The flu vaccine for children

Child in pyjamas cuddling teddy bear

If your child is aged between 2 and 16 years, the NHS will offer them the nasal spray flu vaccine in autumn or winter.

 

Before deciding whether or not to give consent, parents and guardians might want to explore safety, efficacy, ethics and necessity. 


Giving a flu vaccine to all children, every year, is a recent development – what are the health implications? Does the flu vaccine work well – does it really protect the child and those around them? What are the associated risks? And is it ethical to vaccinate children with the goal of protecting adults? 


Finally, is it necessary? Should we be concerned about the creeping normalisation of medicating our children rather than supporting their natural immune systems? 


If you want to do more research, the information below is a great starting point.

For otherwise healthy individuals, influenza is an unpleasant but usually self-limiting disease with recovery usually within 2 to 7 days.

In my view, this is unnecessary for healthy children who are at very low risk from flu. The evidence suggests that while proven influenza cases are reduced, they are simply replaced by other flu-like illnesses.

Further reading

Doc Malik has written a lengthy deep-dive into the children’s flu vaccine, available here. He has also produced an accompanying podcast episode. 


Among other things, he notes: 

  • The vaccine is described as being free, but it is actually paid for with our taxes. 
  • The NHS doesn’t offer parents clear information about exactly how risky (or not risky) flu is for their child – despite government data being available. 
  • Giving a child a vaccine to protect others is ethically questionable. 
  • The three virus strains inside Fluenz are not fixed, they are swapped out every single year. This has implications for safety studies, both complete and ongoing, as the product is not the same each year. 
  • Parents of asthmatic children should be particularly cautious about the vaccine. 


Doc Malik states: 


‘...when the government and health authorities talk about flu causing “complications” and “hospitalisation,” what they are actually describing, in their own data, is a risk to your child of just over one in 100,000 per year, and roughly half of even that small risk sits in children too young to be eligible for the nasal vaccine at all.’

You might want to talk to your doctor or health provider about the flu vaccine, before deciding whether to go ahead. Read more about how you might approach this. 


If you decide not to go ahead, you will need to make this clear and our template letter for school may be of use. (See link below.)


You might want to consider getting your child a card from the Control Group, to help them assert their position in your absence.
