The Disease Control and Prevention (CDC) is an agency in the United States that focuses on protecting public health and preventing the spread of diseases. While the CDC does not directly participate in the vaccine market, it plays a crucial role in the development, distribution, and recommendation of vaccines. The vaccine market is a broad industry that involves the research, development, production, and distribution of vaccines to prevent various diseases. Both public and private entities participate in the vaccine market, including pharmaceutical companies, research institutions, government agencies, and international organizations.
