How about that some vaccines may be more dangerous for ypung people than not having it?
If that is the case they wouldn't be approved for use by the relevant regulatory body.
For approval to be given for use the benefits of the vaccine must outweigh any risks.
So from the Dr June Raine, MHRA Chief Executive:
'We have carefully reviewed clinical trial data in children aged 12 to 15 years and have concluded that the Pfizer/BioNTech COVID-19 vaccine is safe and effective in this age group
and that the benefits of this vaccine outweigh any risk.'
And Professor Sir Munir Pirmohamed, Chair of the Commission on Human Medicines:
"We have been very careful to take into consideration the younger age group and the benefits of this population being vaccinated against any potential risk of side effects. There has been a thorough assessment and review of this data which was also looked at specifically by the CHM’s Paediatric Medicines Expert Advisory Group who are scientific experts within this age group, as well as the CHM’s COVID-19 Vaccines Benefit Risk Expert Working Group.
We have concluded that based on the data we have seen on the quality, effectiveness and safety of the vaccine,
its benefits do outweigh any risk."
