Health chiefs are urging young adults to have their vaccinations as coronavirus cases are set to rise further.
Their appeal comes after it was confirmed earlier this week that final restrictions are set to be lifted on “Freedom Day” Monday.
But a vaccinator based at the King’s Lynn Corn Exchange said its walk-in clinic had been “very quiet” this week.
Gary Walker, a volunteer with St John’s Ambulance, said: “It’s very frustrating as we’ve got everything set up in the hall ready to go, but we’re not getting the footfall.
“This is a golden opportunity for anybody aged 18 and over to get their first jab, or their second if it’s eight weeks after the first.”
Mr Walker, of King’s Lynn, said people who don’t live in the area, such as visitors and holidaymakers, can also attend the walk-in clinics.
“My granddaughter from Northern Ireland was over and she had her vaccination here. Now she will be able to have her second one before she starts university in September,” he said.
“Just walk in a clinic and the staff will find you on the system. The staff are brilliant and really welcoming.”
Matthew Winn, chief executive at Cambridgeshire Community Services NHS Trust, which runs the large scale vaccination centres across Norfolk and Waveney, has praised Lynn’s “fantastic team” for their excellent progress in vaccinating 63 per cent of 18 to 24-year-olds with their first dose.
But his message was for those eligible to have their jabs to do so – there is no need to book.
“The walk-in clinics have been introduced to make it even easier for people to get vaccinated. Millions of people are now benefiting from protection from the virus but rates of infection are rising across the country,” he said.
And Dr Louise Smith, director of public health added: “Getting vaccinated is the best way to reduce the impact of coronavirus, keeping yourself and others safe from serious illness.
“If you’ve had your first vaccine, make sure to book your second as it provides a clear boost to its effectiveness.”
North West Norfolk MP James Wild has warned infection rates will rise as the country moves to step four of the government roadmap and young people can be affected by coronavirus and long Covid.
He said: “The best thing everyone can do is to get vaccinated to protect themselves and family and friends by reducing the ability of the virus to spread.
“There are plenty of walk-in clinics in Lynn at the Queen Elizabeth Hospital and the Corn Exchange and I encourage people to take up the offer of a jab which is safe.”
At the Corn Exchange, walk-in clinics are seven days a week, 9am to 3pm and on Tuesday evenings from 5.30pm to 7.30pm.
