General Principles for Immunizations
Federal Requirements for Vaccinators
• Vaccine Information Statement (VIS)– Give a current, take-home copy of the relevant
VIS to the parent, legal representative, or adult recipient before each dose of each vaccine
– Use the VIS published by the CDC– Mandatory for vaccines covered under the VICP– Mandatory for vaccines purchased under federal
contract– Encouraged for all other vaccines
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Federal Requirements for Vaccinators
• Vaccine Information Statement (VIS)– Provide VIS for each component of combination
vaccines if there is no VIS for the combination– Use visual or oral supplements for illiterate or blind
patients– Translations are available
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Federal Requirements for Vaccinators• Permanent Medical Record or Office Log
– Name of the VIS, publication date, and date it was given to the recipient Patient signature is not required VIS should not be construed as informed consent, which
may be required in some states
– Name and title of individual who administered the vaccine
– Date of administration– Manufacturer– Lot number– Address where the permanent record is kept
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Federal Requirements for Vaccinators
• Report to VAERS– Any event listed by the manufacturer as a
contraindication to subsequent doses of the vaccine
– Any event listed in the Reportable Events Table that occurs within the specified time period after vaccination
• Adhere to the Occupational Safety and Health Administration Bloodborne Pathogens Standard
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #1
• Any vaccines can be given at the same time (using separate sites)
• Exception: VAR and smallpox vaccine• VAR PI warns against concomitant
administration with PPSV23 (impaired response to VAR)
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
VAR: varicella
Rules by Which to Vaccinate: #2
• Live vaccines not given at the same time should be separated by at least 4 weeks
• Exceptions– YFV may be given at any time after single-antigen
measles vaccine– Live oral vaccines (RV and Ty21a) may be given
at any time in relation to any other live vaccines– LAIV is not an exception
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
YFV: yellow fever vaccine; RV: rotavirus; Ty21a: typhoid 21a; LAIV: live-attenuated influenza vaccine
Rules by Which to Vaccinate: #3• Different inactivated vaccines may be given at
any time with respect to each other• Exception: The AAP recommends a minimum
interval of 1 month between Tdap and MCV4-D (formulation with diphtheria toxoid conjugate, Menactra) if not given on the same day– Concern that too many doses of diphtheria toxoid in
sequence can cause increased reactogenicity
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #4• There are minimum acceptable intervals between
doses of the same vaccine• Exceptions
– The 4-day grace period (not applicable to RAB)– Early, accelerated, or compressed schedules in certain
situations• Caveat
– A minimum interval is a minimum interval except when it’s not
– DTaP doses 3 and 4: 6 mo, but 4 is OK– VAR doses 1 and 2: 3 mo, but 28 days is OK
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.RAB: rabies vaccine
Rules by Which to Vaccinate: #5
• There are minimum ages for administration of all vaccines
• Exceptions– HepB– BCG– Rabies vaccine
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #6
• Partial or fractional doses of a vaccine should never be used
• Exception: None
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #7
• A multidose vaccine series should not be restarted if the recommended dosing interval is exceeded
• Exception: Oral typhoid Ty21a
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #8
• Similar vaccines made by different manufacturers are interchangeable
• Exception– Preference for using the same brand of DTaP,
HPV, and RV for the entire series– Vaccination should not be deferred if same brand
is not available
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #9• There is no harm in vaccinating a person who
has already had the disease or the vaccine• In fact, there is reason to vaccinate when
disease can be caused by multiple serotypes• Exceptions
– Too many doses of PPSV23 or tetanus or diphtheria toxoid-containing vaccines can cause increased reactogenicity
– Increased reactogenicity if anthrax vaccine given to person who has had anthrax
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Rules by Which to Vaccinate: #10
• Live vaccines should be deferred after receipt of antibody-containing blood products
• Exceptions– LAIV, Ty21a, RV, YFV, ZOS– MMR and VAR should not be deferred in
postpartum women who received antibody-containing blood products during pregnancy, including anti-Rho(D) globulin

Other Vaccination Pearls
• Indications for serology– Prevaccination
Adults without personal history of chickenpox Internationally adopted children (consider)
– Postvaccination HepB: high-risk health care workers and dialysis patients RAB: pre-exposure prophylaxis for laboratory workers Some cases of invalid dosing
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Other Vaccination Pearls• Physical examination not required for vaccination• Gloves not routinely needed• Not necessary to change needles after withdrawing
vaccine from vial• Rubber stopper should be swiped with alcohol• Aspirating back on the syringe not necessary• Injections in the same area should be separated by
≥ 1 inch• Syringes should not be prefilled by the end user
(exception: mass influenza immunization campaigns where only 1 vaccine type is being used)
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Contraindications
• Contraindications increase likelihood of a serious adverse event– When present, vaccine should not be given
• Permanent contraindications for all vaccines: severe allergy to vaccine or component
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Precautions• Might increase risk of a serious adverse
event• Could compromise immunogenicity• Could be mistaken for a vaccine reaction• Default position: defer vaccination
– Risk of deferral: susceptibility to disease– Risk of vaccination: largely theoretical
• Considerations: epidemiology of disease, patient’s circumstances, missed opportunities
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.
Notable Contraindications
• DTaP– Encephalopathy within 7 days of pertussis-
containing vaccine– Progressive neurological disorder (until stabilized)
• Allergic to components– Baker’s yeast: HepB, HPV– Rodent or neural proteins: JEV (JE-VAX)– Eggs: LAIV, IIV, YFV– Gelatin or neomycin: MMR, VAR
Marshall G. The Vaccine Handbook. PCI Books, Inc: 2010.

Notable Contraindications
• Pregnancy: LAIV, MMR, smallpox, VAR, ZOS• Immune impairment
– Any: smallpox, Ty21a, YFV– Severe: LAIV, MMR, VAR, ZOS
• Aspirin or salicylate therapy: LAIV• Untreated active TB: MMR, VAR, ZOS
Vaccine Screening Questions• Is the child sick today?• Does the patient have allergies to medicines, food, a
vaccine component, or latex?• Has the patient had serious reactions to previous
vaccinations?• Has the child had a health problem with lung, heart,
kidney or metabolic disease (eg, diabetes), asthma, or a blood disorder? Is he/she on long-term aspirin therapy?
• If the child is between 2 and 4 years, has a health care provider told you that the child had wheezing or asthma in the past 12 months?

Vaccine Screening Questions• Has the child, a sibling, or parent had a seizure; has the
child had brain or other nervous system problems?• Does the child have cancer, leukemia, AIDS, or another
immune system problem?• Has the child taken cortisone, prednisone, other
steroids, anticancer drugs, or had radiation treatments in the past 3 months?
• Has the child received a blood or blood product transfusion, been given immune globulin or an antiviral drug in the last year?

Vaccine RecommendationLAIV Contraindicated if profoundly
immunosuppressedMMR May be usedRV May be usedSmallpox ContraindicatedTy21a May be usedVAR May be used (avoid contact if lesions develop)YFV May be usedZOS May be used (standard precautions is lesions
