Young people queued around the block for a vaccine after an offer was made for people to book themselves in for a jab.
People under the age of 30 were given the chance to book in for a jab at Venue Cymru in Llandudno on Tuesday, with many appearing to take up the opportunity.
Dozens were seen queuing outside the facility during the evening.
On Tuesday afternoon, Betsi Cadwaladr University Health Board said people aged 18 to 30 could book appointments online before heading to the centre for a first jab through the evening.
And young people living in Gwynedd will also soon have a chance to get a jab by booking.
The health board said: “People aged between 18 – 29 who live in the Dwyfor and Meirionnydd areas of Gwynedd are invited to book their appointment for their first vaccination.
“Clinics administering the Pfizer vaccine will be held at Ysbyty Alltwen and in Dolgellau to vaccinate this younger age group during May.”
They said the Ysbyty Alltwen dates would be the 14th, 15th and 16th of May, while jabs would be given in Dolgellau on May 21.
To book an appointment call 03000 841 011 or 03000 841 012.
Vaccines for younger people
It comes after it was confirmed that some teenagers and people in their 20s will be getting their Covid-19 jabs ahead of some older people in North Wales.
The change in policy was the result of advice recommending that under-30s are offered an alternative coronavirus vaccine to the AstraZeneca jab.
Vaccination invitations are now being issued on the basis of vaccine availability and not merely according to age, the health board said.
In an update issued on Tuesday, the health board said that 409,956 people have now had a first dose of the vaccine, with 190,112 having had a second dose.
Of those groups mainly waiting for jabs now, 29% of 18 to 29 year olds have had a first jab, with 15% of 30 to 39 year olds and 43% of 40 to 49 year olds.
The health board also warned that they were seeing “a growing problem” with people failing to attend vaccination appointments.

They said: “Vaccines are never thrown away, but each missed appointment wastes vital NHS resources and creates significant logistical challenges for our staff, who are pulled away from other duties to contact people next in line at short notice to fill appointment slots.
“While a small number of these missed appointments are a result of duplicate appointments, incorrect contact details or appointment letters arriving late, we know that in the vast majority of cases, it is because people have failed to notify us that they cannot attend, or do not wish to be vaccinated.”
