Difference between single vaccine and combined vaccine for pigs

There are obvious differences between single vaccine and combined vaccine in prevention scope, price and immune effect.

1. Scope of prevention: A single vaccine can only prevent one disease, and a combined vaccine can prevent multiple diseases at the same time.

2. Price: The price of a single vaccine is usually lower than that of a combined vaccine, because the process required to produce a single vaccine is relatively simple and the cost is lower.

3. Immune effect: From a scientific point of view, the combined vaccine has a stronger immune effect, because it contains a variety of antigens, which can stimulate the immune system to produce a stronger response, thus producing a more lasting immunity.

Generally speaking, the choice of single vaccine or combined vaccine needs to be decided according to the specific disease risk and prevention and control needs.
