Typhoid:
Considering the high incidence of typhoid in our country, it would be worthwhile to administer this vaccine. Newer vaccines now available are administered as a single dose injection after two years of age. Boosters are necessary every 3 years. In a child more than 6 years old, an oral (capsule) preparation is available. This is given as a single capsule every alternate day for 3 doses. The oral vaccine also needs to be taken every 3 years for continued protection.
