Indiana State Department of Health

November 2009

GLOSSARYMulti dose Vial (MDV): 5mL vial contains at least 10 .5mL

doses of vaccinePrefilled Syringes (PFS): Syringes arrive prefilled with

vaccine for either .25mL or .5mL doseIntranasal: Nasal spray vaccineVaccine presentation: MDV, PFS or Intranasal

VACCINE STORAGE & HANDLING

3

WHY STORAGE & HANDLING IS IMPORTANT Vaccine that is not stored correctly becomes nonviable

and cannot be used Thousands of dollars in wasted vaccine

If nonviable vaccine is used, people believe they are vaccinated when they are actually not immune

4

UNDERSTANDING THE COLD CHAIN Begins with the manufacturer

Continues to the distributor Then to the provider Until the vaccine has been properly

administered to the patient Vital that proper storage has been

maintained through the entire link Process is then extended anytime

the vaccine is being transported to off-site clinics.

If vaccine transportation is necessary for an off site clinic, it is critical that vaccine potency is protected by maintaining the cold chain at all time.

5

PROPER STORAGE UNIT Household or commercial

–style refrigerator/freezer unit.

Refrigerator and freezer compartments must each have a separate external door.

6

REFRIGERATOR AND FREEZER POLICY Refrigeration/Freezer Standards For Vaccine Storage

Policy Number: II-02 (R3-2/2009) Refrigerators and freezers used for permanent storage of

publicly provided vaccines must meet the following minimum standards:

Have separate external doors, with separate gasket door seals for the refrigerator unit and the freezer unit.

Refrigerators must maintain a temperature range from 2°C - 8°C, (35° F - 46° F) year-round.

7

REFRIGERATOR AND FREEZER POLICY CONT. Refrigerators must be dedicated to the storage of

vaccines. Refrigerators must have enough room to store the largest

anticipated vaccine inventory, while maintaining proper air circulation.

8

DO NOT USE DORM-SIZE REFRIGERATORS

Dormitory type refrigerators have been shown to be unsuitable for the storage of vaccine and are not acceptable for use with CDC or ISDH except for the short term storage at a clinic site.

9

VACCINE SPECIFIC CONSIDERATIONS LAIV

Refrigerator storage Prefilled syringes

Once needle attached, must use same day All inactivated vaccines

Do not freeze or expose to freezing temperatures

10

VACCINE STORAGE AT THE OFF SITE LOCATION The cold chain must be maintained once vaccine has been transported to

the off site clinic. Ideally, vaccines should be transferred to and stored in a storage unit at

the off site location. If off site storage units are utilized, prior temperature monitoring is required to

ensure that the refrigerator and freezer compartments can maintain proper temperatures throughout the clinic day.

Separate thermometers will be necessary to monitor temperatures 2-3 days prior to the off site clinic.

If neither a full-size unit nor a dorm-style unit is available for use at the off site location, vaccines can be stored in portable refrigerators and/or in the Styrofoam™ containers used for transport. If vaccine must be maintained in an insulated cooler during an off site clinic,

keep the cooler closed as much as possible. Limit the opening/closing of the cooler by taking out 5 doses at a time. A thermometer must be kept in the cooler with the vaccines, and temperatures

should be checked and recorded periodically to ensure that the cold chain is not broken.

11

 MONITORING TEMPERATURES DURING OFF SITE CLINICS All vaccine storage units or containers must be monitored for

temperatures throughout the clinic day. The refrigerator compartment must maintain a temperature

range between 35° and 46°F (2° and 8°C). The temperature should never fall below 35° F (2° C) or rise above

46° F (8° C). It is best to set the temperature mid-range to achieve an average of

40° F (5° C). This temperature setting will provide the best safety margin.

At a minimum, vaccine temperatures should be checked and recorded hourly.

Assign a single staff person to monitor and record storage unit temperatures throughout the clinic day on an hourly basis.

12

INACTIVATED VACCINE (IV) OR LIVE ATTENUATED INFLUENZA VACCINE (LAIV)IV Inactivated vaccine “flu shot” IM administration Ages 6 months and older

LAIV Live vaccine FluMist Nasal administration Ages 2-49 years and

healthy and non pregnant.

13

Children age 9 and under must return for a second dose of either vaccine in 4 weeks. The time frame may be longer, but cannot be shorter than 4 weeks.

LIVE ATTENUATED INFLUENZA VACCINECONTRAINDICATIONS AND PRECAUTIONS These persons should receive only inactivated influenza

vaccine Immunosuppression from any cause Pregnant women Children younger than 2 years of age Persons 50 years of age or older Persons with chronic medical condition, including asthma Children and adolescents receiving long-term aspirin therapy Children younger than 5 years with recurrent wheezing

medical conditions

chronic health conditions

VACCINE ADMINISTRATION

18

SCREENING The key to preventing the majority of serious adverse

reactions is screening Every person who administers vaccines should screen

every patient for contraindications and precautions before giving the vaccine dose

Each local health department may have their own screening document

Any questions should be directed to the nurse or physician in charge of the clinic

19

TYPICAL SCREENING QUESTIONS Is your child or are you sick today? Allergies to food or medications? Any problems after previous flu shots? Problems with the immune system? Pregnant? Any shots or nasal mist in the last 4 weeks?

Each local health department will incorporate these and perhaps other questions into their own screening form

20

PREPARATION Keep vaccine refrigerated until time to reconstitute

and/or administer Inspect the vaccine vial Never use expired vaccine Label all vaccines that are drawn up No pre-filling syringes

21

INFECTION CONTROL Hand hygiene

Single, most effective disease prevention activity Hands should be washed thoroughly with soap and water or

cleansed with an alcohol based antiseptic Gloves are not mandatory unless:

During vaccine administration there is potential for exposure to blood/bodily fluids

Provider has open lesions on the hands May be facility mandated policy

22

INTRANASAL ADMINISTRATION LAIV is supplied in a

prefilled, single-use sprayer containing 0.2 mL of vaccine.

An attached dose-divider clip is removed from the sprayer after administration in one side to administer the second half of the dose into the other nostril.

Administer 0.1 ml per nostril If patient sneezes or has nasal

discharge, do not repeat dose.
