Injecting, what’s the theory?
Most vaccinations in piglets are administered intramuscularly in the neck, behind the ear.
Modern vaccines contain well designed and safe adjuvants which are usually free of negative side-effects.
Advantages of registered fresh mixable combi-vaccines for pigs are:
- Reduction of number of injections for Circovirus and Mycoplasma
- Less handling-stress as the result of less handling of piglets

Injecting pigs, what happens in practice?
The dose-volume and adjuvant of modern vaccines are designed for suckling pigs. The efficacy of the vaccination therefore depends on the site of injection. Injection-needles should be changed between each litter that is vaccinated.
Intramuscular injection in the neck, behind the ear base.
Blunt or bent needles increase tissue-damage and the risk of infection/inflammation. This may lead to the development of injection site abcesses.
