This NebGuide explains the basics of veterinary vaccine syringe cleaning and care.
Inadequately cleaned vaccine syringes are often responsible for localized infections associated with vaccination. Swellings around the injection site is common, especially when killed vaccines such as clostridial bacterins are given subcutaneously. Generally, these swellings can be considered good evidence that the animal is developing a proper immune response, but if the injection site swelling is greater than a small hen's egg, the swelling may be due to infection and should be examined.
