Wilbur is a relatively safe vaccine. It is an inactivated vaccine, which is relative to an attenuated vaccine. Attenuated vaccine is a vaccine that weakens the toxicity of virus, makes it not highly contagious, and stimulates the body to produce antibodies, which has certain risks. For example, rabies vaccines for animals in China are mostly of this kind. Inactivated vaccine, as its name implies, means that the virus has been inactivated and does not have the ability to infect, but it can stimulate the body to produce antibodies, so it is safe.
If you are still worried, you can do antibody testing after all 5 injections, and it will be OK if it is positive.
For your health:) Be careful in the future. If you are so scared, don't provoke small animals:)
