A new Covid variant, XEC, is starting to circulate and could potentially become the dominant strain, according to scientists. First identified in Germany in June, cases of the XEC variant have since been reported in the UK, US, Denmark, and other countries, according to posts on X (formerly known as Twitter).
Potential for Spread
The XEC variant contains new mutations that may facilitate its spread during the autumn months, although experts assure that vaccines should still help prevent severe illness. The NHS continues to offer free booster vaccines to those at higher risk of serious Covid complications.
Updated Vaccines and Protection
Although scientists designed the latest vaccines to target more recent variants, they don’t specifically address XEC, which has developed from earlier Omicron subvariants. However, Prof. Francois Balloux, Director of the Genetics Institute at University College London, noted that while XEC has a ‘slight transmission advantage’ over other recent variants, experts expect vaccines to provide solid protection. He suggested that XEC could become the dominant strain by winter.
Growth in Global Cases
Eric Topol, Director of the Scripps Research Translational Institute in California, mentioned that XEC is in its early stages of spreading. According to him, it may take weeks or months before the variant causes a significant wave of cases. Mike Honey, a Covid data analyst, observed rapid growth of XEC cases in Denmark and Germany, though limited routine testing makes it difficult to gauge the overall spread.

Symptoms of XEC Covid
Symptoms of the XEC variant resemble those of cold or flu, including high fever, aches, fatigue, coughing, or sore throat. While most people recover within a few weeks, some may take longer.
Who Qualifies for the Covid Booster Vaccine?
The UK Health Security Agency (UKHSA) emphasizes that virus mutations are expected and continues to monitor emerging variants. Those eligible for a free booster vaccine include:
- Adults aged 65 and over
- Residents of care homes for older adults
- People aged six months and older in clinical risk groups
- Some frontline NHS, care-home, and social-care workers
The main vaccination campaign for flu and Covid will start in October, though some may receive their shots earlier. Dr. Gayatri Amirthalingam, UKHSA Deputy Director, reminded the public that vaccination remains the best defense against serious illness, urging those contacted by the NHS to come forward for their autumn vaccine.
