Vaccines and antibiotics have saved the lives of many people. Fifty years ago many people became crippled or died from polio. Now the polio vaccine is available everywhere. In the past people could die from even simple infections. Now penicillin and other antibiotics make it easy to cure infections. Increased access to health care has also improved the lives of millions of people. In the past many people lived far from hospitals or clinics. Now hospitals clinics and health centers have been built in many pails of the world. More people have the opportunity to visit a doctor or nurse before they become very sick. They can be treated more easily. They are sick less and this leads to a better quality of life. Improved surgical techniques make it easier to treat many medical problems. Microscopic and laser surgery techniques are more efficient than older methods. It is easier for the doctor to perform them and easier for the patient to recover. Surgery patients can return to their normal life more quickly now than they could in the past. Everybody needs good health in order to have a good quality of life. Advances in medical science have improved the lives of people all around the world. They are improvements that are important to everyone.
