NewsImmune response to dengue can predict risk of severe reinfections
Researchers have found that natural killer T (NKT) cells influence whether the immune response generates protective antibodies that neutralise dengue virus or harmful ones that could exacerbate the disease in future infections.

NewsResearchers home in on vaccine target in an ancient scourge
Researchers and doctors have collected one of the most extensive genomic surveys of the syphilis bacterium to date and correlated the genetic data with clinical information about the patients who provided the samples.
-
NewsTwo-dose schedule could make HIV vaccines more effective
Researchers have found that the first dose primes the immune system, helping it to generate a strong response to the second dose, a week later.
