Long Covid is less likely to affect vaccinated people than unvaccinated people, a new review of 15 studies by the UK Health Security Agency (UKHSA) has concluded.

UKHSA said the people who received two doses of Pfizer-BioNTech , AstraZeneca or Moderna vaccine, or one dose of the single-shot J&J vaccine, were around half as likely to develop symptoms of long Covid compared to the unvaccinated, Reuters reports.

“These studies add to the potential benefits of receiving a full course of the Covid-19 vaccination,” said Dr Mary Ramsay, head of immunisation at UKHSA.
