All three options mentioned - Vaccines, Wearing masks, and Washing hands - are highly cost-effective ways of maintaining public health.

1. Vaccines: Vaccines are a cost-effective solution for public health as they prevent diseases rather than treating them. They work by training the immune system to recognize and combat pathogens. By preventing diseases, vaccines reduce the cost of healthcare expenditure significantly.

2. Wearing Masks: Especially in the context of airborne diseases like COVID-19, wearing masks is a simple and cost-effective method to prevent the spread of diseases. Masks act as a physical barrier to protect you and others from viral and bacterial particulates.

3. Washing Hands: Regular hand washing is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others. It's quick, it's simple, and it can keep us all from getting sick. Hand hygiene is a great way to prevent infections.

Therefore, all three are cost-effective strategies, but their effectiveness can be maximized when they are used in combination.
