AB OBJECTIVES: In Brazil, jet injectors are routinely used among military
recruits and mass immunization campaigns which include residents of
rural Amazon. Conditions for optimal use of injectors are present in
several settings and military recruits, but not in the Amazon. We
conducted a study to compare the potential risk of transmission of HIV
and other blood-born diseases by jet injectors in these diverse
vaccination conditions. METHODS: Ped-O-Jet injectors were used as per
routine among military recruits and Amazon residents. The injection site
was visually examined immediately after the injection for evidence of
obvious bleeding. In addition, instead of administering the next dose of
vaccine to a person, we collect it in a test tube this dose was tested
qualitatively for the presence of blood using a dipstick which can
detect from 0.002 to 0.01 microliters of blood per 0.5 ml of vaccine.
RESULTS: A total of 2815 persons were studied after jet gun injection
among 12 different immunization sessions among military recruits and 30
persons in one session among Amazon residents. The rate of immediate
bleeding was also higher among Amazon residents 23% compared to 3.4%
among military recruits. The rate of occult blood was also higher among
Amazon residents, 6.6% vs. 1% in military recruits. CONCLUSION: Given a
rate of occult blood of 1%, this translates into a theoretical risk of
HIV transmission under conditions of optimal use. the HIV prevalence in
Brazilian children (from 2 to 14 years old) estimated to be 7-14/100.000
pop and taking to account the rate of HIV transmission by needlesticks
in health care workers estimated to be 0.3%, we estimated the
theoretical risk of HIV transmission through the use of Ped-O-Jet
injectors to be in the range between one per 238 to 476 million
injections. This results suggest that the use of jet injectors in this
vaccination strategy and military recruits are safe. The HBV prevalence
in the Amazon region is as high as 15%, based in findings, we estimate
the risk of HBV transmission at one per 388 to 3367 Ped-O-Jet
injections. Jet injectors are no longer recommended for use in the
Amazon area.
