How many people in Jersey have had COVID-19 twice? Of those, how many were double vaccinated?


Has anyone in Jersey had COVID-19 more than twice? If yes, how many times have they had it and how many were double vaccinated?



As at 11 October 2021, 45 individuals have had two COVID-19 infections. This total only includes people who are considered to have had two independent COVID-19 infections that were reported as separate cases in official statistics. It excludes so-called "clearance" cases, where a positive test result is considered to be due to an existing infection that has already been reported. Note that the definition of “clearance” case has evolved over the course of the pandemic, with emerging scientific evidence and changes to policy. Currently, a positive test result is considered a new infection only if it is an individuals’ first positive test result, or if more than 90 days has passed since any previous positive test result.

Note that Jersey has recorded over 10,000 positive cases to date, and that the number of people infected more than once is small in that context (<1%).

Note that anyone who has tested positive outside of Jersey would not be considered within this analysis so it may represent an undercount of reinfections of Islanders.

With regards the vaccination status of positive cases: Following a review of systems, it has been concluded that the information, as requested, is not held in recorded form. To answer the request, the data would need to be extracted from various sources and manipulated. The Freedom of Information (Jersey) Law 2011 does not require a Scheduled Public Authority to manipulate data in order to provide a response. Article 3 of the Freedom of Information (Jersey) Law 2011 therefore applies.


As at 11 October 2021, there were no recorded occurrences of individuals having more than two separate COVID-19 infections.

Article applied

Article 16 - A scheduled public authority may refuse to supply information if cost excessive

(1) A scheduled public authority that has been requested to supply information may refuse to supply the information if it estimates that the cost of doing so would exceed an amount determined in the manner prescribed by Regulations [Freedom of Information (Costs) (Jersey) Regulations 2014].
