The main argument in favour of vaccinating children is in order to prevent them keeping the virus in circulation long enough for it to transmit back to adults.
Experts fear that unvaccinated children returning to classrooms in September could lead to a boom in cases among people in the age group, just as immunity from jabs dished out to older generations earlier in the year begins to wane.
This could trigger another wave of the virus if left unchecked, with infection levels triggering more hospitalisations and deaths than seen during the summer.
Avoiding long Covid in children
While the risk of serious infection from Covid remains low in most children, scientists are still unsure of the long-term effects the virus may have on them.
Concerns have been raised in particular about the incidence of long Covid — the little understood condition when symptoms persist for many more weeks than normal — in youngsters.
A study released last night by King’s College London showed fewer than two per cent of children who develop Covid symptoms continue to suffer with them for more than eight weeks.
Just 25 of the 1,734 children studied — 0.01 per cent — suffered symptoms for longer than a year.
Extremely rare incidences of a rare heart condition have been linked to the Pfizer vaccine in youngsters.
Data from the Centers for Disease Control and Protection (CDC) in the US — where 9million 12- to 17-year-olds have already been vaccinated — shows there is around a one in 14,500 to 18,000 chance of boys in the age group developing myocarditis after having their second vaccine dose.
This is vanishingly small. For comparison, the chance of finding a four-leaf clover is one in 10,000, and the chance of a woman having triplets is one in 4,478.
The risk is higher than in 18- to 24-year-olds (one in 18,000 to 22,000), 25- to 29-year-olds (one in 56,000 to 67,000) and people aged 30 and above (one in 250,000 to 333,000). But, again, this is very low.
Britain’s drug regulator the MHRA lists the rare heart condition as a very rare side-effect of the Pfizer and Moderna vaccines.
They said: ‘There have been very rare reports of myocarditis and pericarditis (the medical term for the condition) occurring after vaccination. These are typically mild cases and individuals tend to recover within a short time following standard treatment and rest.’
More than four times as many hospitalisations were prevented as there were cases of myocarditis caused by the vaccine in 12- to 17-year-olds, the health body’s data show.
Jabs should be given to other countries
Experts have also claimed it would be better to donate jabs intended for teenagers in the UK to other countries where huge swathes of the vulnerable population remain unvaccinated.
Not only would this be a moral move but it is in the UK’s own interest because the virus will remain a threat to Britain as long as it is rampant anywhere in the world.
Most countries across the globe are lagging significantly behind the UK in terms of their vaccine rollout, with countries in Africa, Southeast Asia and South America remaining particularly vulnerable.
Jabs could be better used vaccinating older people in those countries, and thus preventing the virus from continuing to circulate globally and mutate further, than the marginal gains to transmission Britain would see if children are vaccinated, experts argue.
Professor David Livermore, from the University of East Anglia, has said: ‘Limited vaccine supplies would be far better used in countries and regions with large vulnerable elderly populations who presently remain unvaccinated — Australia, much of South East Asia and Latin America, as well as Africa.’
