Introduction The establishment of an immortalized continuous cell line derived from quail cells was undertaken by Baxter in order to develop a new cell line platform for vaccine production that is free of genetically modifying sequences. Important vaccines and viral vectors are still produced in embryonated chicken eggs or primary chicken embryo fibroblasts. However, the substitution of primary...

ontology is a requirement engineering product and the key to knowledge discovery. it includes the terminology to describe a set of facts, assumptions, and relations with which the detailed meanings of vocabularies among communities can be determined. this is a qualitative content analysis research. this study has made use of ontology for the first time to discover the knowledge of vaccine in ir...

PT Bio Farma, the sole World Health Organization-approved Indonesian vaccine producer, manufactures a whole-cell whooping cough vaccine (wP) that, as part of a pentavalent diphtheria-tetanus-pertussis/hepatitis B/Haemophilus influenzae b (DTP/HB/Hib) vaccine, is used in Indonesia and many other countries. We report here the whole-genome sequence for Bordetella pertussis Pelita III, PT Bio Farma...

A semi-synthetic culture medium and method are described for the production of a reduced dose Clostridium chauvoei vaccine. The vaccine gave excellent results in guinea-pigs, and 2 injections of 2.0 ml protected cattle against challenge with 2 M.L.D. of a virulent culture for at least 12 months. The suitability of C. chauvoei Strain OP64 as a vaccine strain was confirmed.

Cytomegaloviruses (CMVs) are members of the Betaherpesvirinae subfamily of the Herpesviridae, and their properties of latency, large DNA size, gene redundancy, and ability to be cloned as bacterial artificial chromosomes (BACs) suggest their utility as vaccine vectors. While the K181 strain of murine CMV (MCMV) is widely used to study MCMV biology, a BAC clone of this virus had not previously b...

Influenza vaccination is recognized as the most effective method for reducing morbidity and mortality due to seasonal influenza. To improve vaccine supply and to increase flexibility in vaccine manufacturing, cell culture-based vaccine production has emerged to overcome limitations of egg-based production. The switch of production system and the need for annual re-evaluation of vaccines for the...

As companies, countries, and governments consider investments in vaccine production for routine immunization and outbreak response, understanding the complexity and cost drivers associated with vaccine production will help to inform business decisions. Leading multinational corporations have good understanding of the complex manufacturing processes, high technological and R&D barriers to entry,...

In recent years the safety of the yellow fever live vaccine 17D came under scrutiny. The focus was on serious adverse events after vaccinations that resemble a wild type infection with yellow fever and whose reasons are still not known. Also the exact mechanism of attenuation of the vaccine remains unknown to this day. In this context, the standards of safety and surveillance in vaccine product...
