Recommended Action
Management		Live, attenuated oral typhoid vaccine should not be administered during and for at least 3 days before and after treatment with antibacterial sulfonamides or other antibiotics. A longer interval should be considered following treatment with long-acting antibiotics (e.g., azithromycin). If malaria prophylaxis is needed, the same 3-day interval at the minimum should be observed between antimalarials and the vaccine. However, chloroquine, mefloquine, and pyrimethamine-sulfadoxine may be given concomitantly with the vaccine. alternatively, parenteral typhoid vaccine (typhoid Vi polysaccharide vaccine) may be considered if coadministration with antibacterial agents is required.
