New XEC Covid Variant: What You Need to Know as It Begins to Spread

A new Covid-19 variant, known as XEC, has begun to spread and could soon become the dominant strain, according to scientists. First identified in Germany in June, cases of this variant have now been reported in the UK, US, Denmark, and several other countries, as shared by users on X (formerly Twitter).

XEC carries some new mutations that may increase its ability to spread during the autumn. However, experts emphasize that vaccines should still help prevent severe illness. For those more vulnerable to serious Covid-19 complications, the NHS continues to offer free booster shots.

Vaccines Still Provide Strong Protection

Although current vaccines have been updated to better match recent Covid variants, they do not specifically target the XEC variant, which evolved from earlier Omicron subvariants. Prof Francois Balloux, Director of the Genetics Institute at University College London, told the BBC that while XEC may have a "slight transmission advantage" over other variants, existing vaccines should still offer robust protection.

He also noted that XEC might become the dominant subvariant over the winter months.

XEC’s Spread Still in Early Stages

Eric Topol, Director of the Scripps Research Translational Institute in California, explained that XEC is "just getting started" and it will likely take weeks or even months before it gains significant traction. Speaking to the LA Times, he said, "XEC is definitely taking charge, and it looks like it will be the next variant to watch, but it's still months away from reaching high levels."

Symptoms of the XEC Variant

The symptoms of XEC appear to be similar to those of previous Covid variants, resembling cold or flu-like signs, such as:

• High fever
• Body aches
• Fatigue
• Cough or sore throat

Most people recover from Covid-19 within a few weeks, although some may take longer to feel fully well.

XEC Variant Growth in Europe

Covid data analyst Mike Honey has reported "strong growth" of the XEC variant in Denmark and Germany. However, with reduced routine testing, it is becoming harder to accurately gauge how widespread Covid-19 cases are.

The UK Health Security Agency (UKHSA) reassures the public that it is normal for viruses to mutate over time. The agency continues to monitor emerging variants closely, both in the UK and internationally, and regularly publishes updated data.

Who Qualifies for a Free Booster Vaccine?

The NHS is offering free booster vaccines to the following groups:

• Adults aged 65 and over
• Residents of care homes for older adults
• People aged six months and older who are in a clinical risk group
• Some frontline NHS, care home, and social care workers

The main vaccination campaign for flu and Covid-19 is set to begin in October, though some may receive their vaccines earlier.

Dr. Gayatri Amirthalingam, Deputy Director of UKHSA, stated, "It is expected for viruses to change genetically over time. UKHSA continues to closely monitor all available information regarding emerging Covid variants both in the UK and globally, and we regularly share our findings. Vaccination remains the best protection against severe illness, and we urge those contacted by the NHS to come forward for their autumn vaccination."
