Sylvie, you are probably thinking about the malaria alert in the Altagracia Province from December 99 until February 00. There are no such alerts any longer. The problem has been dealt with and there is no recommendation of malaria prophylaxis when going to the DR.
When I'm in the D.R. I live out of the resorts in the rural area so my vaccinations are up to date and I do take Aralen against the malaria. Just to be on the safe side contact your C.L.S.C. If you're in Montreal contact the D?partement de sant? communauraire de l'H?pital St-Luc (514) 281-3295. Some vaccines are free others are not.
