Parents who refuse to vaccinate their children against the flu may be exposed to limited, or inaccurate, information that impedes their decision, researchers report.
A new DNA vaccine tested in mice significantly reduces tau and amyloid beta, two proteins implicated in Alzheimer's disease. The findings, researchers say, may pave the way for clinical trials in humans with the neurodegenerative disease.
Study reports past problems with vaccine research can cause hysteresis, or a negative history that stiffens the resolve of some against vaccinations. The findings shed light on why it is hard to improve vaccine uptake, even when there is overwhelming evidence of the safety and benefits of vaccinations.
Another new study refutes claims of a link between the MMR vaccine and autism. The study reports no link has been found between MMR and an increased autism risk, even in children with other risk factors for ASD. Researchers also reported, in a subgroup of girls, the MMR vaccine reduced the risk of autism by between 16% and 21%. No link was found between other vaccinations, such as Hib and DTaP, and an increased risk of ASD.
Researchers will present a systematic review of scientific evidence for, and against causal associations for 47 proposed adverse events following immunizations at PAS 2019. The review found that, for 12 of the 47 AEFIs in the study, a causal relationship has been established with at least one vaccine. With the exception of deltoid bursitis, where a vaccine is administered incorrectly, causing pain to the arm, the adverse reactions are very rare. For the other 35 AEFis, the evidence does not support a causal relationship between conditions, such as ASD, asthma, diabetes, multiple sclerosis or SIDs, and vaccinations.
Current vaccination policies are not sufficient to eliminate measles or prevent against future epidemics in the developed world, researchers report. Introducing compulsory vaccinations before entering school would allow the US, UK and Ireland to reach stable levels of herd immunity in the next ten years, thus helping to avoid future epidemics of the most lethal vaccine-preventable disease.
From anti-vaccine rhetoric to the over-prescription of antibiotics, researchers suggest we should try to work together to improve public health, rather than socially shun those who ignore scientific evidence.
A large, genome-wide study in children reveals genetic variants associated with differing levels of antibodies produced as a result of three common childhood vaccinations. Researchers identified two genetic loci associated with the persistence of vaccine-induced immunity following early life vaccinations. The results may help clinicians tailor personalized vaccine schedules to maximize the effectiveness of immunizations.
Study reveals how a pregnant woman's vaccine-induced immunities are transferred to her offspring via the placenta. The findings have positive implications for the development of new, more effective maternal vaccines.
A newly developed vaccine for meningitis and other bloodstream infections caused by the meningococcal group B bacteria will allow for the immunization of younger children. The new vaccine also addresses several limitations of the current meningitis vaccine.
Recently, the WHO declared vaccine hesitancy one of the top ten international public health problems. They report the crisis is man-made, unnecessary and dangerous. Researchers are calling on search engines and social media organizations to do more to stem anti-vaccine rhetoric, and stop the spread of disinformation surrounding vaccinations. They also call for governments to better support mandatory immunization programs.
A study of over 200,000 people found no evidence that vaccinations increase the risk of developing multiple sclerosis, or the onset of an initial MS episode.
