People who have had the Omicron variant do not appear to have protection from catching the Covid strain again, a new study has found.
Imperial College London scientists have found that while with the original Covid virus and other subsequent variants, people have had some level of immunity to catching the it again, they have not seen this with their research on Omicron.
The findings could explain why people who have had Omicron have then caught the variant again quickly afterwards.
