Hello, my name is***** and I have over 20 years of experience as a veterinarian. I understand that you wormed your puppy Browney this morning and would like to vaccinate your pup with canine imuno vax 5 vaccine this afternoon.
Ideally I would recommend waiting at least 48-72 hours between any treatments/medication. That way if your pup gets sick or has any sort of reaction you will know which product he is reacting to, and it is easier on his body to only have to handle one thing at a time.
Since you've already wormed him today I would wait until Tuesday or Wednesday before vaccinating him.
I also recommend watching him closely for any sign of a reaction (vomiting, diarrhea, hives, facial swelling or difficulty breathing) for several hours after giving your pup anything. If that's not possible during the week, then waiting until next weekend is best.
In the meantime I would recommend not walking him outside his yard, and only letting him come into contact with fully vaccinated dogs.
Please let me know if you have any further questions.
