Insufficient vaccination coverage, particularly in insecure regions, is preventing the elimination of polio in Pakistan and Afghanistan. A new study suggests that introducing bivalent oral poliovirus vaccines could eliminate polio if sufficient numbers of children are reached by vaccination programs.
The GAVI Alliance has pledged an additional $162 million to control and prevent measles outbreaks in six high-risk countries. The funding will strengthen routine immunisation systems and follows a decision last November to provide over $600 million to tackle rubella through a combined measles-rubella vaccine.
The introduction of rotavirus vaccines in developing countries is projected to save more than 2.4 million lives by 2030, with significant reductions in hospitalizations and clinical visits. Rotavirus vaccines are highly cost-effective, reducing child deaths by up to 95% in GAVI-eligible countries.
The CDC's Advisory Committee on Immunization Practices recommends routine HPV vaccination for males aged 11-12 years, catch-up vaccination for males aged 13-21. For adults with diabetes, Hepatitis B vaccinations are now recommended for those under 60 and over 60 based on specific conditions.
Scientists have developed a new approach to treating autoimmune diseases by creating artificial antibodies that target the MMP9 enzyme. These 'metallobodies' mimic natural inhibitors and selectively block two members of the MMP family, preventing symptoms in mice with inflammatory conditions.
A recent study found that less than 47% of adults are properly immunized for tetanus and 39% of those over 65 receive the pneumococcal vaccine. Dr. Vivien Brown advocates for moving immunization to the top of health checklists, with both doctors and patients taking responsibility for tracking vaccination records.

The Expanded Programme on Immunisation has saved millions of lives with vaccine support from WHO and UNICEF. However, diseases like pneumonia and diarrhea still account for a quarter of child deaths in low-income countries. Middle-income countries may struggle to access new vaccines due to high costs.
Developing vaccines against diseases with extensive antigenic variability, such as HIV and malaria, poses significant technical challenges. Tailored vaccination programmes based on individual genetic predispositions could increase safety and efficacy.

Experts emphasize the need for $3.7 billion funding to save 4 million lives through immunization programs.
A clinical trial of the malaria vaccine RTS,S has begun in Africa to assess its effectiveness when administered to newborn babies as part of national immunisation programmes. The study aims to improve the vaccine's performance by examining its impact at different stages between birth and nine months of age.
A new immunological technique has shown that artificially induced malaria immunity can last for at least 2.5 years, significantly longer than naturally acquired immunity. The study found that immune volunteers who were re-infected with the same strain of malaria had a quicker and more effective response to infection.
Children with inborn errors of metabolism received vaccines on the same schedule as healthy infants without significant increases in ER visits or hospitalizations. However, smaller subsets of children may be at increased risk for adverse events during the immediate post-vaccination period.
Researchers found that vaccinating through salivary glands can provide protection against various diseases, including influenza and cholera. The technique involves administering vaccines directly into the salivary glands, which then trigger an immune response both locally and systemically.
A new study by the RAND Corporation found that Hispanic seniors are less likely to be immunized against flu and pneumonia compared to similar White seniors. Researchers discovered that Hispanic seniors who prefer speaking Spanish and live in linguistically isolated communities have the lowest immunization rates.
A new study suggests preterm infants are at risk of invasive pneumococcal disease despite receiving the pneumococcal conjugate vaccine. Early effective immunization is crucial, as they have lower levels of maternally derived antibody than full-term infants.

A study found that vaccine records of internationally adopted children may not guarantee immunity against diseases such as polio, measles, and hepatitis B. The predictive value of immunization records is limited and associated with birth country, due to reasons like falsification, inaccurate entries, and lack of vaccine potency.
The Goldberg Center for Community Pediatric Health at Children's National Medical Center has been recognized as a national leader in improving immunization compliance rates and preventive care visits.

A new delivery method of flu vaccine using microneedle skin patches has shown comparable effectiveness to conventional intramuscular injections. The patch-based approach eliminates pain, increases convenience and could lead to improved seasonal vaccination coverage.
Global epidemiological studies suggest one-third of chronic hepatitis B infections are acquired during infancy and early childhood. Universal infant immunization is offered in most countries (98%) and has reduced incidence rates in provinces that adopted the program.
The study found that global child immunization coverage is significantly lower than reported by individual nations or WHO/UNICEF estimates. The researchers estimated the coverage of three doses of diphtheria, tetanus, and whooping cough vaccine (DPT3) based on surveys using all available data from 193 countries between 1986-2006.
A randomized clinical trial found that half-dose influenza vaccine produced similar antibody responses to full-dose vaccines in healthy adults. Women had a greater response to both doses, suggesting guidelines should consider sex as well as age. This study supports the validity of dose reduction strategies during vaccine shortages.
Two studies published in PLOS Medicine show that increasing flu vaccination rates can decrease the burden of influenza. A universal immunization program in Ontario led to reductions in flu-related deaths, hospitalizations, and emergency department visits compared to other provinces.
A recently introduced polio vaccine is four times more effective at protecting children than previous vaccines, offering a potential path to eliminating type 1 polio in Nigeria. However, many more children need to be immunised against polio if the virus is to be eliminated.

Most children with known or suspected vaccine allergies can be safely vaccinated with proper monitoring and precautions, according to the study.
A study found that immunization with Aβ42 reduced brain amyloid-β plaque formation and improved cognitive function in mice, but failed to prevent dementia progression in humans. Despite clearing associated brain plaques, immunized patients did not show improved survival or increased time to severe dementia.
The US healthcare system struggles to vaccinate adolescents, despite three new vaccines available to prevent five serious diseases. The authors identify unique issues, including consent, financing, and surveillance, that require national attention to improve adolescent immunization.
Key findings include significant variability in coverage gaps across countries, with poorest quintiles facing substantial gaps, and only a few countries showing declines greater than 2% per year. The authors emphasize the need for accelerated progress to achieve coverage levels needed for MDG4 and MDG5.
