Hey,
Your ideas in this paragraph are spot on. I like how you specifically make mention to how education would mean individuals are more likely to intrecpet health literacy and hence make decisions such as vacination.
My only suggestions, would be to
-Signpost individual, national and global health
-Make the interrealtionship clear by refering back to individual health and wellbeing at the end
Below is something I would have written:
Quality education would provide people with the skills to be able to interpret health literacy and hence they would be more likely to make consious decsions such as getting vacinated for conditions such as influenza. This contributes to individual health and wellbeing, as it would mean that indviduals would spend less time living with diseases and reduce the instance of premature death. Consquently, through individuals chosing to be vacinated, it would reduce the possibiliy of them contracting communicable diseases, and hence requiring healthcare treatment. This contributes acts as a resourse nationaly as there is less demands placed on the healthcare system, inaddition to lower national healthcare costs. Furthermore, through peple understanding the importance of vaccinations, it contributed to improved global health and wellbeing as it can prevent the spread of communcable diseases between countries which inturn reduced the possibility of people contracting diseases which can hinder their individual health and wellbeing.
Hope this helps
