The majority of children who received the tetanus vaccine will get it through the DTaP shot. However, if parents choose to have their child receive the tetanus shot separately, they will receive the DT shot, which is given to individuals up to seven years of age. For persons older than seven, the Td or TENIVAC shot is used.

Three safety studies were cited. (p.2) The first had 163 infants given DT at 2, 4 and 6 months and acellular pertussis vaccine (aP) at 3, 5, and 7 months. One control group (n=85) received DT and aP at 2, 4, and 6 months while the other control (n=85) received DTwP at 2, 4, and 6 months and a placebo (undisclosed) at 3, 5, and 7 months.
The second trial had 52 children who had previously received 3 doses of DTP.
They received either aP (25) or wP (25) given at the same time at a separate site.
The third trial had 99 children who had received 4 doses of DTP. They received DT in one arm and wP in the other.
The first study followed the infants for only 24 hours and looked for and reported only for fever, crying, loss of appetite and injection site reactions. The latter two studies only observed for injection site reactions.
The DT evaluated in the clinical trials contained thimerosal.
DT has not been evaluated for carcinogenicity, mutagenic potential, or impairment of fertility (p.3)
Apnea following intramuscular vaccination has been observed in some infants born prematurely. (p.2)
Syncope (fainting) has been reported following vaccination with DT. (p.2)
Animal reproduction studies have not been conducted with DT. It is also not known whether DT can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. (p.3)
Adverse Reactions from Post-Marketing Experience (p.4)
In the previous package insert, only two studies were done, one with 20 subjects and the other with 40. The second study, compared infants given DTP, DT, DTP at 2,4, and 6 months, compared to infants who were give vaccine to kids who were given DTP, DTP, DT at the same ages. (The order of shots was varied.) They found the incidence of adverse reactions was significantly lower following the DT administration. Therefore it was claimed “safe” based on 60 infants and no placebo.
Sanofi Pasteur’s DT contains aluminum potassium sulfate, peptone, bovine extract, formaldehyde, thimerosal (in trace amounts), modified Mueller and Miller medium, and ammonium sulfate.
