• Immunization-
  – Immunization is the process whereby a
   person is made immune or resistant to an
   infectious disease, typically by the
   administration of a vaccine.

• Vaccine-
   A vaccine is any preparation intended to
  produce immunity to a disease by
  stimulating the production of antibodies..
Immunizing agents
1) Vaccines
• Live attenuated:
      Bacterial: BCG, Typhoid, plague
      Viral :   Oral polio , Yellow fever, Measles, Mumps,

                 Rubella, Influenza
• Inactivated or killed vaccines
     Bacterial: Typhoid, Cholera, Pertusis, Plague
     Viral :    Rabies, Salk (Polio), Influenza , Hepatitis B,

                Japanese encephalitis

2) Toxoids : Diphtheria, Tetanus
Physiological basis

– CELL-MEDIATED IMMUNITY
Antibody response after exposure
Central Role of Helper T Cells
ADJUVANTS




A vaccine adjuvant is a component that potentiates the
immune responses to an antigen and/or modulates it
towards the desired immune responses.
Aims of immunization
• Eradication
  – State where disease and its causal agent have been
    removed from natural environment
• Elimination
  – Reduction to zero cases or reduction in indegineous
    sustained transmission of infection in geographical
    region.
• Control
  – Reduction of illness outcomes and limitation of the
    disruptive impacts associated with outbreaks of
    disease in communities, schools, and institutions.
Why we need adult vaccines ?
Burden of Adult Vaccine-Preventable Disease

 Influenza:        10-20% of US population annually
                   200,000 hospitalizations
                   36,000 deaths (average)

 Pneumococcal:     2,000-5000 meningitis
                   40,000+ bloodstream infections
                   150,000-300,000 pneumonia

 Pertussis:         1 million
 Cervical cancer:   10,000
 Shingles:          1 million
 Death from vaccine-preventable diseases: 43,000
WHY ADULTS?
The burden

Vaccination gap

High risk group

Chronic medical conditions

•    Vaccine was found to be 33% effective in preventing
    total respiratory illness (influenza-like illness and
    clinically diagnosed pneumonia). In prevention of
    pneumonia alone, vaccine was 43% effective. The
    estimate for prevention of pneumonia rose to 55% if the
    period under consideration was limited to the time of
    peak influenza activity. Given the number of eligible
    homes and the cohort methodology used, the results
    support continuation of current policy, encouraging use
    of vaccine in all nursing home residents.

Harrison figure




Changes in invasive pneumococcal disease (IPD) incidence, by serotype group,
among children <5 years old (first) and adults >65 years old (second), 1998–2007.
*7-Valent pneumococcal conjugate vaccine (PCV7) was introduced in the United
States for routine administration to infants and young children during the second half
of 2000. (Reprinted with permission from Pilishvili et al, 2010.)
Conclusion
The recent introduction of universal PCV vaccination in children has led
to a change in the epidemiology of IPD in adults. The incidence of IPD
associated with PCV serotypes is expected to decrease and that
associated with other serotypes is expected to increase in adults.
Despite a reduction in the incidence of IPD, vaccinating the elderly and
at-risk adults with PPV23 in Germany against IPD and NBPP remains a
cost-effective strategy because of its broad serotype coverage.

Editor's Notes

  • #40 Twinrix ® is a combined hepatitis A and hepatitis B vaccine approved in 2001 by the Food and Drug Administration (FDA) for persons 18 years of age or older. Twinrix ® contains 720 EL.U. of hepatitis A antigen and 20 μg of hepatitis B surface antigen. Primary immunization consists of three doses, given on a 0-, 1-, and 6-month schedule, the same schedule as that used for single - antigen hepatitis B vaccine. Immunogenicity of the combined vaccine appears to be similar to that of the single - antigen vaccines when given separately. Twinrix ® can be used for immunization of persons 18 years of age or older who have indications for vaccination against both hepatitis A and hepatitis B, such as users of illicit injectable drugs, men who have sex with men, and persons with clotting factor disorders who receive therapeutic blood products. Formulation for children is available in many other countries. For international travel, hepatitis A vaccine is recommended for travelers to areas of high or intermediate hepatitis A endemicity (see slide 10). Hepatitis B vaccine is recommended for travelers to areas of high or intermediate hepatitis B endemicity who plan to live or work for at least 6 months in highly endemic countries (see slide 9 in hepatitis B slide set at http://www.cdc.gov/ncidod/diseases/hepatitis/slideset/hep_b/slide_9.htm).
