The majority of people eligible for a booster vaccination will be offered it by the end of the year, the Wales health minister has said.

In an updated Covid-19 vaccination strategy, published this week all 12-15 year olds will have been offered a first dose of the vaccine by November 1.

People who are severely immuno-suppressed will be offered a third dose of vaccine to provide them with as much protection as possible.

They will be prioritised for an urgent appointment at a time that’s right for them based on their treatment and the advice of their clinician.

The strategy also confirms that by November 1, offers will be made for a booster vaccination for care home residents and health and care staff.

Everyone in the Joint Committee on Vaccination and Immunisation (JCVI)’s 1-9 priority groups will be invited for a booster vaccination when it has been at least six months since their last dose.

As before, invitation letters will be sent directly from health boards and people are requested not to contact their GP.

Health minister Eluned Morgan has urged everyone eligible for booster vaccinations and flu jabs to take up the offer when it is made.

Ms Morgan said: “This winter will be incredibly difficult for our health service so it is vitally important for people to take up the offer of their Covid-19 and Flu vaccine if eligible to protect themselves and the NHS.

“Vaccinations for coronavirus are highly effective and protection against hospitalisation is estimated at around 95 per cent after the second dose.

"The flu vaccine will also protect people from serious complications and I encourage anyone who is eligible to get their flu vaccine regardless of their eligibility for a Covid-19 booster vaccine.

“We have so far given more than 4.6 million Covid-19 vaccinations and 85 per cent of the over 16 population are fully vaccinated.

“There is no concern over the supply of any of the vaccines and we hope as many people as possible take up the offers to continue to protect those most vulnerable and the NHS.”

Health boards have begun administering the booster, vaccinating 16 and 17 year olds and 12-15 year olds, including those most of risk due to underlying health conditions.

The Welsh Government said it is also encouraging 12-15 year olds to have a conversation about having the vaccine with their family or trusted adult.

Most younger adults will only have received their second Covid-19 vaccine dose in late summer or early autumn and they will still have a high level of protection.

The benefits of booster vaccination in this group will be considered when more information becomes available.

The strategy also sets out that a digital booking system is being developed to allow people to book appointments online to try to make it as easy of possible for people to come forward at a time which suits them.

Appointments for first doses of Covid-19 vaccines are still available for anyone unvaccinated.
