Which public health milestone occurred in 1964?

• A. The US Surgeon General's advisory on smoking and health
• B. The polio vaccine trial
• C. AIDS guidelines
• D. CDC established

Answer: (A)

The main idea is how a single, authoritative public health statement can shift risk perception and drive policy. In 1964, the U.S. Surgeon General released a landmark advisory linking smoking to serious diseases like lung cancer and heart disease, making it clear that smoking was a public health issue affecting the whole population. This changed how people viewed smoking and prompted a wave of health actions and policies—such as warning labels on tobacco products, advertising restrictions, and public health campaigns aimed at reducing smoking. Those other events did not happen in 1964: polio vaccine trials occurred in the 1950s, AIDS guidelines appeared in the 1980s, and the organization now called the CDC has roots dating back to 1946. The 1964 Surgeon General’s advisory is why that year is remembered as a major public health milestone.
