The roll-out of Covid jabs for vulnerable five to 11-year-olds is set to start within days.
NHS England confirmed the vaccine roll-out would start by the end of the month, Monday, but it remains unclear which particular day.
An NHS spokesperson told The Mirror: "The NHS is on course to roll out paediatric doses of the vaccine to children aged five to 11 who are either at risk or household contacts of immunosuppressed contacts this month, as set out in a system letter that was issued 24 hours after the JCVI published guidance for this group."
Parents had voiced frustration, including one whose son has been unable to attend school classes for two years.
Justine, whose 11-year-old son has Down Syndrome, told the i newspaper : "I feel resigned to not knowing what is going on.
"I had to fight for my daughter to get her vaccine, she was one of the first 12 to 16-year-olds.
"Now I feel like there’s nothing that I can do. I know the vials are in the UK, and some have had it, but why aren’t they all being done together?”
In December The Mirror reported that children aged under 12 should only have the Covid vaccine if they're vulnerable or live with someone who is, but the official rollout has not yet begun.
The Joint Committee on Vaccination and Immunisation (JCVI) decided against recommending that all five to 11-year-olds be offered the Covid vaccine, at this stage.
It has been said more guidance will be issued in due course for this age group once further data is available and more is known about the threat the Omicron variant poses.
The organisation said some 330,000 younger children could be offered the vaccine.
However, children aged 5 to 11, who are in a clinical risk group or who are a household contact of someone of any age, who is immunosuppressed, should be offered a primary course of vaccination.
This will be two jabs of the 10-microgram doses of the Pfizer-BioNTech vaccine and will be given eight weeks apart.
