the "Heart" of the matter (pardon the pun) when it comes to young kids...
"The FDA advisory panel voted in favour of approval on 26 October, on the basis of clinical-trial data showing that the Pfizer–BioNTech vaccine is about 91% effective at preventing symptomatic SARS-CoV-2 infection in 5- to 11-year olds. Around 4,650 children participated in the trial; nearly two-thirds received vaccine doses that were one-third that of an adult jab (the others received a placebo). In a procedure similar to that used to vaccinate adults with the messenger RNA jab in the United States, kids received two doses, three weeks apart.
For the children tested, the data show that the vaccine is safe. mRNA-based vaccines have been linked to a very small risk of myocarditis, an inflammation of the heart muscle, and pericarditis, an inflammation of the lining around the heart, particularly in young men. BUT THERE WERE NO REPORTS OF EITHER CONDITION IN THE 5-TO 11 YEAR OLDS) involved in the trial, which is a very encouraging sign, says Andrew Pavia, chief of the division of paediatric infectious diseases at University of Utah Health in Salt Lake City. If the shot were distributed to a larger population, however, regulators would need to watch for any sign of the side effects, Pavia notes."
Also, your Lancet article clearly shows SOME ADVANTAGE for reducing transmissibility for vaccinated persons...and it supports vaccination especially for reducing hospitalizations and deaths...which IMO are the key metrics...do you disagree with that?
