Covid-19: Should all children get a vaccine?

Vaccinating children is routine and widely accepted - measles, mumps, polio, diphtheria, rotavirus, multiple strains of meningitis, whooping cough… the list goes on. All this starts from just a few weeks old. So, what about Covid-19? Some countries are cracking on. The US is immunising children between 12 and 15. It expects to have enough safety data to go even younger next year. But in the UK - the BBC has been told - a decision to vaccinate all 12 to 17-year-olds is unlikely to be recommended by UK experts any time soon. There is a scientific question - will vaccinating children save lives? - which is complex as the answer may vary from country to country.
