I think there are many aspects. I think the health of children has been overlooked overall, as my colleagues described.
It's a limited impact. I can only take the example of respiratory syncytial virus, on which we heard a lot. I have been working on that for 20 years now. It was widely overcome before, because we said it's a limited number of children who will be impacted. Also, indigenous people are highly impacted by this, compared to the general population.
In my opinion, what is widely overcome is what you just described before, which is the impact of comorbidities on the health of children in general, like the food they get all their life, together.... All of this impacts the capacity to fight the disease that will not impact a child, whilst all the good food and everything will make a good immune system to fight all of that.
It's more the correlation between.... We have a lot of research on specific diseases, but we always ignore that not all children are equal in the face of disease. We need to get a diversity of information about how children will respond in their capacity to fight different diseases, depending on their backgrounds and their lifestyles. That's something we have to put more emphasis on in research.
