Researchers have come up with a vaccine that is effective against the four strains of the deadly disease that has proven effective on trials using monkeys. Annually, there are a reported million cases of infection that comes mostly from the tropics and people who have been to such areas. Two of the four types are deadly, hemorrhagic fever and dengue shock syndrome the tetravalent vaccine hopes to address. Proteins from all four viral strains were combined along with an adenovirus agent that resulted in the vaccine that promises to be the best yet.
Effectiveness is total and after the necessary trials the study aims to go fast to clinical trials so the millions of people around the world won’t have to fear the possibility of death from the virus and it’s strains. The virus has killed a lot of people, mostly from the two virulent strains that often resulted in death due to non-existent treatment options. Possibility of a vaccine would greatly enhance survival rate and eventually halt the mortality from such a disease that has caused death and grief.
