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.
Researchers have engineered a vaccine using virus-like particles that target Tau tangles in mouse models of Alzheimer's disease. Following the administration of the vaccine, the mice developed antibodies that cleared tau proteins, with the response lasting for a month. The mice also showed improvements in memory based tests and had less brain shrinkage than their peers who did not receive the vaccine. This suggests the vaccine prevented apoptosis. Researchers hope to move the vaccine to human clinical trials in the future.
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.
Researchers report one method to help combat anti-vaccine information and reduce vaccine hesitancy is to introduce those with negative views about immunizations to someone who has suffered a vaccine-preventable disease. The study reports 70% of students who were exposed to someone with a vaccine-preventable disease moved from vaccine hesitancy to pro-vaccine. Overall, 75% of those who were anti-vaccine increased their vaccine attitude scores, with 50% moving to a pro-vaccine stance.
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.
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.
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.
Researchers have successfully neutralized a genetic risk factor found in up to 80% of Alzheimer's patients. The ability to neutralize ApoE4 could help in the development of a vaccine, as well as other therapeutics, for late onset Alzheimer's.
Researchers report skepticism that the flu vaccine can cause autism, is ineffective and can result in contracting the virus prevents some parents from vaccinating their children.
Researchers report Russian trolls and bots are significantly involved in promoting discord and spreading false information about vaccines on Twitter. The study reports these accounts shared anti-vaccination messages 75% more than average Twitter users.
According to researchers, over 50% of people in some European countries still believe the myth that vaccines cause autism, despite the claim being widely discredited. A new paper looks at why so many people may still believe the vaccine-autism link is real.
