A new Covid variant, XEC, has been identified and is starting to spread across several countries, including the UK, US, and Denmark, after it was first detected in Germany in June. Experts believe the variant has some mutations that may enhance its ability to spread, especially during the autumn months. Despite this, vaccines are still expected to provide protection against severe illness, according to scientists.

Health officials from the University College London, have noted that XEC may gain traction over the winter due to its slight transmission advantage. However, the vaccines, which have been updated to tackle recent variants, should remain effective in preventing serious cases. Eric Topol, from the Scripps Research Translational Institute, believes it may take a few months before XEC becomes widespread.

The symptoms associated with XEC are similar to previous strains, including fever, aches, fatigue, and a cough or sore throat. While most people recover within a few weeks, the new variant's potential impact is still being monitored.

In preparation for the colder months, the NHS is offering free Covid booster shots to vulnerable groups, including the elderly, those in clinical risk categories, and some healthcare workers. Health authorities continue to monitor the situation and encourage eligible individuals to get vaccinated.
