They haven't yet developed anything of the kind, if it is based on their Dengue and Chikungunya vaccines, vaccines unable to exit clinical testing. Most optimistically, their Zika vaccine is still a year to 2 years out once they finish preclinical work.

Promising Dengue vaccines have been in development for 25 years and the most promising have failed to exit Phase 3. The reasons are not tox but rather (1) a failure to achieve a response and protection in sufficient numbers of those vaccinated and (2) reversion to wild virus (a percentage of those vaccinated get Dengue from the inoculation) in attenuated live virus type vaccines which are the most effective against Dengue.

These are tough viruses.
