How many tetanus shots are given to adults after being bitten by a dog? - briefly
Adults who have been bitten by a dog typically receive one tetanus shot if their last tetanus vaccination was within the past five years. If it has been more than five years since their last tetanus vaccination, they may need to receive two shots, with the second shot given one month after the first.
How many tetanus shots are given to adults after being bitten by a dog? - in detail
After sustaining a dog bite, it is crucial for adults to receive appropriate medical attention to prevent potential infections, including tetanus. The number of tetanus shots required can vary depending on an individual's vaccination history and the severity of the bite.
For adults who have received their primary series of tetanus vaccinations and a booster within the past 10 years, no additional tetanus shot is typically needed following a dog bite. However, if more than 5 years have passed since the last booster, it is recommended to receive a single dose of tetanus-diphtheria (Td) vaccine.
In cases where an adult has not completed their primary series of tetanus vaccinations or has not received a booster within the past 10 years, the Centers for Disease Control and Prevention (CDC) advises administering both tetanus immunoglobulin (TIG) and tetanus-diphtheria vaccine. TIG provides immediate protection against tetanus, while the vaccine stimulates the body's own immune response to produce long-term antibodies.
Additionally, if the dog bite is considered severe or at high risk for infection—for example, if there are signs of infection such as redness, swelling, or oozing—medical professionals may also prescribe antibiotics to prevent secondary infections.
It is essential to consult with a healthcare provider promptly after a dog bite to determine the appropriate course of treatment based on individual vaccination history and the specific circumstances of the injury.
