1978 Expanded Programme of immunization (EPI).Limited reach - mostly urban

1985 Universal Immunization Programme (UIP). For reduction of mortality and morbidity due to 6

VPD’s.Indigenous vaccine production capacity enhanced

Cold chain establishedPhased implementation - all districts covered by 89-

90Monitoring and evaluation system implemented

Implementation of National Immunization Implementation of National Immunization ProgrammeProgramme

District is treated as administrative unit – 593Primary Health Centers are the last vaccine storage points - 23,109Services are provided through 142,655 sub centers to the population residing in about 638,588 villagesTarget for immunization is to cover infant population of over 25 million and around 27 million pregnant women

Immunization services are being provided through the existing health care delivery system. There is no separate staff required for the programme.

Pulse Polio Immunization Programme was launched in the country in the year 1995. Under this, under 5’s are given additional oral polio drops in December and January every year on fixed days.As a result, there has been a significant decline in the incidence of poliomyelitis.

Those outside rings are not vaccinated.

Primary Vaccination Ring

Secondary Vaccination Ring

Immuno-biological substances designed to produce specific protection against a given disease.

*Nowadays vaccines are of sub-unit and recombinant types.Administration: SUBCUTANEOUS & INTRAMUSCULAR

Live Vaccines—BCG, MMR*Not for immunologically challenged.

Inactivated(Killed)—iPV, Hepatitis B

Toxoids—Diphtheria, Tetanus

Immunoglobulins are for passive immunization!5 Major classes include- IgG, IgM, IgA, IgD, IgE.

TYPES:Normal Human ImmunoglobulinSpecific Human Immunoglobulin*These are used to replace antibodies in immunodeficient patients.Administration: INTRAMUSCULAR & INTRAVENOUS

LIVE VACCINE KILLED VACCINE TOXOIDSBCG, POLIO, MMR PERTUSSIS, TYPHOID, CHOLERA DIPHTHERIA, TETANUS

Vaccines have lost their capactiy to produce full-blown disease, retain immunogenicity.

*NOT to be administered to persons with immune deficiency diseases, suppressed immunity.

*NOT to be administered to pregnant women unless risk of infection exceeds risk of harm to fetus with live vaccine.

It stimulates active immunity. Usually safe but less efficacious than live vaccines. Also requires frequent booster doses.

*NOT to be given when there may be or was severe local or general reaction to a previous dose.

Exotoxins produced by organisms are detoxicated and used in preparation of vaccines. Antibodies produced neutralise the toxic moiety produced during infection, rather than act upon the organisms.

HIGHLY EFFICACIOUS.

Materials prepared in animals. Antitoxins prepared from non-human source s include: Tetanus, Diphtheria, Botulism, Gas gangrene, Snake Bite.

COLD CHAIN?A system of storage and transport of vaccines at low temperature from the manufacturer to the actual vaccination site.

Full Immunization Coverage by States (in %)

Coverage evaluation shows a varied coverage among the States. While the Southern States have been consistently achieving high coverage levels, the situation in Northern States is a matter of concern.

Performance under Immunization Programme

ConcernsConcernsLarge birth cohort - 25 million births every year

Declining coverage in some major states• An average of 14.4 % children receiving BCG do not receive

measles vaccine

Poor immunization data quality• Discrepancies between reported and surveyed data

Varied program management and supervision at all levels

Unsafe injection practices and waste disposal:

Significant percentage of injections used in the immunization sector are unsafe Low priority on medical waste disposal

The virus is also present in body fluids and excretions such as saliva, breast milk, semen, vaginal secretions, urine, bile and feces.Semen and Saliva are known culprits for transmission.

Target Population Dose Status

Percutaneous or mucosal exposure

0.05-0.07 ml/kg body wtRepeat after a month

Recommended For Prevention

Newborns of mothers with HBsAg

0.05 ml/kg body wtAt birth, 3 & 6 months

Recommended For Prevention

Immunization against Hepatitis has become an interesting addition to the UIP in India.

Ian Before Ian After

i. Test for Sensitivity Reactionii. Adrenaline (1:1000 solution) to be kept ready.iii. Properly sterilize equipment and apparatus.iv. Measles and BCG vaccines to be reconstituted

only with diluents supplied by manufacturer.v. Reconstituted Vaccines must NEVER be

retained for subsequent use.vi. Don’t store anything else in the refrigerator

other than vaccines.

Have a Great Day!
