An International Vaccine symposium titled 'Vaccines from Discovery to Translation' will begin in New Delhi tomorrow. According to an official release, more than 100 world-leading experts from disparate fields of vaccinology in both its human and veterinary domains will participate in the four day event. They will put forward valuable ideas and approaches among researchers often narrowly focused on their specific diseases or methods. It is a first of this kind of meeting in India. The meeting is exclusively devoted to research on vaccines and associated technologies for disease prevention and treatment through immunisation.
