I REFER to the letter “Dengue vaccine strategy” (The Star, April 21), where the writer said “What we may be able to expect are reductions in severe disease, reduced hospitalisation due to dengue and possibly a reduction in deaths due this dreaded mosquito-borne disease.”

While it is indeed true about what this Dengvaxia vaccine can do for us, it must be remembered that all cases of the disease must be hospitalised to isolate (for the period of communicability, which is usually five days) such cases in special dengue wards to prevent the spread of the disease.
