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.

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.

The study suggests that improving communication between doctors and patients about the benefits of flu vaccination is crucial.
A study found that only 54% of nursing home employees received an influenza vaccination, despite the high susceptibility of elderly residents to the virus. Inaccurate beliefs about vaccination and influenza among staff also contributed to low vaccination rates.
Only about half of teenage girls receive the HPV vaccine at the recommended age of 11-12, leaving them unprotected against cervical cancer and genital warts. Researchers found that rates of HPV infection increase significantly among young people between 14-24, emphasizing the importance of early vaccination.

The study followed 260,493 girls and found no significant increase in pregnancies or sexually transmitted infections among those who received the vaccine.
Researchers highlight gaps in vaccination due to skepticism about childhood vaccines and international travel bringing measles into the country. Experts call for accessible vaccination and research on addressing public concerns about vaccine safety.
Researchers estimate that vaccinating babies against meningitis B disease could reduce cases by 26% in the first five years. The maximum reduction would be achieved by combining infant vaccination with an adolescent vaccination at 13-years-old.
A survey of 1,000 incoming Grand Valley State University students found that moral or religious beliefs were the primary obstacle to receiving the Human Papillomavirus (HPV) vaccine. The study, led by graduate physician assistant researchers, aimed to understand the influence of media on HPV and vaccine compliance.
Pediarix is the most cost-effective combination vaccine, but Pentacel's sales are higher due to overlooked factors. Health care providers often overlook extra immunizations required for certain vaccines.
Researchers found that small financial incentives increased completion of hepatitis B vaccination among injecting drug users, with 45-49% completing the course compared to 9%. The study suggests offering financial incentives can be achieved in routine clinical practice and improve public health outcomes.

The research estimated that three doses of the vaccine provided 46% protection against high-grade cervical abnormalities and 34% protection against other cervical abnormalities.
Research from the University of Kent found that stronger belief in anti-vaccine conspiracy theories is associated with lower intention to vaccinate. This study suggests that anti-vaccine conspiracy theories may present a barrier to vaccine uptake, posing significant consequences for children's health.
A study by Columbia University's Mailman School of Public Health found that sending text messages to low-income obstetric patients resulted in a significant increase in influenza vaccination rates. Women who received the messages were 30% more likely to be vaccinated, with a subgroup showing a 61.9% vaccination rate.
Research suggests that northern China conduct annual vaccinations starting in October, while southernmost provinces vaccinate in February. The study aims to optimize the timing of future vaccination programs and provides a clear picture of influenza seasonally across China.
The study found that HPV vaccine initiation and completion rates were consistently lowest in the South, with 14% and 6% of women completing the series, respectively. The researchers believe regional disparities may be due to factors such as income, education, and insurance coverage.
A recent study found no significant increase in serious diseases among HPV-vaccinated girls compared to unvaccinated peers, despite monitoring over 900,000 participants. The researchers also noted that mild adverse reactions such as fever and swelling are common but not considered a concern.
A study published at IDWeek 2013 found that low-income girls from Spanish-speaking families were less likely to receive the HPV vaccine due to a lack of encouragement from healthcare providers, while English-speaking parents cited concerns over vaccine safety and perceived risk. The findings highlight the importance of culturally sensi...
Researchers at Indiana University have developed a novel vaccine that effectively reduces the shedding of genital herpes virus, potentially providing a new treatment option for those affected. The vaccine, GEN-003, is one of the first to target viral shedding, which is often how the disease is spread.
A 13-year Kaiser Permanente study found no association between vaccination and increased risk of Guillain-Barré syndrome. Researchers controlled for seasonality and analyzed 415 cases, finding only 25 patients had received a vaccine in the six weeks prior to illness onset.
A new PLOS Collection evaluates the effectiveness of maternal, newborn, and child health interventions in low- and middle-income countries. The study reveals that some coverage indicators can be measured accurately, while others require further investigation to ensure valid results.
A study published in Canadian Medical Association Journal found that physicians who followed recommended screening and vaccination practices had more likely patients to also follow these practices. The research involved 1488 physicians and their adult patients in Israel's largest health maintenance organization, Clalit Health Services.
The efficacy of malaria vaccine candidate RTS,S wanes over four years, from 43.6% protection in the first year to zero by the fourth year. The study found that relative vaccine efficacy declines with increasing exposure to malaria, and a booster dose may be needed to sustain efficacy.
