Combination Vaccines

Infections are still a leading cause of morbidity and mortality in children under five years of age, most of which can be prevented by vaccination. However, there are too many vaccines to be administered, increasing the cost of immunization and visits to the paediatrician. Combination vaccines can be an answer to these problems till the development of a single vaccine containing all the possible antigens. Researchers are aiming at development of an ideal vaccine, which can be given orally at birth, has negligible side effects, is heat stable and is affordable to all the parents.
