SDG 3 provides healthy lives for all ages through better access to healthcare, disease reduction, and mental health. Some major targets include reducing maternal and child mortality, halting epidemics, and ensuring universal health coverage. Vaccines, sanitation, and prevention of diseases are most important. Healthcare infrastructure needs to be invested in by governments, and people can have healthier lifestyles. A healthy population is the key to economic progress and social peace. We can create a world where all live and prosper.
