  • The efficacy or performance of the vaccine is dependent on a number of factors: the disease itself (for some diseases vaccination performs better than for others) the strain of vaccine (some vaccines are specific to, or at least most effective against, particular strains of the disease) whether the vaccination schedule has been properly observed. (wikipedia.org)
  • The following are important considerations in the effectiveness of a vaccination program:[citation needed] careful modeling to anticipate the impact that an immunization campaign will have on the epidemiology of the disease in the medium to long term ongoing surveillance for the relevant disease following introduction of a new vaccine maintenance of high immunization rates, even when a disease has become rare. (wikipedia.org)
  • Vaccines are typically imperfect as some individuals' immune systems may not generate an adequate immune response to vaccines to confer long-term immunity, so a portion of those who are vaccinated may lack immunity.Lastly, vaccine contraindications may prevent certain individuals from becoming immune.

  • smallpox
  • The first clinical description of immunity which arose from a specific disease causing organism is probably Kitab fi al-jadari wa-al-hasbah ('A Treatise on Smallpox and Measles', translated 1848) written by the Islamic physician Al-Razi in the 9th century. (wikipedia.org)
  • Variolation had the disadvantage that the inoculating agent used was still an active form of smallpox and, although less potent, could still kill the inoculee or spread in its full form to others nearby. (wikipedia.org)
  • pathogen
