The adverse event may be any unfavourable or unintended sign, abnormal laboratory finding, symptom or disease.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is reporting an AEFI important?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Provincial reporting of an AEFI is an important component of the overall safety assessment of any vaccine.&nbsp;Individual case reports of AEFIs represent an important source of data as they have the potential to generate signals of adverse reactions not previously recognized in clinical studies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Am I required to report AEFI?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, you&nbsp;are required to report AEFI to your&nbsp;local Medical Officer of Health under Section 38&nbsp;of the <em>Health Protection and Promotion Act<\/em> (HPPA) and its accompanying regulation, O.Reg 569 s.7.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What types of AEFI should be reported?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Under the HPPA, Section 38 the following events are considered reportable:<\/p>\n\n\n\n<ul class=\"wp-block-list mht-list\">\n<li>persistent crying or screaming, anaphylaxis or anaphylactic shock occurring within forty-eight hours after the administration of an immunizing agent,<\/li>\n\n\n\n<li>shock-like collapse, high fever or convulsions occurring within three days after the administration of an immunizing agent,<\/li>\n\n\n\n<li>arthritis occurring within forty-two days after the administration of an immunizing agent,<\/li>\n\n\n\n<li>generalized urticaria, residual seizure disorder, encephalopathy, encephalitis or any other significant occurrence occurring within fifteen days after the administration of an immunizing agent, or<\/li>\n\n\n\n<li>death occurring at any time and following upon an&nbsp;aforementioned symptom<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In general, any adverse event following immunization may be reported to your local Public Health for further follow-up and investigation if:<\/p>\n\n\n\n<ul class=\"wp-block-list mht-list\">\n<li>It has a temporal association with immunization (i.e. the event follows immunization); and<\/li>\n\n\n\n<li>Has no other clear cause at the time of reporting.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A causal relationship does not need to be proven, and submitting a report does not imply causality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If there is any doubt as to whether or not an event should be reported, a conservative approach should be taken and the event should be reported.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens to the information provided on the Ontario AEFI Reporting Form?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once a reported AEFI is received by the local health unit, it is reviewed and investigated. The local Medical Officer of Health (MOH) may make recommendations to the vaccine recipient\/caregiver with respect to additional follow-up and receipt of further doses of vaccine. Public Health Sudbury &amp; Districts enters AEFI reports into the integrated Public Health Information System (iPHIS), the electronic reporting system for reportable diseases and AEFI in Ontario.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.publichealthontario.ca\/en\/health-topics\/immunization\/vaccine-safety\">Public Health Ontario<\/a>&nbsp;(PHO) continuously monitors all AEFI reported via iPHIS and transmits to PHAC for inclusion in the Canadian Adverse Events Following Immunization Surveillance System (CAEFISS), a national database containing AEFIs reported from all provinces and territories in Canada.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is an adverse event following immunization (AEFI)?
