criminal negligence - (law) recklessly acting without reasonable caution and putting another person at risk of injury or death (or failing to do something with the same consequences) culpable negligence.
The Bordetella vaccine is administered together with the other core vaccines and it may take up to 7 days before the vaccine will be effective, so make sure you plan ahead if you intend to take part in shows or take your pet to a daycare.
The time of effectiveness on vaccines is a controversial issue. Some believe that vaccines in fact can last the entire dog's life. But it's recommended to get yearly boosters on most vaccines, 3-year booster on some rabies vaccines, and 6-month boosters on certain bordatella vaccines. If it's not required, then I wouldn't worry about it since it's only been about 3-4 months.
