Researchers enrolled over 5,000 participants and found no significant difference between the two vaccine formulations.
A new study suggests that localized vaccination surveillance can help predict and prevent measles outbreaks by analyzing geographic clustering of non-vaccinators. The researchers found that even at high overall vaccination coverage, clustering of non-vaccinators increases the probability and size of an outbreak.

This suggests that vaccination is perceived as a societal obligation, transcending social group affiliations.
A Washington State University study found that words matter in vaccination messages, with normative and injunctive messages increasing interest and vaccine intention. Negatively worded messages can decrease interest, highlighting the importance of using effective promotional messaging to improve vaccine uptake.

Researchers at Trinity College Dublin have discovered that only 17% of badgers disperse from their home territories, with females traveling long distances in search of new habitats. Understanding this behavior is crucial for implementing effective vaccination programs to limit TB transmission.
Researchers examined over 500 vaccine-related ads on Facebook and found that a small group of anti-vaccine ad buyers targeted specific audiences, while pro-vaccination ads were often rejected due to Facebook's policies. The study highlights the need for social media platforms to balance free speech with public health concerns.
Researchers detected oral HPV DNA in 6.2% of teen and young adult female participants, with detection decreasing over time since becoming sexually active. The study suggests that the HPV vaccine is less effective against certain types of oral HPV in vaccinated individuals compared to those who are fully unvaccinated.

The research aims to prevent congenital transmission of CMV by targeting pregnant women.
A study published in PLOS ONE found that individuals' vaccination attitudes are shaped by their proximity to a disease outbreak, particularly for those who distrust government medical experts. On the other hand, people with high levels of trust in government experts are not affected by disease proximity.
A new study published in Papillomavirus Research found that one dose of HPV vaccine lowers the chance of having a pre-cancerous lesion detected at cervical screening in women vaccinated at a young age. The data supports the possibility that one dose may be sufficient for protection, simplifying vaccination and potentially benefiting co...

Researchers discovered a new badger behaviour where some males range widely across multiple territories, gaining access to more female badgers and potentially increasing disease transmission. This finding could help pinpoint areas of high risk for TB transmission, informing effective vaccination strategies.
A recent study in northwest Pakistan found that high insecurity increases access issues for vaccinators and vaccination rates, leading to a higher incidence of polio. Regional conflict has been cited as a barrier to polio eradication, but this study provides strong evidence supporting the claim.
A new study published in BMC Medicine found that the rotavirus vaccine has a disproportionate impact on reducing gastrointestinal disease in the UK's most deprived communities. The vaccine has been shown to decrease hospitalisations and attendances by up to 80% and 32%, respectively, among these populations.
A decade-long study on hundreds of HPV vaccine recipients found the vaccine to be safe and effective in preventing the most virulent strains of the virus. The quadrivalent vaccine was virtually 100% effective in preventing disease in young individuals.
Researchers at Johns Hopkins Bloomberg School of Public Health have discovered a genetic mutation in the FluMist intranasal flu vaccine that has the potential to be altered to enhance its protective effect. The mutation reduces virus production, but reversing it makes the virus more active and induces a stronger immune response.
A Kaiser Permanente study found that pregnant women who used an interactive website monitored by a clinical expert were more likely to vaccinate their children than those without access. The study suggests websites with interactive components can complement face-to-face clinical interactions and combat misinformation.
Researchers argue that acellular vaccines' inability to prevent infections contributes to the disease's resurgence. The study highlights differences in mucosal immunity between whole-cell and acellular pertussis vaccines, which may have led to the increase in cases.
Researchers at George Washington University are testing a candidate recombinant hookworm vaccine in a Phase II clinical trial. The study aims to prove the efficacy of the vaccine against hookworm infection and its potential benefits for millions of people infected worldwide.

A new study suggests that a 'psychological vaccine' can help build tolerance to climate change misinformation, shifting opinions closer to the truth. Researchers found that pre-exposing people to small amounts of misinformation can provide resistance against subsequent exposure.
Researchers found that changing the dosing regimen of the RTS,S/AS01 malaria vaccine improved its efficacy to approximately 87%, compared to 63% with the current standard regimen. The new regimen was shown to delay infection longer and provide better protection against a second malaria-causing parasite exposure.
A national survey found that 21% of parents support HPV vaccination requirements without opt-outs, increasing to 57% when opt-outs are included. Despite the vaccine's effectiveness in preventing cervical cancer, many parents lack knowledge and are hesitant to vaccinate their children.
A new study published in the Canadian Medical Association Journal found that HPV vaccination programs can reduce cervical cell anomalies in young women. The study showed that 3-dose HPV vaccination has demonstrated early benefits against high-grade cervical abnormalities, which are more likely to progress to cervical cancer.
A new study analyzing over 4,000 news articles about the 2014-15 Disneyland measles outbreak found that articles with a clear bottom-line message were shared more than twice as much as those without. The research supports 'fuzzy trace theory,' suggesting that communications focusing on the gist will be more compelling.
A new study found that conflicting expectations between parents and medical providers about scheduling follow-up appointments is the most common reason for patients not completing the HPV vaccine series. Researchers suggest improving education and dialogue between providers and parents to increase vaccination completion rates.
