Dengue Vaccine?
- No licensed vaccine
at present
- Effective vaccine
must be tetravalent
- Field testing of
an attenuated tetravalent vaccine currently underway
- Effective, safe
and affordable vaccine will not be available in the immediate future
There is now no licensed dengue vaccine available. An effective
vaccine must be tetravalent, providing protection against all
four serotypes, because pre-existing heterotypic dengue antibody
is a risk factor for DHF. Field testing of an attenuated tetravalent
vaccine in currently occurring in Thailand. However, an effective,
safe and affordable vaccine is not likely to be available in
the immediate future. |
