Schedule, dosage, storage and effectiveness of TT vaccine
If given as a separate vaccine to pregnant and non-pregnant women of childbearing age, at least two doses of 0.5 ml of TT vaccine are given intramuscularly (IM) into the upper arm (Figure 2.7); but for maximum long-lasting protection throughout the childbearing years women should receive more than two doses (TT2+), and the ideal is to give five doses. It should be stored at between +2oC and +8oC and never frozen. Table 2.6 summarises the characteristics of TT vaccine; the periods of protection after each dose are given in Table 2.7.
Figure 2.7 Make sure all pregnant women are immunized against tetanus.
