Prevention is better than cure. Researching and treating diseases is too costly, so it would be better to invest in preventive measures. 

To what extent do you agree or disagree?

It is argued that preventive healthcare should be the main focus of the healthcare system instead of medical research and treatment due to the latter being too expensive. While I agree that preventive measures are necessary to stop diseases from spreading and lower healthcare expenditure, I also believe that allocating financial resources to research and treatment should continue despite their high costs. 

On the one hand, taking precautions will reduce the spending on healthcare by keeping people’s wellness under control and preventing diseases before they occur. For instance, vaccines, one of the most used such measures, trigger the production of disease-fighting antibodies by the immune system and result in lower severe cases of illnesses and hospitalization, thus reducing the spending on healthcare. Other preventive methods also effectively lower the chance of chronic diseases such as type-2 diabetes, which are usually caused by a sedentary lifestyle and obesity. Simply put, if people exercise regularly and keep their weight in check, they will have much fewer health issues and consequently lower the expenditure on healthcare. Therefore, I believe that prevention brings nothing but benefits to people and the healthcare system.

On the other hand, some effective preventive measures would not exist without proper research. Also, treatment sometimes addresses specific diseases or problems that prevention can’t eliminate. For example, a highly effective vaccine such as that of Pfizer, which was developed for Covid-19, takes a lot of research and millions of dollars worth of production equipment to be developed and finally available for public use. Furthermore, preventive healthcare cannot address hereditary diseases like type-1 diabetes. Such illnesses can only be treated with expensive medications. Therefore, I firmly believe that research and treatment projects are essential to the advancement of medical science and should not be replaced by anything else.

In conclusion, prevention is an effective way of keeping people healthy and the costs down; however, research and treatment are not only needed to develop effective preventive measures but also vital for some people.
