Older people are being urged to become fully vaccinated against Covid as a world-first study shows thousands of hospital admissions and deaths in the UK could have been avoided if everyone had had all of their doses.
The rollout began strongly in the UK, with 90% of the population over the age of 12 vaccinated with at least one dose by January 2022. However, rates of subsequent doses fell sharply, a study shows, with less than half the population fully jabbed by June 2022.
