months and 15 years with a single dose of the Typhoid Conjugate Vaccine (TCV). Approved and pre-qualified by the World Health Organization (WHO), the vaccine provides protection for up to five years and is being administered free under the government’s Expanded Programme on Immunization (EPI).

Japan’s health authorities have declared an influenza epidemic, with thousands of people infected with the respiratory virus. The number of infections for this time of year is unusual, say researchers, and could seed outbreaks in countries that are heading into winter in Asia and Europe — although it is unlikely to become a global pandemic.
