Is the H1N1 flu vaccine a live vaccine?

Generally speaking, the H1N1 influenza vaccine refers to the Influenza A (H1N1) virus split vaccine. The Influenza A (H1N1) virus split vaccine does not belong to Category I vaccines, but rather to Category II vaccines. Detailed explanation is as follows:

In China, vaccines are divided into two categories. Category I vaccines are those provided free of charge by the government to citizens, who are required to receive according to government regulations. These include vaccines determined by the national immunization program, vaccines added by provincial governments during implementation of the national immunization program, and vaccines used in emergency vaccinations or mass preventive vaccination campaigns organized by governments at county level or above, or their health administrative departments, such as hepatitis B vaccine, bacillus Calmette-Guérin (BCG) vaccine, and polio vaccine. Category II vaccines refer to other vaccines that citizens receive voluntarily and pay for themselves. The Influenza A (H1N1) virus split vaccine belongs to this category and requires citizens to bear the cost and choose to receive it voluntarily.

However, during special periods or in specific regions, such as during major public health events like a large-scale outbreak of Influenza A (H1N1), the government may provide this vaccine as part of emergency or mass preventive vaccination programs, with the government covering the cost for free vaccination. However, this does not change its classification as a Category II vaccine under normal circumstances.
