Therefore, it makes the revelation of a new vaccine developed by the University of Maryland very welcome. The study was published in the Journal Nature Medicine. This vaccine, though in Phase I clinical trial, was found to confer protection in vaccinated individuals for up to a year in more than half of the trial participants......To Read More....
