Thank you for submitting your question regarding Toby. Vomiting can indicate a vaccine reaction depending on how close it occurs in relation the vaccination. I recommend contacting his veterinarian. If there is a concern of him having reaction, then it will be recommended that he returns to the clinic for further treatment. If not, he could have experienced car sickness or an upset stomach due to something he ate. If he is coughing, then he may have an upper respiratory infection or have nasal irritation from the Bordetella vaccine. I hope this information helps!
