Two types of combined vaccines are given to provide tetanus immunization along with protection other specific bacterial infections. The first is the Td to protect against tetanus and diphtheria infection. The second is the Tdap, which protects against tetanus, diphtheria and pertussis infections. The Centers for Disease Control and Prevention point out that the most noticeable side effects of the vaccine include flu-like symptoms but these are considered to be mild.
Fever
A fever occurs in about one out of every 25 adolescents and one out of every 100 adults who receive the Tdap, according to the Centers for Disease Control and Prevention. The temperature is typically mild and stays around 100.4 degrees. About one out of every 15 recipients of the Td vaccine will have a mild fever. About one out of 100 adolescents and one out of 250 adults will have a fever over 102 degrees with the Tdap vaccine. A fever over 102 is rare in recipients of the Td shot. Medical attention is not necessary in these situations. A fever higher than 102 degrees or one that persists despite attempts to reduce it require medical attention but is highly unlikely.
Headache
A headache is more common than a fever in recipients of the Tdap, but it isn't very common with the Td vaccine, suggests the Centers for Disease Control and Prevention. More adolescents will have a headache than adults who receive the Tdap. Headaches and other flu-like symptoms are not considered severe or in need of medical attention unless the pain is significant or persistent.
Fatigue
Fatigue is relatively common following the Tdap. It occurs in about one out of three adolescents and one in four adults states the Centers for Disease Control and Prevention. This symptom is not as likely in recipients of the Td vaccine.
Abdominal Symptoms
Abdominal discomfort isn't likely for those receiving the Td vaccine. Individuals who get the Tdap may experience mild nausea, vomiting, diarrhea and stomachache. These symptoms are generally short-lived and only occur in about one out of four adolescents and one out of 10 adults, as indicated by the Centers for Disease Control and Prevention.
Irritability
The New York Times points out that children may be fussy following the the tetanus vaccine. This can include fussiness and persistent crying. Crying should not continue beyond a few hours in normal cases.
