The Australian Immunisation Handbook 10th Edition 2013

Interruption to a vaccination
If the process of administration of a vaccine given parenterally (IM or SC) is
interrupted (e.g. by syringe–needle disconnection) and most of the dose has not
been administered, the whole dose should be repeated as soon as practicable.
If most of an oral rotavirus vaccine dose has been spat out or vomited within
minutes of administration, a single repeat dose can be administered during
the same visit. If an infant regurgitates or vomits only a small part of a dose
of oral rotavirus vaccine, it is not necessary to repeat the dose. Therefore, the
regurgitated (and incomplete volume) dose is still considered as the valid dose
(see 4.17 Rotavirus).
2.2.6 Recommended injection sites
The choice of injection sites depends primarily on the age of the person to be
vaccinated. The two anatomical sites recommended as routine injection sites are
the anterolateral thigh (Figures 2.2.5 and 2.2.6) and the deltoid muscle (Figure
2.2.8). Immunisation service providers should ensure that they are familiar
with the landmarks used to identify any anatomical sites used for vaccination.
Photographs and diagrams are provided in this section, but are not a substitute
for training. Further detail on identifying the recommended injection sites is
provided in 2.2.8 Identifying the injection site.
