Boosters raise vaccine effectiveness against Omicron by 88%: UK studies

Although the Omicron variant of Covid has been shown to evade vaccines, two new studies led by the UK health agency showed that a third booster dose increases vaccines’ effectiveness by 88 per cent.

The studies, led by the UK Health Security Agency (UKHSA), found a substantial reduction in risk of hospitalisation for Omicron cases after three doses of vaccine compared to those who are unvaccinated.
