  1. 1. A.E.F.I.Adverse Event Following Immunization
  2. 2. A.E.F.I. Why “event” – not “effect”? Event -vs- Effect (outcome of RI) Not desired desired /expected Unwanted wanted Eventful uneventful Warrants does not actions warrant actions More players Less players(people gets involved) (only beneficiary involved)
  3. 3.

  4. 4. Types of AEFIs• Program Errors• Vaccine reactions• Coincidental• Injection reaction• Unknown
  5. 5. Types of AEFI1. Programmatic Error• Due to error in vaccine preparation, handling or administration.• Majority of AEFIs occur due to programmatic errors – and preventable Non-sterile needle Suppurative Lymphadenitis following BCG Vaccination
  6. 6. Common programmatic errors which can lead to AEFIs Non-sterile injection  Contact of needle with unsterile surface e.g. finger, swab, table etc.Infection can manifest as:  Administering injection over clothesLocal reactionvaccine or diluent abscess  Contaminated – suppuration,  Use of reconstituted vaccines beyondSystemic effecthours the stipulated 4 – sepsis, toxic shock syndromeBlood borne virus infection at HIV, HBV, HCV  Reuse of reconstituted vaccine – subsequent sessions  Reuse of disposable syringe & needle Time ??
  7. 7. Common programmatic errors which can lead to AEFIsReconstitution error/ Wrong vaccine preparation Reconstitution with incorrect diluent - less vaccine effectiveness Drug substituted for diluent – drug reaction, death Inadequate shaking of T-series vaccines – local abscessInjection at incorrect site/route Injection into gluteal region (buttocks) – sciatic nerve damage BCG /T series vaccine given subcutaneously – local reaction or abscess
  8. 8. Common programmatic errors which can lead to AEFIsVaccine transportation/storage incorrect Administration of frozen and thawed freeze-sensitive vaccine -local reaction such as sterile abscessContraindications ignored DPT2 given after H/O convulsions with DPT1 - convulsions
  9. 9. Common program errors can be prevented by :-• training of H.W.• regular supervision• adequate supply / availability of logistics
  10. 10. …Types of AEFI2. Vaccine ReactionAn event caused or precipitated by the active component orone of the other components of the vaccine (e.g. adjuvant,preservative or stabilizer).This is due to the inherent properties of the vaccine.A. Common, minor vaccine reactions – local reaction (e.g. pain, swelling and/or redness, fever). - Local reactions and fever should be anticipated in only 10% of the vaccine recipients, except in the case of whole cell DPT which produces fever in nearly half of those vaccinated.
  11. 11. …Types of AEFI2. Vaccine Reaction - Fever and minor local and systemic reactions usually occur within a day or two of immunization (except for those produced by measles/MMR vaccine which occurs 6 to 12 days after immunization) and only last for few days. - Fever and minor local reactions can usually be treated symptomatically with paracetamol. - systemic symptoms (e.g. vomiting, diarrhoea, malaise)B. Rare serious vaccine reactions High (39-40.4oC / 102-104.7oF) to extreme fevers (>40.5oC/105 oF) indicate the possibility of: Anaphylaxis - potentially fatal allergic reaction, but treatable
  12. 12. …Types of AEFI3. Coincidental EventAn event that occurs after immunization but is not caused by the vaccine.This is due to a chance temporal associationExample: pneumonia after oral polio vaccine administration 4. Injection ReactionEvent caused by anxiety about, or pain from the injectionitself rather than the vaccineExample: fainting spell in a teenager after vaccination 5. Unknown Any event due to undetermined cause.

  17. 17. Treatment of AnaphylaxisAdrenaline (epinephrine) counters anaphylaxis.Keep emergency kit ready with adrenaline. kit should be checked three or four times a year. Adrenalinethat has a brown tinge must be discarded.Ensure the airway is clear. If appropriate, begin cardiopulmonary resuscitation.Give 1:1000 adrenaline at a dose of 0.01ml/kg up to a maximum of 0.5 ml by deep intramuscularinjection into the opposite limb to that in which the vaccine was given. (Subcutaneous administration isacceptable in mild cases).If the weight of the patient is unknown, an approximate guide is: Less than 2 years 2-5 years 6-11 years 11+ years 0.0625 ml (1/16th of a ml) 0.125 ml (1/8th of a ml) 0.25 ml (1/4 of a ml) 0.5 ml (1/2 of a ml)And give an additional half dose around the injection site (to delay antigen absorption).If the patient is conscious after the adrenaline is given, place his/her head lower than the feet and keep thepatient warm.Give oxygen by face mask.Call an ambulance (or arrange other means of transport, after the first injection of adrenaline. If there is noimprovement within 10-20 minutes, of the first injection, repeat the dose of adrenaline up to a maximum ofthree doses in total. Recovery from anaphylactic shock is usually rapid after adrenaline.At a suitable moment, explain to parents or relatives the importance of avoiding the vaccine in the future.
  18. 18. Reporting AEFIs Why report AEFIs ?• Effective means of monitoring immunization safety• Contributes to quality & credibility of program• Helps in clinical management of case• Identify gaps in program implementation (if any)• Helps identify actual rate of occurrence.• Avoids false rumors• Build confidence of public in program
  19. 19. Cluster of AEFIsA cluster is defined as two or more cases of the same orsimilar events, which are related in time, and have occurredwithin specific geographical area, or associated with thesame vaccine, the same batch number or the samevaccinator.e.g. two or more cases of abscess occur in a village following animmunization session Ormultiple abscess cases following immunization by the same vaccinator orthe same batch of the vaccine, but in different villages.

  27. 27. Investigating AEFIs• The focus of the investigation should be to confirm the working hypothesis.• Request laboratory testing only on a clear suspicion and not as routine, and never before the working hypothesis has been formulated• Laboratory testing may sometimes confirm or rule out the suspected cause.• The vaccine and diluent may be tested for sterility and chemical composition; and the needles and syringe for sterility.• Send unopened vaccine vials and matching diluent of the same batch for testing• Send vaccine samples for testing to the National Control Laboratory (NCL), Central Research Institute, Kasauli accompanied with a completed Lab Requisition Form (LRF) along with a copy of the available FIR/PIR. Send the samples in cold chain (+20C to +80C) and by fastest means.

  37. 37. Key reasons for under reporting• Fear/ apprehension to report.• Unaware about reporting system & process.• No technical committee to respond.• Not considering the event as related to immunization• Guilt about having caused harm and being responsible• Media fear• A nil report is also important.
  38. 38. AEFIs• Encourage Field workers to report AEFIs without fear of penalty.• The aim is to improve systems to prevent / minimize further AEFI and not to blame individuals.
  39. 39. Roles and ResponsibilitiesANMs should:• Ask the beneficiaries to wait for half an hour after vaccination to observe for any AEFI.• Leave the list of children vaccinated in a session with the AWW/ASHA and request them to be alert and report AEFIs. Share contact details of self and PHC.• Treat mild symptoms like fever, pain• Report deaths, injection site abscesses and other complications in the monthly UIP report. A nil report is also important.• Refer serious cases to MO (PHC) or to appropriate health facility for prompt treatment.• Report serious events/ cluster of events immediately to the supervisor/ MO (PHC)/ DIO• Record the time of opening/ reconstitution of vial on the vial label.• Communicate with parents and other members of the community• Assist in investigation of AEFIs
  40. 40. Roles and ResponsibilitiesHealth Supervisors should:• Collect and review reports of AEFIs during their supervisory visits to immunization session sites/ SC.• Provide on-the-job training to the field staff on safe injection practices and reporting.• Assist the MO in conducting the investigation.
  41. 41. Roles and ResponsibilitiesMO PHC/ CHC should: ANMs should:• Improve/arrange logistics to prevent AEFI due to program errors.• Train staff in detecting, managing and reporting of AEFIs• Manage AEFIs and refer to the higher level, if required.• Initiate investigation, when required• Complete case report forms (FIR, PIR and DIR) and inform the DIO immediately for serious cases and deaths• Report deaths, injection site abscesses and other complications in the monthly UIP report. A nil report is also important.• Supervise all reported AEFI through site visits and give immediate feedback to health workers.• Communicate with and share the conclusions and results of investigation with health workers and the community.
  42. 42. Roles and ResponsibilitiesAT DISTRICT LEVEL:• Establish district AEFI committee• Train field staff in managing, investigating and reporting AEFIs.• Identify a focal person for investigations.• Identify a designated spokesperson to address the media if required• Coordinate AEFI case management• Report ALL AEFIs - a nil report is also important.• Investigate serious AEFIs and deaths with State-level Investigation Teams• Send FIR, PIR and DIR of serious AEFIs
  43. 43. District AEFI Committee• CMOH• DIO• DFWO• Dy.CMOH-II (Epidemiologist)• Microbiologist / Pathologist• Paediatrician / Physician• DPHNO• IAP/IMA Representative• Assistant Drug Controller
  44. 44. State AEFI Committee• SEPIO• SRTL-NPSP (East)• Representative from WBSISC• Microbiologist / Pathologist• Paediatrician / Physician• IAP/IMA Representative• Representative of Director, Drug Control
  45. 45. Media hunts for sensational news Stick to basic messages when dealing with media
  46. 46. Media Management -AEFI• Verification of FIR / PIR• Guessing / speculation to be avoided• Attempt to cover up to be avoided• Designated responsible spokesperson (block / district / state) should talk to media• Provide a complete / simple account of events• Compassionate & caring attitude is needed• Avoid off-hand & disparaging remarks• Try to convince that despite AEFI, the benefit of vaccination outweighs the risks
