Nowhere does it say they don’t recommend it. Just that they aren’t going to universally mandate it.
“For otherwise healthy 12 to 15 year old children, their risk of severe COVID-19 disease is small and therefore the potential for benefit from COVID-19 vaccination is also small. The JCVI’s view is that overall, the health benefits from COVID-19 vaccination to healthy children aged 12 to 15 years are marginally greater than the potential harms.
Taking a precautionary approach, this margin of benefit is considered too small to support universal COVID-19 vaccination for this age group at this time. The committee will continue to review safety data as they emerge.”
Look, i don't care about back-and forth arguments, it 's better that i had listed the relevant evidence, and people can make up their minds on case-by-case, because it is possible that blind recommendations for vaccinations may end up being harmful. The phrase "universal vaccination" doesnt mean mandatory, it means that the benefit is so small that they don't recommend it to everyone, but only to kids in higher risk. The evidence seems to agree with them, despite governments' push for more vaccinations for their own reasons, which might be ineffective in the end. (There are countries that are pushing hard to vaccinate schoolchildren)
They recommend it, they don’t mandate it.
