Vulnerable children aged 5-11 to get Pfizer's Covid jab

Vulnerable children aged 5-11 to get Pfizer’s Covid jab: JCVI recommends vaccine for 330,000 youngsters who are immunosuppressed or live with someone who is high risk

  • The MHRA approved a formulation of Pfizer’s Covid vaccine for over-fives 
  • Around 330,000 children aged between five and 11 will be offered the vaccine
  • Children will receive two jabs at a third of the adult dose, eight weeks apart 

Children as young as five years old will be offered the Pfizer vaccine in the UK, advisers announced today as part of Britain’s fight against the Omicron variant. 

The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) made the approval following a robust review of safety data that showed a specific formula of the company’s jab is more beneficial than harmful for those in the age group. 

And the Joint Committee for Vaccination and Immunisation (JCVI) is now advising that children aged five to 11 who are in a clinical risk group or who are a household contact of someone who is immunosuppressed should be offered two doses.

Around 330,000 children are included in the groups, JCVI Covid chair Professor Wei Shen Lim said at a press briefing this afternoon.

They will be given two 10-microgram doses of the age appropriate Pfizer formulation — a third of the adult dose, with eight weeks between the first and second doses.

Advisers are expected to issue more recommendations for extending the rollout to other five to 11-year-olds in due course after looking at additional data, as well as on the Omicron variant more broadly. 

Meanwhile, the JCVI also announced Britain’s booster programme is set to be extended to teenagers, with third doses set to be given to some over-12s. 

The JCVI has advised that booster vaccinations should be offered to around 500,000 teens aged 16 to 17 years, and children aged 12 to 15 who are in a clinical risk group or who are a household contact of someone who is immunosuppressed.

Children aged 12 to 15 years who are severely immunocompromised and who have had a third primary dose will also be offered a booster.

Most children only experience mild symptoms after being infected with Covid.

Just one in 300,000 children who test positive for Covid die, according to UK Government data.  

And the risk of being hospitalised and getting admitted to ICU is similarly low.

But the risk is higher to children with serious underlying conditions. 

The JCVI has yet to release its updated guidance on vaccinating children aged 11 and under.

But its latest advice on recommending first jabs to over-12s suggested one Pfizer dose only prevents 131 hospital admissions per million 12-15-year-olds.

And second doses only prevent nine hospital admissions for every million dished out to the age group. 

The figures are likely to be less for five- to eleven-year-old, who are less vulnerable to the virus. 


Myocarditis — an ultrarare form of heart inflammation — is the main side effect of the Pfizer vaccine that concerns experts. 

Data shows the risk is slightly higher in adolescents than adults, particularly in boys.

The JCVI has not released data on how many cases are expected in children aged five to 11 but studies show children in younger age groups are less at risk than teenagers.

It found myocarditis cases in between 2.6 to 17.7 million first vaccine doses in children aged 12 to 15.

And the condition was found in between 20.9 to 42.2 children in the age group per million second doses dished out.

Dr June Raine, MHRA chief executive, said: ‘Parents and carers can be reassured that no new vaccine for children would have been approved unless the expected standards of safety, quality and effectiveness have been met.

‘We have concluded that the Pfizer/BioNTech Covid-19 vaccine is safe and effective for five to 11-year olds, with no new safety concerns identified.

‘We have carefully considered all the available data and reached the decision that there is robust evidence to support a positive benefit-risk for children in this age group.

‘Our detailed review of all side-effect reports to date has found that the overwhelming majority relate to mild symptoms, such as a sore arm or a flu-like illness.

‘We have in place a comprehensive safety surveillance strategy for monitoring the safety of all UK-approved Covid-19 vaccines and this includes children aged 5 to 11 years old.’  

Boosters will be given to over-16s and some over -12 in the form of 30 micrograms of the Pfizer/BioNTech vaccine, given no sooner than three months after completion of the primary course.

Professor Lim said: ‘The majority of children aged five to 11 are at very low risk of serious illness due to Covid-19.

‘However, some five to 11 year olds have underlying health conditions that put them at higher risk, and we advise these children to be vaccinated in the first instance.

‘For children and young people who have completed a primary course of vaccination, a booster dose will provide added protection against the Omicron variant.’

More than 30million boosters have now been given in the UK, new figures show. 

A record 968,665 booster and third doses were reported for the UK on Tuesday. The previous record was 940,606 doses on Saturday. 

It means a total of 30.8million booster and third doses have now been delivered, with 6.1million in the past seven days. The figures have been published by the UK’s four health agencies. 

Around 58 per cent of all adults in the UK have now had a booster or third dose of Covid vaccine, up from 46 per cent a week ago. 

The decision to extend the rollout came after the world’s biggest study on myocarditis after the vaccine in children suggested there is not an increased risk of heart inflammation from the jab in British adults and older teenagers.

Analysis by the universities of Edinburgh and Oxford said myocarditis was occurring at a rate of three per million jabs administered in people aged 16 to 40.

They said this was not significantly different to the rate in the general population for the same age group. 

Reports of myocarditis in young people and teenagers in other countries early in the rollout complicated the debate on whether British children should be jabbed. Data from Israel and US — where the dosage gap is only three weeks — suggested the condition was more common. 

Experts believe Britain’s 12-week spacing has cut the risk of myocarditis and helped keep numbers low.

Scientists described the data as ‘reassuring’ to young people. But because the data did not look at young people specifically, questions on incidence in teenagers unanswered. 

Vaccinating young children still makes many scientists uneasy due to the tiny risk the virus poses to them. 

No10’s advisers were originally unconfident on approving them because the benefits did not clearly outweigh the risks, with youngsters unlikely to fall serious ill or die with the virus. 

Revealed: What are other countries doing about Covid vaccinations for children

The United States starting rolling out Pfizer’s vaccines for children aged 5 to 11 at the start of November.

A panel of outside experts met on November 2 to vote on how broadly the shot should be recommended in the age group by the US Centers for Disease Control and Prevention (CDC). 

The vaccine was authorized by the US Food and Drug Administration in the age group on November 29.

But with many parts of the world still awaiting doses for more vulnerable people, the World Health Organisation has urged countries and companies that control the global supply of the vaccines to prioritize supply to COVAX.
