    A collaborative team from the University of Texas Medical Branch at Galveston, Saudi Arabia and Canada has developed a potent and safe vaccine that protects against the deadly Middle East respiratory syndrome (MERS). The findings recently were published in The Journal of Infectious Diseases.

    MERS was first identified when someone died from the viral infection in 2012. The virus, which can suddenly cause severe and fatal respiratory symptoms, systemic infection and multi-organ failure, has caused more than 2,250 confirmed infections with a 35 percent mortality rate in 27 countries. MERS can be spread from camel-to-human or person-to-person. Many global cases are linked with the Arabian Peninsula because of its high camel population but it has the potential to spread globally, as seen in a 2015 outbreak in South Korea.

    “In the past, we’ve mainly focused on developing universal influenza vaccines by targeting the viral proteins to specific cells that have a molecule called CD40 on their surfaces” said senior author Chien-Te K Tseng, professor in UTMB’s Centers for Biodefense and Emerging Diseases. “We modified and optimized our earlier vaccine platform to generate new potential MERS vaccines.”

    Tseng said that although other research groups have investigated various MERS vaccine platforms in animal models, serious safety concerns are often associated with vaccines for the family of viruses that MERS belongs to. The current study set out to use a different vaccine platform that was safer yet still effective.
