Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If you think Jasper is acting strange and is having a possible reaction to the vaccination, I would take him back to the veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps!
