Current immunization level against infection with Omicron-variant at just under 80%

As of early March, we have updated our (dwh GmbH, TU Wien, DEXHELPP) model-based estimate of immunization levels in Austria underwent its monthly update.

As of March 1, 2022, approximately 90% of the Austrian population was immune to infection with the delta variant and approximately 77% was immune to infection with the omicron variant, specifically, subtype BA.1. This value has also increased by about 11% over the last month due to the high number of cases. Conversely, the protection against infection due to third vaccinations from late fall 2021 is now also decreasing again (due to the time lag and decline in efficacy).

Overall, the calculations show that …

  • the peak of the BA.1 wave is already exceeded and
  • that of BA.2 is likely to be imminent (see title chart).
  • Current measure relaxations may contribute to delaying the drop. See: Civil servants return from home office (ORF).

Notes

The underlying assumptions of this model-based estimate can be found in this chart. They differ slightly from the assumptions in the recently published estimation of immunity progression, leading to differences in the calculated immunity levels accordingly.

While these differences are minor, we are currently working on updating and standardizing the assumptions and will follow up with an update in the coming days.
