Information on the current situation, as of 24 September 2021
Switzerland and Liechtenstein
Cases despite full vaccination
Cases despite full vaccination are confirmed SARS-CoV-2 infections that have occurred after maximum immune protection has been built – in other words 14 days after the second dose of vaccine has been administered. Cases despite full vaccination are to be expected; this is because while the efficacy of the vaccine is very high, it is still below 100%.
We have been collecting data on immunisation status since the end of January 2021. These data are based on information sent to us by doctors and hospitals under their duty to notify.
We assume that the number of unrecorded cases among those fully vaccinated is higher than for those not vaccinated. This is due to the fact that vaccinated people often experience only mild symptoms and are therefore less likely to visit a doctor; or they get themselves tested at test centres or pharmacies because they do not need medical treatment. In the latter case, we receive a report on the laboratory findings, but no indication as to the person’s vaccination status.
If you are assessing cases despite full vaccination, please consider the proportion of fully vaccinated people (under the vaccination strategy older people are more likely to be vaccinated) and all cases in the same time period.
