UT AUSTIN A new vaccine delivery method preserves live viruses, bacteria, antibodies, and enzymes without refrigeration, researchers report. The new method, a peelable lightweight film that stabilizes biologics and withstands extreme temperature changes, could make access to vaccines around the world easier. The technology has already demonstrated proof of concept for model Ebola and H1N1...

An anti-Lyme disease vaccine for mice could help prevent human infections
by Gregory B. Hladky The key is finding a way to give a specially developed vaccine to white-footed or deer mice, carriers that are one of the major ways that Lyme disease bacteria get into the ticks that eventually infect humans. Scientists at the Connecticut Agricultural Experiment Station recently finished a three-year study that provided...

Dual-layer nanoparticle vaccine lays foundation for universal flu shot
By Michael Irving It might seem like little more than a seasonal nuisance these days, but the flu is a massive and potentially deadly health problem for the world to deal with. The virus mutates quickly and unpredictably, making it hard to develop effective vaccines. Now, researchers at Georgia State University have combined two antigens to...

Live zoster vaccine safe and effective for people taking TNF inhibitors
AMERICAN COLLEGE OF RHEUMATOLOGY ATLANTA — According to new research findings presented this week at the 2019 ACR/ARP Annual Meeting, the live zoster virus vaccine is safe for people who are currently receiving tumor necrosis factor inhibitor (TNFi) biologic therapies for various indications (Abstract # 824). In healthy individuals, excess TNF in the blood is...

Vaccine reduces likelihood of severe pneumonia
MURDOCH CHILDRENS RESEARCH INSTITUTE A new study has found severe pneumonia decreases by 35 per cent in children who receive a vaccine against a pneumonia-causing bacteria. The research, a collaborative effort between the Murdoch Children’s Research Institute (MCRI) and the University of Melbourne along with colleagues in the Asia-Pacific region, shows pneumonia is the most...

Anti-vaxxers find ways around ‘personal exemption’ bans
by Amy Norton When parents can no longer get “personal-belief” exemptions from childhood vaccinations, they may get around it by asking for religious exemptions for their kids, a new study finds. Researchers found that after Vermont banned personal-belief exemptions, the number of kindergartners with religious exemptions from vaccination suddenly shot up—from 0.5% to nearly 4%....

Vaccine candidate for gonorrhea shows preclinical effectiveness
by University of Massachusetts Medical School A report in the journal mBio, published by the American Society for Microbiology, describes a prototype vaccine candidate for Neisseria gonorrhoeae, the bacterium that causes gonorrhea, a sexually transmitted infection that affects men and women. Untreated, gonorrhea can cause infertility in women. “The global spread of multidrug-resistant strains of...

Novel antibodies could provide a universal flu vaccine
Currently available flu vaccines are based on the rapidly changing viral hemagglutinin (HA) antigen, and are therefore quickly outdated. Thus new vaccines need to be developed each year. Now, a new study published in the journal Science on October 25, 2019, reports on a set of three novel antibodies that bind to another type of...
