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

vaccine must be tetravalent, providing protection against all
four serotypes, because pre-existing heterotypic dengue antibody

vaccine in currently occurring in Thailand. However, an effective,
safe and affordable vaccine is not likely to be available in
the immediate future. |
