Children over 11 years of age are advised to receive one dose of the modern vaccine. There are currently no recommendations for dosages. Immunization is based on scientific studies for 3-5 years after the old vaccine is given and immunity is expected to last longer with use of the modern vaccine. The vaccine is also recommended for children between the ages of 2 and 11 who suffer from immune system dysfunction or spleen function and in adults who travel to areas where the incidence of the epidemic is high, such as those going to the Hajj or to Africa.
