Immunisation.

Dr. Mark Porter looks at vaccinations. He learns about the new flu jab and finds out about changes to routine childhood vaccinations. He is joined by Dr David Elliman, Community Paediatric Consultant at Great Ormond Street Hospital who describes the new childhood immunisation against pneumonia and meningitis. Dr Doug Jenkinson from the Keyworth Health Centre in Nottingham describes the whooping cough vaccination and Dr Porter visits the National Institute for Biological Standards and Control to find out how laboratories and drug companies grow the viruses needed to create new vaccines.
