From the British Medical Journal dated Oct 1970.
"Though smallpox vaccination by jet injection is accepted in the U.S.A." it is
rarely carried out in Britain, partly because
of problems associated with the dilution of vaccine LYMPH to
volumes which can be used by jet injectors, and partly because
LYMPH is NOT necessarily bacteriologically sterile and has,
therefore, been regarded as unsuitable for intradermal inoculation."
