Dsp of vaccine

  1. 1. A SEMINAR ONDownstream processing of vaccine (e.g. Influenza & Tetanus) Presented By- NIYAMAT M. PANJESHA SNEHA SAWLE YUGENDRA PATIL Modern College Of Arts , Science & Commerce. Shivajinagar, Pune-05.
  2. 2. What are Vaccines?• A vaccine is a biological preparation that improves immunity to a particular disease.• Name derived from the word vacca which means cow.• Can be- 1) Prophylactic. 2) Therapeutic. Edward Jenner observed that the farmers and milkmaids working with cows developed a mild form of small pox called cowpox or vaccinia. The cowpox infection could protect these people from infection of smallpox. It was in 1796 Jenner experimentally tested this observation. He inoculated an 8 yr old boy with exudates from a cowpox lesion and he repeated it twice with a gap of some weaks. Jenner noticed that smallpox did not develop in this boy. This was 1st discovery of principle of vaccination.

  7. 7. Influenza VaccineTwo modes: Seasonal Epidemic andPandemic InfluenzaTypes of VaccineProduction:1.Egg based(Traditional)2.Cell line basedThree forms of vaccine:A.WholeB.SplitC.Subunit/Surface Antigen
  8. 8. Live Virus Vaccine Production using MDCK cell line onCytodex3 micro carrier Upstream Process:0.5X106 cells/ml(at 100r.p.m. for 48hrs.) At 2-2.5X106 cells/ml infectwith Viral inoculum and carry out for 24hr.
  9. 9. DOWNSTREAM PROCESSING1.Clarification:ULTA Prime GF capsuleFiltration(0.6µm)2.Diafiltration(0.4µm) inbuffer[20mM Tris+0.5M NaCl,pH7.5]3.DNA binding Anion ExchangeChromatography: To remove gDNA4.Sterile Filtration(0.2µm):Stainless steel filter precoated withbuffer.
  10. 10. Tetanus is an acute and highly fatal disease caused byexotoxins produced by the bacterium Clostridium.tetani.Cl. tetani produces two exotoxins- tetanolysin andtetanospasmin.Tetanus toxoid is one of the most immunogenicantigens available for the protection against an infectiousdisease in the world.Tetanus Vaccine produced by anaerobic fermentation.
