Description of intervention(s) / exposure
Myocarditis and pericarditis have been recognised by Medsafe and international regulators as a rare side effect of vaccination with mRNA COVID-19 vaccines, such as the Pfizer vaccine (Comirnaty). More information is needed to understand the long-term outcomes (>3 months) in people who experience myocarditis and/or pericarditis following vaccination with the Pfizer vaccine.
The study will be delivered as a survey to consumers and their healthcare provider.
1) The consumer survey will collect data on participant demographics, diagnosis, health and functional status, medicines, and medical history.
2) The healthcare provider survey will include questions on diagnosis and aetiology, tests and investigations, clinical management, and medical history.
The consumer survey will be a one-off survey of approximately 30 minutes, these will be delivered primarily through phone interviews conducted by experienced nurse interviewers through a health survey company. The option of face to face interviews will also be available (COVID-19 restrictions permitting) if the participant prefers. Participants will be given the opportunity to provide the name and contact details for their healthcare provider (General Practitioner/Nurse Practitioner or Practice Nurse and/or specialist) and to consent for us to contact them for the purposes of a survey. The healthcare provider survey will be predominantly online, however the option for this to be done by other mechanism will also be available.
Participants should have received a diagnosis of myocarditis and/or pericarditis any dose of their Pfizer COVID-19 vaccine between 20 February 2021 and 28 February 2022. People will be contacted to participate between March 2022 and July 2022.

Statistical methods / analysis
A descriptive analysis of quantitative survey data will be performed. A narrative summary of any additional information collected during the survey may be conducted. Data linkage will be performed with other relevant health data and data collected from surveys.
Outcomes will be analysed separately based on diagnosis (myocarditis and/or pericarditis). Subgrouping may also be performed based on the CDC criteria (met/not met) and/or Brighton Criteria (level 1-3/level 4-5), age, and gender, if sufficient information is collected. Sensitivity analysis may be conducted based on time to onset of symptoms/diagnosis (< or > 30 days). Most cases of myocarditis and/or pericarditis after vaccination occur within the first 7 days.
Cases where an alternative aetiology (other than the COVID-19 vaccine) was confirmed or highly suspected will be excluded from the analysis.

Summary
Brief summary
Myocarditis and pericarditis have been recognised by Medsafe and international regulators as a rare side effect of vaccination with mRNA COVID-19 vaccines, such as the Pfizer vaccine (Comirnaty). More information is needed to understand the long-term outcomes in people who experience myocarditis and/or pericarditis following vaccination with the Pfizer vaccine. To address this gap in important knowledge, a survey of consumers who are reported to have experienced myocarditis and/or pericarditis after Pfizer vaccination and their healthcare providers will be undertaken. Information gained through this survey will help us to better understand the safety profile of the Pfizer vaccine, and to inform future recommendations on the use of this vaccine in New Zealand. This project will be conducted by Medsafe, in collaboration with the National Immunisation Programme, and CARM, part of the NZPhvC based at the University of Otago. This study will be an extension of normal pharmacovigilance activities.
