Assignment: Universal Immunization Schedule for Pediatric Nursing

1. Introduction

Immunization is one of the most cost-effective public health interventions available. The Universal Immunization Programme (UIP) of India is the world's largest public health programme, targeting approximately 26.7 million newborns and 30 million pregnant women annually. It aims to reduce mortality and morbidity from vaccine-preventable diseases in children and expectant mothers.

2. Historical Background and Evolution

The concept of universal immunization evolved through several milestones:
YearMilestone
1962BCG introduced in India (National TB Programme)
1974WHO launched Expanded Programme on Immunization (EPI) - targeting 6 diseases: diphtheria, pertussis, tetanus, polio, tuberculosis, measles
1978India launched EPI (BCG, DPT, OPV, typhoid - urban areas)
1983TT vaccine introduced for pregnant women
1985Universal Immunization Programme (UIP) launched (Nov 19, 1985), dedicated to Smt. Indira Gandhi; measles added, typhoid removed
1990Vitamin-A supplementation added
1995Pulse Polio Immunization Programme launched
1997Vaccine Vial Monitor (VVM) introduced in UIP
2002Hepatitis B introduced (pilot in 33 districts)
2005National Rural Health Mission launched; auto-disable (AD) syringes introduced
2011Pentavalent vaccine introduced (DPT + Hep B + Hib)
2015IPV (Inactivated Polio Vaccine) introduced
2017MR (Measles-Rubella) vaccine introduced
2020PCV (Pneumococcal Conjugate Vaccine) and Rotavirus vaccine expanded nationally
2026Full immunization coverage reached 98.4% (January 2026)

3. Objectives of the Universal Immunization Programme

  1. Reduce mortality and morbidity from vaccine-preventable diseases in children under 1 year and pregnant women.
  2. Achieve universal immunization coverage for all eligible children and pregnant women.
  3. Maintain high-quality cold chain infrastructure for vaccine storage and delivery.
  4. Strengthen disease surveillance through reporting of Adverse Events Following Immunization (AEFI).
  5. Eradicate polio, eliminate measles, and reduce the burden of other vaccine-preventable diseases.

4. Diseases Covered Under UIP (2025-26)

The current UIP protects against 12 vaccine-preventable diseases:
  1. Tuberculosis (BCG)
  2. Diphtheria
  3. Pertussis (Whooping Cough)
  4. Tetanus
  5. Poliomyelitis
  6. Hepatitis B
  7. Haemophilus influenzae type b (Hib)
  8. Measles
  9. Rubella
  10. Japanese Encephalitis (endemic districts)
  11. Rotavirus diarrhea
  12. Pneumococcal disease (PCV)

MeningococcalSpecific settings (hostels, crowded)
HPVGirls 9-14 years (cervical cancer prevention)

7. Key Vaccines - Individual Notes for Nursing

BCG (Bacillus Calmette-Guerin)

  • Disease prevented: Tuberculosis (severe forms - miliary TB, TB meningitis)
  • Type: Live attenuated bacterial vaccine
  • Dose: 0.1 ml intradermal (0.05 ml in neonates < 1 month)
  • Site: Left upper arm
  • Important: Never give BCG to children above 1 year of age. A small wheal of 5-8 mm should form at the site; this is normal.

OPV (Oral Polio Vaccine)

  • Disease prevented: Poliomyelitis
  • Type: Live attenuated (bivalent - types 1 and 3)
  • Note: India was certified polio-free on March 27, 2014. OPV continues as eradication/maintenance measure.

IPV (Inactivated Polio Vaccine)

  • Introduced: November 30, 2015 (as part of Polio Endgame Strategy)
  • Fractional dose: 0.1 ml intradermal at 6 and 14 weeks
  • Purpose: Provides immunity against poliovirus type 2 (after type-2 component removed from tOPV)

Pentavalent Vaccine

  • Contains: DPT + Hepatitis B + Hib (5 antigens in 1 injection)
  • Advantage: Reduces the number of injections per visit
  • Note: Replaces separate DPT and Hepatitis B vaccines in the schedule

Measles-Rubella (MR)

  • Type: Live attenuated
  • Site: Right upper arm, subcutaneous
  • Note: Second dose at 16-24 months provides >95% seroconversion

DPT (Diphtheria-Pertussis-Tetanus)

  • Route: Intramuscular into antero-lateral mid-thigh (NOT gluteal region - risk of sciatic nerve damage + poor immune response if given in fat)
  • Minimum gap between doses: 4 weeks
  • Upper age limit: 7 years for DPT; switch to Td/TT at 10 years
  • Contraindication: History of encephalopathy after previous DPT - give DTaP or DT instead

8. Cold Chain Management

The cold chain is a system of storing and transporting vaccines at recommended temperatures (2-8°C) from manufacture to administration. This is critical because most vaccines are irreversibly damaged by heat or freezing.

Cold Chain Equipment

  • Walk-in cold rooms (WIC) and walk-in freezers (WIF) - national level
  • Deep freezers (-25°C to -15°C) - district level
  • Ice-lined refrigerators (ILR) (2-8°C) - PHC level
  • Vaccine carriers with ice packs - outreach sessions

Cold Chain Do's and Don'ts (Nursing Practice)

Do's:
  • Check expiry date and Vaccine Vial Monitor (VVM) label before every administration
  • Keep vaccines and diluents in a plastic/zipper bag in the centre of the vaccine carrier with 4 conditioned ice packs
  • Ensure diluents are also at 2-8°C before reconstitution
  • Keep reconstituted BCG and Measles vaccines on top of the ice pack
  • Discard opened vials of BCG and MR at the end of the immunization session
Don'ts:
  • Do not leave vaccine carrier in sunlight
  • Do not leave the lid open
  • Do not keep DPT, DT, TT, and Hepatitis B vaccines directly on the ice pack (freeze-sensitive vaccines)
  • Do not carry vaccines in a handbag
  • Do not use vaccines with a VVM that shows the inner square darker than the outer circle

9. Nursing Responsibilities During Immunization Sessions

Before the Session

  1. Prepare beneficiary list (mother and child register)
  2. Verify vaccine stocks, check expiry dates and VVM labels
  3. Ensure cold chain equipment is functioning
  4. Prepare injection equipment (AD syringes, safety boxes)
  5. Prepare the immunization area and inform the community

During Administration

  1. Welcome beneficiaries warmly
  2. Wash hands before conducting each session
  3. Verify beneficiary's record and the child's age
  4. Screen for contraindications (see below)
  5. Check label and expiry date of the vial
  6. Lightly shake T-series vaccine vials (DPT, TT) before drawing dose
  7. Use a new AD (auto-disable) syringe for each injection; use a new disposable syringe for each reconstitution
  8. Use the correct diluent for reconstitution (BCG uses only the supplied diluent)
  9. Inject at the correct site and route for each vaccine
  10. Allow dose to self-disperse - do NOT massage the site
  11. Do NOT clean the injection site with a spirit swab - alcohol kills live vaccine components
  12. Explain potential AEFI and what to do
  13. Record in vaccination card and register
  14. Discuss the next visit date with parents

After the Session

  1. Safely dispose of sharps in safety boxes
  2. Return unused vaccines to cold chain with proper documentation
  3. Discard opened vials of BCG, MR, and Rotavirus
  4. Multi-dose vials of DPT, DT, TT, OPV, Hepatitis B can be used up to 4 weeks if VVM is in range and stored properly
  5. Report AEFI to the block/district level

10. Contraindications to Vaccination

VaccineContraindication
All vaccinesAnaphylaxis/severe allergy to previous dose or vaccine component
BCGSymptomatic HIV, known immunodeficiency
DPTEncephalopathy within 7 days of previous DPT dose - give DT/DTaP instead
Live vaccines (OPV, MR, BCG, Varicella)Primary immunodeficiency states
OPVHIV-positive contacts in household - use IPV instead

Conditions That Are NOT Contraindications (Common Myths)

  • Mild illness (cold, cough, low-grade fever, diarrhea) - vaccination should proceed
  • Malnutrition - vaccine is safe and more important
  • Stable neurological conditions
  • Low-birth-weight/premature infants at the time they reach scheduled age
Nurses must never withhold vaccines for minor illness. Missed opportunities lead to outbreaks.

11. Vaccine Vial Monitor (VVM)

The VVM is a heat-sensitive sticker on each vaccine vial. It helps field workers determine whether a vaccine has been damaged by heat.
  • Inner square lighter than outer circle = vaccine is still usable
  • Inner square darker than or same color as outer circle = vaccine MUST NOT be used (discard)

12. AEFI - Adverse Events Following Immunization

AEFI is any untoward medical occurrence which follows immunization and does not necessarily have a causal relationship.

Categories

  1. Vaccine-induced - febrile convulsions after DPT, vaccine-associated polio (VAPP)
  2. Vaccine-potentiated - underlying condition unmasked by vaccine
  3. Programmatic errors - wrong dose, wrong site, use of contaminated diluent
  4. Coincidental - event that would have occurred regardless of vaccination

Common AEFIs by Vaccine

VaccineCommon AEFIRare/Serious AEFI
DPTLocal pain, swelling, feverConvulsions, hypotonic-hyporesponsive episode, anaphylaxis
BCGLocal ulcer, regional lymphadenopathy (BCGitis)Disseminated BCG disease (in immunocompromised)
OPVUsually noneVAPP (1:750,000 first doses)
MR/MeaslesMild fever, rash at 5-12 daysFebrile seizures (rare)
Hepatitis BLocal sorenessRare

AEFI Reporting

  • Report all serious AEFIs to the Medical Officer/District Immunization Officer immediately
  • Fill AEFI reporting form and investigate causality
  • India has an active AEFI surveillance system under MoHFW

13. Missed/Late Doses - Catch-Up Vaccination

  • Do NOT restart the schedule even if a child is brought late for a dose
  • Pick up where the schedule was left off (e.g., if DPT-2 was missed, give DPT-2 on return)
  • Minimum intervals between doses must still be observed (minimum 4 weeks between DPT doses)
  • DPT can be given up to 7 years of age; OPV up to 5 years; BCG up to 1 year

14. Pulse Polio Programme (National Immunization Days - NIDs)

Launched in 1995 under UIP:
  • Children under 5 years receive additional OPV drops (regardless of prior immunization status)
  • Conducted on fixed days in December/January every year
  • House-to-house vaccination introduced in 1999-2000 for missed children
  • Result: India certified polio-free on March 27, 2014

15. Mission Indradhanush

A special campaign launched in 2014 to fully immunize children who were unvaccinated or partially vaccinated. Targets children under 2 years and pregnant women missed by routine immunization. Intensified Mission Indradhanush (IMI) phases have consistently improved coverage, with full immunization rising from 62% (2015) to 98.4% as of January 2026.

16. Nursing Diagnosis Related to Immunization

  1. Risk for infection related to incomplete immunization status
  2. Deficient knowledge (parents) related to immunization schedule, benefits, and side effects
  3. Anxiety (child/parent) related to immunization procedure
  4. Risk for AEFI related to vaccine administration
  5. Non-compliance related to cultural beliefs, lack of access, or misinformation

17. Health Education for Parents (Nursing Role)

  1. Explain the benefits of each vaccine and the diseases it prevents
  2. Reassure that minor reactions (low-grade fever, local swelling) are normal and self-limiting
  3. Advise to give paracetamol if fever develops after vaccination
  4. Emphasize importance of completing the full schedule
  5. Explain that mild illness is NOT a reason to skip vaccination
  6. Show how to read the vaccination card and the next due date
  7. Inform about when to seek medical help (high fever >103°F, persistent crying, convulsions)
  8. Address vaccine hesitancy with evidence-based communication

18. Summary

The Universal Immunization Programme of India is a landmark in global public health. As a pediatric nurse, understanding the complete immunization schedule, proper vaccine administration techniques, cold chain management, AEFI recognition, and effective parent education are all essential competencies. Every contact with a child and family is an opportunity to assess and update immunization status - missed opportunities must be prevented.
