The document discusses the Expanded Program on Immunization (EPI) which aims to make vaccines available to all children worldwide. It was launched by the WHO in 1974 to immunize against six preventable diseases. The EPI schedule in Pakistan aims to reduce mortality from seven target diseases by vaccinating children aged 0-11 months and women of childbearing age. Vaccines included in the schedule are BCG, OPV, DPT, measles, and more recently pneumococcal vaccine. The goals of EPI in Pakistan include achieving 100% coverage with all vaccines, eliminating polio and measles, and reducing disease incidence. Progress has been made through improved routine immunization, campaigns, and strengthening of surveillance, cold chain

(EPI(EPI))

3.  Expanded program on Immunization (EPI) is a world
health organization program, with the goal to make
vaccines available to all children throughout the world.

4.  Experience with smallpox eradication program showed the
world that immunization was the most powerful and cost-
effective weapon against vaccine preventable diseases.
 In 1974, the WHO launched its “ Expanded program of
immunization” (EPI) against six most common preventable
diseases (diphtheria, pertussis, tetanus, polio,
tuberculosis, measles and recently added pneumococcal
vaccine).

5.  Expanding the number of diseases to be covered
 Expanding the number of children and target
population to be covered
 Expanding coverage to all corners of the country
and spreading services to reach the less privileged
sectors of the society.

6. Routine Immunization:
 Children 0-23 months – immunization with 8 EPI antigens
 Pregnant ladies by TT.
Supplemental Immunization Activities:
 Routine immunization does not ensure 100% coverage of the mobile
population i.e. nomads, NAs, hard to reach areas / missed areas. So SIAs
are scheduled to ensure coverage of this population / areas.
 NIDs / SNIDs: children < 5 years receive polio drops (3-days campaign)
Disease Surveillance:
 To detect every case of target diseases, the suspected cases of seven
VPDs are reported by health facilities to the district health authorities for
immediate launching of the control measures.
Mopping up:
 Special campaigns 5-8 km around the infected locality to localize the
disease and stop its transmission.

7. 1. To achieve 100% coverage with all EPI vaccines.

8. 2. Eradication of polio to maintain polio free status.

9. 3. Elimination of measles.

10. 4. To Reduce Seroprevalence Of HBsAg to < 1%
among under five.

11. 5.Elimination of Neonatal Tetanus .

12. 6. To maintain zero level of diphtheria.

13. 7-Prevention of severe forms of TB ( TB meningitis &military
TB).

14. 8- To reduce the incidence of whooping
cough

15. 9- To Reduce the incidence of Bacteria Meningitis due9- To Reduce the incidence of Bacteria Meningitis due
to haemophelus influenza.to haemophelus influenza.

16. 10- To Maintain Immunization Safety.

17. 11-To prepare for introduction of new vaccines

19.  Expanded program on immunization was launched in Pakistan in
1978.
 The purpose of EPI is to initiate a collective effort to reduce the
mortality results from the seven EPI target disease by immunizing
children of the age 0-11 months and women of child bearing age.
 Although Pakistan has made impressive gains in increasing the EPI
coverage in the recent years ,the public awareness and thus public
support and participation in immunization derives of the ministry of
health, government of Pakistan needs to improve further to enable
us to achieve the target set under the Millennium developmental
Goals.

20.  Reduction of mortality and morbidity resulting from 7 EPI target
diseases by immunizing children of age 0-11months and women of
child bearing age.
 90% routine immunization coverage of all EPI antigens by 2012.
 Interruption of polio virus transmission by 2012
 Elimination of the Neonatal Tetanus by 2015
 Reduction of The Diphtheria, Pertusis, Childhood TB, by maximum
level
 Control of the other diseases by Introduction of new vaccines EPI

37. Severe bacterial infection, particularly among infants
During late 19th century believed to cause influenza
Immunology and microbiology clarified in 1930s
 The type of Hib vaccine is inactivated
polysaccharide conjugated vaccine.
 It is made by joining of the polysaccharide
of Hib bacterium and protein carrier.
 Give all infants, including premature
infants, a primary series of Hib vaccine
beginning at the age of 2 months.
 Do not administer Hib prior to six month of
the age, because it will induce immunologic
tolerance to further dose of Hib vaccine.

38. Small child receiving Hib

43. Diphtheria causes a thick covering in the back of the throat.
It can lead to breathing problems, paralysis, heart failure,
and even death. There are several combination vaccines
used to prevent diphtheria: DTaP, DT, and Td.

44. Pertussis is a bacterial infection caused by Bordetella pertussis. The germ is
spread when infected people cough or sneeze.
Available Vaccines:
No pertussis-only vaccine is available. The pertussis vaccine is available as:
DTaP (Diphtheria Toxoid-Tetanus Toxoid-acellular Pertussis vaccine)
DTaP in combination with Haemophilus influenzae type b (Hib) vaccine
DTaP in combination with hepatitis B and inactivated polio vaccines

Mumps)
0.5 ml
Subcutaneous arm

48. Pneumonia — a bacterial infection in the lungs — is a
common complication from the flu. In addition to a flu
shot every fall, it's a good idea to get a once-in-a-lifetime
pneumococcal vaccine.

49. Pneumococcal vaccines. (Minimum age: 6 weeks for pneumococcal conjugate
vaccine [PCV]; 2 years for pneumococcal polysaccharide vaccine [PPSV]).
• Administer 1 dose of PCV to all healthy children aged 24 through 59 months
who are not completely vaccinated for their age.
• For children who have received an age-appropriate series of 7-valent
PCV (PCV7), a single supplemental dose of 13-valent PCV (PCV13) is
recommended for:
— All children aged 14 through 59 months
— Children aged 60 through 71 months with underlying medical conditions.
• Administer PPSV at least 8 weeks after last dose of PCV to children aged 2
years or older with certain underlying medical conditions, including a cochlear
implant

52.  Acute diarrhoea is responsible
for nearly 1.9 million deaths per
year in children under age five.
 Rotavirus is responsible for as
much as one fourth of these
casualties, almost all of which
occur in developing countries.

53.  Rotavirus (RV) vaccines. (Minimum age: 6 weeks for both RV-1
[Rotarix] and RV-5 [Rota Teq])
 The maximum age for the first dose in the series is 14 weeks, 6
days; and 8 months, 0 days for the final dose in the series.
Vaccination should not be initiated for infants aged 15 weeks, 0
days or older.
 If RV-1 (Rotarix) is administered at ages 2 and 4 months, a
dose at 6 months is not indicated.

55.  80.2 %( 0-11 months) children fully immunized (CES-2006).
 35.8 Million Children immunized against measles through special
campaign in 2008.
 TT Immunization to target women (15-49 yrs.) in 6 high risk Districts in
Punjab.
 Vitamin-A supplementation –twice a year with coverage >95%.
 Storage capacity enhanced for the buffer stocks of all vaccines for the
period of 3 months.
Improved monitoring & supervision through
 Provision of 59 single cabin vehicles for DO(H) under GAVI.
Provision of 3652 motorcycles to EPI staff under GAVI.
Provision of cold chain equipment to 8 flood hit districts.
Capacity building of health managers and EPI staff, (17,804).
Orientation training workshops for medical officers LHVs, LHWs, etc.
Training of health personnel for cold chain repair and maintenance.
Training workshops for vaccine stock management carried out in all
districts during 2010, 2011 and 2012.
