New Corona variant LP.8.1: What does this mean for us in Austria?

New Corona variant LP.8.1: What does this mean for us in Austria?

In recent weeks, the new Corona variant LP.8.1, a descendant of Omicron, has gained importance in Asia and Europe. Five years after the start of the pandemic, the variant, which has been dominant in countries such as the US, UK and Europe since April 2025, is being closely monitored. According to Kosmo, the study of wastewater in Austria shows that LP.8.1 has been dominant since April 2025, with the first detection in wastewater as early as July 2024.

The World Health Organization (WHO) has classified LP.8.1 as a “Variant Under Monitoring”, with global prevalences increasing but the public health risk assessed as low. According to WHO, recommended COVID-19 vaccines are suspected to continue to be effective against this variant, both symptomatic and severe disease.

Immune deviation and vaccine adaptations

One of the major concerns about LP.8.1 is its ability to evade immune defenses. In this context, Kosmo reports a strong humoral immune escape that can affect the antibody response caused by vaccinations or past infections. The mutations in the variant's spike protein promote this immune deviation and ensure that the virus multiplies more quickly.

The European Medicines Agency (EMA) has already recommended that vaccines be adjusted for the coming season to ensure better protection for risk groups such as the elderly and those with weakened immune systems. Initial studies suggest that the new mutations of LP.8.1 could affect the effectiveness of previous vaccines, underscoring the need for timely vaccine adjustments.

Current developments and symptoms

MedUni Vienna virologist Monika Redlberger-Fritz states that there is currently no epidemic development in Austria, but only sporadic cases. However, there is an increase in COVID cases in countries such as Singapore, Hong Kong, China and Thailand, with the majority of cases being mild. The symptoms of the new variant are not significantly different from other omicron subvariants, making identification difficult.

In conclusion, despite its increased global prevalence and potential for immune aberration, LP.8.1 is currently considered to be less threatening. However, it is recommended that you continue to monitor developments closely in order to be able to react adequately to possible changes.
