A new study reports a vaccine for a rare viral brain infection, PML, is being developed.
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.
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.
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.
Researchers say better adherence to vaccines is needed to help prevent measles epidemics occurring in the U.S.
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.
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.
Immunization with the vaccines for pneumococcal conjugate and rotavirus reduces the rates of acute respiratory infections and gastrointestinal infections in small children, thus reducing the need for antibiotic medications. Researchers say if universal childhood vaccination is achieved, an additional 40 million cases of antibiotic-treated illnesses could be prevented each year.
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.
A new vaccine blocks the effects of heroin by preventing the drug from crossing the blood-brain barrier. Researchers believe the vaccine could be helpful in curbing the opioid epidemic.
Researchers are testing a new vaccine and oral medication that could delay or prevent Alzheimer's disease from developing in those with a genetic predisposition.
