In a controlled laboratory study, a similar serological response to vaccination with
modified live canine adenovirus type-2 (CAV), canine distemper virus (CDV), canine
parvovirus (CPV) and inactivated rabies virus (RV) was observed when 6-month-old
vaccine naïve puppies were administered the veterinary medicinal product at 3.6
mg/kg atinvicitinib (3 times the maximum labelled dose) once daily for 84 days,
compared to dogs receiving the vaccines alone. The veterinary medicinal product
was well-tolerated with no adverse clinical effects related to treatment when used
concomitantly with vaccination.
