Vaccine scientists say their "Holy Grail" is to stimulate immunity that lasts for a lifetime. Live viral vaccines such as the smallpox or yellow fever vaccines provide immune protection that lasts several decades, but despite their success, scientists have remained in the dark as to how they induce such long lasting immunity. Scientists at the Emory Vaccine Center have designed tiny nanoparticles that resemble viruses in size and immunological composition and that induce lifelong immunity in...

(Ivanhoe Newswire) -- Breastfeeding moms may want to postpone their next trip overseas or avoid getting the yellow fever vaccine. A new report found that lactating mothers could pass on a strain of yellow fever to their babies, through breast milk. Yellow fever is a viral infection transmitted by mosquitoes. It typically occurs in tropical regions of Africa and in parts of South America. The yellow fever vaccine is a live-virus vaccine that has been used since the 1940s. A new report showed a...

A five-week old infant most likely contracted a vaccine strain of yellow fever virus through breastfeeding, according to a case report published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100619.pdf "Until recently, avoidance of vaccination of breastfeeding women with yellow fever vaccine had been based on theoretical grounds only," writes Dr. Susan Kuhn, with coauthors. "We report the probable transmission of vaccine strain of yellow...

In the first study of its kind, researchers at the Yerkes National Primate Research Center and Emory Vaccine Center, Emory University, have developed a multidisciplinary approach involving immunology, genomics and bioinformatics to predict the immunity of a vaccine without exposing individuals to infection. This approach addresses a long-standing challenge in the development of vaccines--that of only being able to determine immunity or effectiveness long after vaccination and, often, only...

In one of the first molecular studies of the human antibody response to yellow fever, Howard Hughes Medical Institute (HHMI) researchers and their colleagues have found the crucial bit of virus that people's immune systems need to spot and quash this often-fatal re-emerging disease. The findings may help scientists improve the existing vaccine, which has rare but severe side effects, said Jan ter Meulen, an HHMI international research scholar and associate professor of virology at Leiden...
