any untoward medical occurence which follows administration of an active immunizing agent which does not necessarily have a causal relationship with the use of a vaccine

which types of AEFI should be reported

unexpected or unusual events

events requiring urgent medical attention

complete AEFI form

• include as many details as possible (info ab the immunizing agent, details of ae, impact and level of care obtained as a result, outcome of ae at the time the report is made)

send form to local health unit in your province/terittory

• in NL: Population Health Branch, Disease Control Division

process for introducing publicly funded vaccines

1. vaccine recommendation

2. review by provinical advisory committee

3. negotiation and funding

4. implementation and delivery

5. monitoring and evaluation

status of immunization registries in NL

electronic health record (HEALTHeNL)- only stores immunization info from 2003 onward, other injections like vit b12 etc not recorded

those in NL who received immunizations before 2003 can request a copy thru their regional health authority

whats the point of immunization schedules

aim to optimize the immune repsonse, while also taking into consideration different factors that can affect vaccine safety and efficacy

ex: age, underlying health conditions, previous vaccine history, potential interactions with other vaccines or meds

beneficence

act in the best interest of your patients and promote their well being

non maleficence

first do no harm

justice

emphasizes a fair, equitable and appropriate treatment of patients

autonomy

an individuals right to make their own decisions and choices, based on their personal values and beliefd

communication methods to provide info regarding immunizations

embrace a recipient centered approach

respect differences of opinion

present benefits and risks fairly and equally

clearly communicate knowledge using an evidence based approach

5C’s model of vaccine hesitancy

confidence

complacency

convenience

calculation

collective responsibility

3 factors influencing perspective on immunizations

contextual influences: arise from historic, sociocultural, environmental, health system/institutional, economic, or political factors

ex: media, messaging from leaders, religion/culture, socio economic influences, political or policy influences

individual/group influences: arise from personal perception of vaccines or from the social/peer environment

ex: personal or family/community member experiences with vaccination, beliefs or attitudes, knowledge and awareness, perceived risk vs benefit

vaccination influences: specific issues that are related directly to vaccination

ex: introduction of a new vaccine or new info for an existing vaccine, mode of administration, method of delivery, reliabiltiy/source of vaccine, vaccine schedule, costs.

strategies for addressing vaccine hesitancy

recognize the role HCPs play in the decision making process

build trust

start early

use a presumptive statement

use motivational interviewing techniques

keep messages short and simple

address pain head on

focus on protection of the individual and community

remind parents that community immunity does not guarentee personal protection

use visual aids
