The Prevnar vaccine, developed at the University of Rochester, has shown remarkable real-world effectiveness in reducing invasive pneumococcal infections by 69% among children under two years old. This translates to approximately 20,000 fewer cases of infection each year in the United States.
The study found that vaccinated elderly patients were 48% less likely to die during the 1998-99 season and 50% less likely to die during the 1999-2000 season. Additionally, vaccinated patients were less likely to develop pneumonia, cardiac disease, and stroke, confirming previous VA research on flu shots' life-saving benefits.
The St. Jude team successfully developed a custom-made vaccine against the H5N1 flu virus in just four weeks, thanks to a modified technique called reverse genetics. The vaccine was created by mixing genes from H5N1 with those from a common flu virus, making it safe for human use.
Researchers found that mindfulness meditation increased activity in the left side of the frontal region, associated with lower anxiety and a more positive emotional state. The meditation group also showed a significantly larger increase in immune function compared to the control group.
The Jordan Report 20th Anniversary outlines significant advancements in vaccine research for diseases like HIV/AIDS, tuberculosis, malaria, and bioterrorism threats. The report emphasizes the importance of vaccines in preventing illness and death from infectious diseases.
A Stanford researcher found that vaccinating the entire population and using antiviral medications on those who get sick benefits society. The study found vaccination strategies were optimal in 95% of runs, with treatment of flu patients also benefiting 85% of the time.
Dr. Poland urges healthcare providers to improve influenza vaccination rates among the elderly, citing decades-long progress as 'unacceptably slow.' He proposes several strategies to achieve universal vaccination, including standing-order programs and reimbursement by Medicare.
The National Institute of Allergy and Infectious Diseases (NIAID) has expanded its vaccine testing network, which has been a national resource for vaccine development since 1962. The new network will test vaccines against potential agents of bioterrorism and assess emerging hypotheses about vaccine-related adverse side effects.
Researchers at Princeton University developed a mathematical method to predict the coming year's flu strain based on previous years' genetic sequences. The approach identified clusters of genetically similar viruses that tend to dominate in each season, with an accuracy rate comparable to existing methods.
A study by René Verreault and colleagues found that past vaccine exposure was associated with a reduced risk of developing Alzheimer's disease. The researchers used multivariate logistic regressions to compare vaccinated and non-vaccinated subjects, adjusting for age, sex, and education.
A new study is testing a diluted form of the traditional smallpox vaccine, aiming to increase available doses. Participants will receive either the full or reduced dose and be monitored for signs of successful vaccination.
Residents from rural areas are less likely to receive preventive health services compared to urban residents, largely due to limited access to healthcare facilities, specialists, and insurance. Cultural factors such as traditional values and reluctance to seek medical care may also contribute to this disparity.
A randomized trial shows that computer reminders can significantly boost vaccination rates for hospitalized patients, particularly those over 65. The system identified eligible candidates and prompted physicians to order vaccinations, resulting in a 51% increase in influenza vaccinations and a 36% increase in pneumonia vaccinations.
A Canadian Medical Association Journal article explores the pros and cons of Ontario's no-cost flu vaccine program, which aims to ease pressure on emergency services. Experts argue that while the program may be a step forward in influenza control, its effectiveness and cost-effectiveness are uncertain.
A study found that inactivated flu vaccine (TIV) was associated with lower health care visits and hospitalizations for pneumonia and influenza compared to the intranasal live attenuated influenza vaccine (LAIV) among US military personnel. TIV may be more effective than LAIV in preventing morbidity in highly immunized adult populations.
A study found that concerns about unknown ingredients, inconvenience, and previous side effects are major barriers to flu immunization. Addressing these concerns through outreach efforts and physician-patient interactions can increase vaccination rates in low-income populations.
A recent study from Ohio State University found that stress levels can weaken the immune system's response to pneumonia vaccinations. After six months, vaccinated individuals who were highly stressed showed a weaker immune response compared to those with lower stress levels.
A University of Michigan professor suggests that flu vaccines should be administered when available to prevent lost work days and reduce physician visits, even if not cost-effective for working adults. The vaccine may have a greater impact on the elderly, who are more prone to complications.
A DNA-based flu vaccine has shown promising results in a mouse study, generating high levels of neutralizing antibodies and providing protection at a lower dose. The vaccine combines C3d with HA glycoprotein, priming the immune system against influenza.
The nasal spray flu vaccine protected young children against the A/Sydney flu strain with an 86% efficacy rate, reducing disease severity and middle-ear infections. The two-year study showed overall protection of 92% and significant cross-protection against other strains.
A new study found that flu in children results in substantial use of outpatient medical resources, including 10 physician visits and over half resulting in antibiotic prescriptions. The study suggests that recommending an annual flu vaccine for all children could be a cost-effective national policy.
A new study by University of Michigan professor Dr. Arnold S. Monto found that zanamivir, an antiviral drug, is 67% effective in preventing laboratory-confirmed clinical influenza infection. The drug was also shown to be 84% effective in preventing laboratory-confirmed illnesses with fever.
A University of Iowa study found that nearly 70% of older Iowans received the flu vaccine, but only about half got the pneumococcal vaccine. The researchers identified factors such as age, marital status, and access to healthcare as associated with vaccination rates.
A study conducted in India found that pneumococcal serotypes 1, 6, 19, and others were commonly prevalent, with type-1 found in 25% of cases. The researchers also discovered high rates of antibiotic resistance among S. pneumoniae, particularly in urban areas.
A new study found that women under 65 with certain chronic medical conditions experience substantial morbidity and mortality from acute cardiopulmonary events during influenza season. The study suggests that stronger efforts to reach younger high-risk patients are needed to improve influenza vaccination levels.
Healthcare professionals who received the flu vaccine lost significantly fewer days of work due to illness compared to those who did not receive the vaccine. The vaccine also reduced the rate of influenza type A and B infections among vaccinated individuals.
A new nasal spray vaccine, FluMist(TM), has shown promising results in preventing the flu and flu-related ear infections in children. The vaccine provided 93% protection against the flu and 98% protection against otitis media, a common complication of the flu.
A new intranasal influenza vaccine has been shown to provide 93% protection against the flu in healthy young children. The vaccine was well-tolerated and safe for administration in a nasal spray format, offering an attractive alternative to traditional injection-based vaccines.
A new nasal flu vaccine has delivered good antibody responses and proven safe in children, offering a potential solution to stop the spread of the disease. The vaccine's effectiveness is now being analyzed in a larger study, which may lead to FDA approval starting in 1999.
