As Zika Babies Become Toddlers, Some Can’t See, Walk or Talk

Thursday, December 14, 2017 -- A baby born with microcephaly caused by Zika virus in a rehabilitation center in Recife, Brazil, last year. The most severely affected babies have little language or mobility and will likely require a lifetime of care, a new study shows.

[Research Articles] Durability and correlates of vaccine protection against Zika virus in rhesus monkeys

Wednesday, December 13, 2017 -- An effective Zika virus (ZIKV) vaccine will require long-term durable protection. Several ZIKV vaccine candidates have demonstrated protective efficacy in nonhuman primates, but these studies have typically involved ZIKV challenge shortly after vaccination at peak immunity. We show that a single immunization with an adenovirus vector–based vaccine, as well as two immunizations with a purified inactivated virus vaccine, afforded robust protection against ZIKV challenge in rhesus monkeys at 1 year after vaccination. In contrast, two immunizations with an optimized DNA vaccine, which provided complete protection at peak immunity, resulted in reduced protective efficacy at 1 year that was associated with declining neutralizing antibody titers to subprotective levels. These data define a microneutralization log titer of 2.0 to 2.1 as

Texas Biomed scientists develop new animal model that mimics key features of Zika infection

Tuesday, December 12, 2017 -- An alternative animal model that mimics key features of the Zika virus infection, including its lingering presence in bodily fluids, has been developed at Texas Biomedical Research Institute in San Antonio.

Study bolsters Zika-microcephaly link, rules out others

Wednesday, December 13, 2017 -- Jim Wappes | Editorial Director | CIDRAP NewsDec 13, 2017No link was found between microcephaly and a key insecticide—or vaccines.

[Articles] Association between microcephaly, Zika virus infection, and other risk factors in Brazil: final report of a case-control study

Monday, December 11, 2017 -- The association between microcephaly and congenital Zika virus infection was confirmed. We provide evidence of the absence of an effect of other potential factors, such as exposure to pyriproxyfen or vaccines (tetanus, diphtheria, and acellular pertussis, measles and rubella, or measles, mumps, and rubella) during pregnancy, confirming the findings of an ecological study of pyriproxyfen in Pernambuco and previous studies on the safety of Tdap vaccine administration during pregnancy.
