Almost 100,000 adults across Swindon and the rest of the region have yet to be vaccinated against covid.
The figure was announced by Bath and North East Somerset, Swindon and Wiltshire Clinical Commissioning Group.
Health officials are urging those who remain unvaccinated to get the jab as quickly as possible, as doing so now will ensure more people are protected against coronavirus during the upcoming Christmas and New Year period.
Across the region, 92,527 adults eligible for the vaccine have yet to take up the offer, with Wiltshire’s unvaccinated total currently standing at 37,212.
Gill May, Director of Nursing and Quality, said: “History tells us that coronavirus case numbers go up when people mix more indoors, and with the party season about to begin, I would ask those who have so far refused the vaccine to think about how their decision could have adverse consequences for those around them this Christmas
“Remaining unvaccinated not only increases a person’s chances of catching coronavirus, but it also makes them more likely to pass it on to others, and I would hate for an innocent family celebration in late December to be the reason behind a serious hospital admission in early January.
“Covid-19 is still very much with us but, by having the vaccine, we can restrict its prevalence, limit its severity and, most importantly, protect ourselves and our loved ones from falling seriously ill.”
Vaccines, including first, second and booster doses, continue to be available at vaccination centres across the region, including Steam in Swindon.
Some community pharmacies also offer the vaccine, although larger venues usually have the best appointment availability, with new slots being added at each of the sites on a regular basis.
Since last December, more than 1.6m vaccines have been given out across Bath and North East Somerset, Swindon and Wiltshire.
This figure includes more than 755,000 first doses, around 703,000 second vaccinations and approximately 183,000 booster vaccines.
While some local vaccine sites are offering walk-in vaccinations, people are strongly advised to book an appointment using the National Booking Service, which is available online at www.nhs.uk or by calling 119.
