Go to Breeding - Vaccination program:



Here you put in your own code for the vaccination program, then you choose at what age the animal is vaccinated (in weeks), put in a checkmark in Boar and/or Sow if both are vaccinated with this, enter the dosage and then choose the journal. You can use F5 to search for the correct journal. 


The journal must be created in General - Medicine/Vaccination - Journal before it can be added here. see here how to do this: Quick guide to medicine registration
