The loss of our historical memory or perspectives of massive outbreaks of diphtheria, and children dying from tetanus or being maimed by polio has probably made many of us unappreciative of the need for vaccination. Helping us understand more about the development of research into vaccines over the years is Dr Adriano Arguedas, Paediatric Infectious Diseases Specialist, and Dr Rohani Jahis, Head of Vaccine Prevention of Diseases Sector, Ministry of Health. This show is brought to you in collaboration with Pfizer Malaysia.
