Dengvaxia: Know this Before getting the Shot
Dengvaxia: Know this Before getting the Shot
By: Arlene Gentallan
Public expressed concern as the French drug maker Sanofi Pasteur announced last November 30, 2017 that the vaccine Dengvaxia isn't as safe as they first claimed it to be.
Dengvaxia, a 20 year undertaking to prevent the mosquito-transmitted disease dengue, can lead an individual to develop a severe form of dengue if they have not yet been previously infected by dengue.
Sanofi clarified that Dengvaxia does not cause dengue infection. Receiving dengvaxia shot will however, increase the chance that an individual will have a severe form of infection should they be infected with dengue for the first time.
Dengue has 4 strains of virus. It is known that a person develops a life-long immunity against a specific strain from prior infection. But, a reinfection of dengue from another strain will result to a more serious infection.
Study has shown that those individuals with previous dengue exposure who received dengvaxia were protected from dengue for 6 years and had less severe symptom in cases of succedding dengue reinfection.
