Research led by the University of Pittsburgh School of Medicine found that state laws mandating influenza immunization for health care workers increased their vaccination rates from 22.5% to 50.9% between 2000 and 2011. The study suggests that stronger laws, including mandates and education, lead to higher vaccination rates.
Researchers at Arizona State University have developed a simpler method to produce antibodies against a range of infectious agents using DNA-based genetic immunization. The technique successfully expressed membrane proteins in mice and induced the animals to produce critical antibodies to bacterial and viral targets.
Global experts celebrate a major public health achievement with the introduction of MenAfriVac®, a vaccine designed for Africa that has nearly eliminated serogroup A meningococcal disease.

A recent study by the CDC and University of Georgia found that 75% of first-time expectant mothers planned to follow the recommended childhood immunization schedule. Most undecided mothers had low levels of confidence in vaccines, suggesting targeted outreach may be needed.
A patient with an immune deficiency has shed large amounts of live polio virus in their stool for over 20 years, posing a risk to global polio eradication. The highly mutated strain has acquired mutations that reverse the attenuating features of the vaccine strain, making it more difficult to neutralize.
A new study from the University of Michigan Health System found that electronic prompts and reminders resulted in significant increases in Tdap vaccine uptake among patients aged 11-64. The system improved vaccine rates by 76% for adults and 85% for adolescents, compared to 59% in similar-aged groups without automated prompts.

Underimmunization ranged from 18% to 23% within clusters, compared to 11% outside clusters, highlighting areas with high vaccine refusal rates.
Vaccines targeting HIV can backfire and lead to increased infection rates if they activate too many viral target cells. A recent primate model study found that higher levels of activated CD4+ T cells in mucosal tissues were associated with an increased risk of infection.
Researchers found that wearing a hijab buffers against negative body image among British Muslim women, reducing reliance on media beauty standards and emphasis on appearance. The study suggests the hijab helps some women reject prescriptive beauty ideals.
Researchers have successfully mutated the powerful anti-HIV bNAb called VRC01 to make it last longer in blood and collect in rectal mucosal tissue, potentially blocking HIV transmission. A low-dose infusion of mutated VRC01 also protected monkeys against SHIV infection more effectively than unmutated VRC01.
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.
A study found a significant reduction in HPV types 16 and 18 infections among young women in England after the introduction of the HPV vaccination program. The prevalence dropped from 1 in 5 to 1 in 15 among those aged 16-18, with the lowest rates among vaccinated individuals.
A study found that changing hospital orders increased pertussis immunization rates by 69% among new mothers, providing protection for themselves and their newborns. Implementing a standing order led to the largest increase in vaccinations, raising the rate from zero to 69%.

Most bills with administrative requirements restricted exemptions, but none were passed. The study highlights ongoing challenges in maintaining high immunization coverage.
The American College of Physicians and the Centers for Disease Control and Prevention have released an updated adult immunization schedule for 2014. Key changes include the removal of health care worker vaccination as an indication and updated recommendations for certain adults at increased risk for Haemophilus influenza type b (Hib) i...
Scientists have identified a potential treatment mechanism for the EV71 virus, which causes severe brain swelling and paralysis in children. The discovery was made by creating antibodies that can neutralize the virus by inducing genome release, rendering it non-infectious.
A Kaiser Permanente study found that administering the first measles-containing vaccine between 12-15 months old is associated with a lower risk of fever and seizures compared to receiving it at 16-23 months. The study analyzed data from over 840,000 children who received a measles-containing vaccine between 2001 and 2011.
The articles highlight the need for a shift away from leader-centric approaches and towards building trust with communities, prioritizing routine health services, and supporting frontline female health workers. This includes increasing investment and time to achieve stronger health systems and universal immunization in these countries.
A parental survey to measure vaccine hesitancy was linked to children's underimmunization rates. Parents with higher survey scores were more likely to have underimmunized children, highlighting the potential for such surveys as a predictive tool.
The nationwide HBV immunization program, launched in 1984, successfully lowered chronic HBV carrier prevalence, HCC incidence, and mortality of infant fulminant hepatitis in vaccinated birth cohorts. Long-term high-coverage immunization was associated with increased herd immunity and lower IFH mortality rates.
A study by Columbia Nursing researchers found that automated reporting of immunization data through EHRs increased knowledge about individuals and communities, allowing medical and public health officials to make informed decisions. This led to reduced lag times, improved documentation, and enhanced efficiency in vaccine tracking.
The Sabin Vaccine Institute has launched the International Association of Immunization Managers (IAIM) to help drive national, regional, and international immunization goals. IAIM aims to equip immunization managers with tools and a professional network to advance their programs.

A new global surveillance tool detects and monitors public concerns about vaccines, allowing for swift responses to prevent low vaccine uptake and disease outbreaks. The tool analyzes reports from 144 countries, identifying key themes and prioritizing action to promote immunisation.
A new study published in Pediatrics found that flu vaccines are safe for children with inflammatory bowel disease (IBD), without increasing adverse events. The research suggests that receiving the influenza vaccine may even protect against IBD flare-ups and doctor visits.
African experts argue that immunization systems are failing due to issues with vaccine supply, financing, and sustainability. The authors call for strengthened programs to address regional and country-specific problems and develop precise strategies to overcome challenges.
A recent study by Mayo Clinic found that over 2 in 5 parents are hesitant to vaccinate their teenage daughters against human papillomavirus (HPV) due to potential side effects. The vaccine is recommended for teens to prevent cervical cancer and genital cancers, with the majority of experts agreeing on its necessity.
A Kaiser Permanente study found that nearly half of children under 2 years old did not receive all recommended vaccinations. Children who missed scheduled vaccines were more likely to be admitted to hospitals and have fewer doctor visits than those vaccinated on time.
Researchers suggest that vaccinating around 46% of Haitians could arrest the spread of cholera. Using mathematical models to target immunization campaigns can help control recurrent outbreaks and slow transmission rates.

Researchers report progress in Pakistan's efforts to eradicate polio, with the potential elimination of one type of wild poliovirus. However, vaccine refusals remain a major challenge, driven by false rumors and misinformation. In Nigeria, a surge in cases threatens to re-infect countries that have already been cleared of polio.
Researchers found that intravaginal immunization significantly increased immune cells in the vaginal mucosa, enhancing local immune response. This site-specific vaccination technique may be useful in developing effective STD vaccines.
