In the process of vaccine research and development in China's scientists and technicians to change the traditional serial mode to parallel mode.

Vaccines are biological products made from various types of pathogenic microorganisms for preventive inoculation. Among them, vaccines made with bacteria or spirochetes are also known as bacteriophages. Vaccines are divided into live and dead vaccines. Commonly used live vaccines include BCG, polio vaccine, measles vaccine, plague vaccine and so on. Commonly used dead vaccines are pertussis vaccine, typhoid vaccine, influenza vaccine, cholera vaccine and so on.

The production time varies for different vaccines:

The production time varies for different vaccines, and some may take up to 22 months to produce a batch. Vaccine development is a long, complex and costly process. Vaccination is the most cost-effective and efficient public **** health intervention to prevent and control infectious diseases, and for families it is also an effective means of reducing the incidence of disease in their members and reducing health care costs.

It is estimated that immunization averts 2 to 3 million deaths per year from diphtheria, tetanus, pertussis and measles. Global vaccination coverage (the percentage of children worldwide who receive recommended vaccines) has remained stable over the years.
