Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Lethargy, fever and inappetence can occur 24-48 hours post-vaccination. This is not uncommon. If it has been longer than this, it is likely unrelated to the vaccines that a good reason to have Saski evaluated by your veterinarian to ensure that there is not something else going on. Good luck! Have a good evening!
