Novel vaccines : what's in the pipeline?

Abstract

Scientists worldwide are striving without heed in order to develop new vaccines which protect the human race against old and emerging diseases. However it is not only the menu of these vaccine preventable diseases which is being extended but the quality and efficacy of these vaccines are improving tremendously. Researchers are today studying vaccine adjuvants which improve the immunogenicity of the product, aiming to create a vaccine which provides lifelong immunity and which is well tolerated and free from side effects. The problem of the pin cushion effect with multiple injections during one and subsequent visits to the family doctor and pediatrician will soon be a thing of the past with the introduction of combination vaccines. Also in the twenty first century the use of edible vaccines, nasal sprays or skin lotions may eliminate the use of needles completely.
