    Health professionals are trusted sources of information and their recommendations for vaccination go a long way in motivating clients to get vaccinated. Based on age and risk factors, health professionals should consider which vaccines are required for an individual and a family. To obtain informed consent for vaccination, the individual should know about the disease that the vaccine will prevent and the side effects, benefits, and risks of vaccinating. The health professional should notify the patient before the vaccination visit and share materials about vaccine-preventable diseases (VPD) wherever possible. For example, expecting parents can start the conversation about a vaccination series for their infant in the pre-natal period.

    On the Day of Vaccination

    Begin the visit asking if the client has any questions about the vaccine. Use a presumptive statement, meaning assume the client is ready to vaccinate. This approach is recommended because it normalizes vaccines as an everyday occurrence that is recommended by the healthcare provider rather than an uncommon, fearful event. For example, “Today you will get your vaccine to protect against tetanus.” Clients may respond with hesitancy if they sense the health professional is unsure or not confident about immunization. The best way to convey confidence is by being a knowledgeable provider.

    See Table 3.1 about steps and considerations involved in the pre-vaccination checklist. For further information about effective communication strategies, visit Chapter 5 on Vaccine Hesitancy.

     

    Table 3.1: Pre-Immunization Checklist

    Steps Considerations

    Assess the client’s current health status.

     

    • Is the client pregnant?
    • Is the client immunocompromised or immunosuppressed? Does the client have any acute or chronic immunocompromising conditions including HIV?
    • Is there a (suspected) family history of congenital immunodeficiency disorder? (e.g., has the child had failure to thrive and recurrent serious infections?)
    • Has the client taken any immunosuppressants, including corticosteroids, in the past 3 months or during a current pregnancy?
    • Has the client received any blood transfusions or blood products in the last year?

    Discuss benefits and risks of receiving or not receiving the vaccine.

     

    • Has information been provided regarding administration of the vaccine?
    • Have all questions about benefits and risks been answered completely?

    Assess for contraindications and precautions.

     

    • Does the client have a history of anaphylactic reaction to vaccines or a component of a vaccine?
    • Does the client have severe asthma?
    • Does the client have congenital malformation of the GI tract or history of intussusception (for rotavirus vaccine)?
    • Has the client had Guillain-Barré syndrome with an onset within 6 weeks of immunization?
    • Is the client immunocompromised?
    • Is the client pregnant?
    • Does the client have active, untreated tuberculosis?

    Note: Health professionals need to inform themselves of contraindications for each vaccine respectively. Also assess for client’s health status including age, comorbid conditions, risk factors and travel plans .

    Evaluate reactions to previous vaccines.

     

    • Has the client ever had a serious reaction (anaphylactic reaction) after receiving a vaccine or is the client aware of any allergies to components of the vaccine (e.g., gelatin, neomycin, thimerosol) or to latex?

    Discuss frequently occurring minor adverse events and potential rare severe adverse events.

     

    • Have you talked to your client about what to do if they experience an adverse event?
    • Are you able to identify types of adverse events (e.g., injection site, systemic, allergic, neurological, and other reactions) that require reporting?
    • Have you familiarized yourself with the most likely timing of these events?

     

     

    Points of Consideration

    A common misconception among health professionals is that vaccination should be postponed in the event of minor or moderate acute illness such as upper respiratory tract infections, otitis media, and mild gastrointestinal illness, or in persons on antibiotic therapy. Generally, clients experiencing mild to moderate acute illness (even with fever) can be vaccinated. The health professional should use their clinical judgment to assess the risk, benefits, and health profile of the client when making a decision to delay vaccination.

    Informed Consent

    Health professionals should obtain consent from the client or the Substitute Decision Maker (SDM) prior to vaccinating. Consent must be informed, voluntary, related to the treatment being proposed, and not obtained through misrepresentation or fraud (College of Nurses of Ontario, 2017). Health professionals should consult their respective regulatory association for further information and guidelines on obtaining consent.

    Preparation

    Health professionals should ensure the client has met the criteria to vaccinate and screen for any contraindications, potential drug interactions, or precautions (see Chapter 4 on Vaccine Safety). Table 3.2 details criteria the health professional should actively verify prior to immunization. Remind the client that they will need to remain at the healthcare facility for a minimum of 15 minutes after receiving the vaccine in order for potential side effects to be monitored.

     

    Table 3.2: Health Professional Criteria Before Vaccine Administration

    Criteria Ask yourself

    The right client, informed consent, and contraindications

     

    • Have I confirmed the client’s name and date of birth (DOB)?
    • In the case of a substitute decision maker (SDM), have I learned their relationship to the client?
    • Is it appropriate for the SDM to provide consent?
    • Why am I giving this vaccine?
    • What is the client’s immunization history?
    • Have I ensured the client meets the criteria?
    • Have I verified contraindications, drug interactions, and precautions?
    • Have I asked about history of allergy and anaphylaxis?
