“…During operation, the cooling water pressure was formation (3,6) and give protection (24), but it kept at 15 to 20 psi. The feeding pressure into the has also been reported that one purified and rotor varied between a suction of 7 psi and a pressure concentrated killed vaccine, although it induced of 20 psi.…”

“…Attempts to prepare inactivated rubella virus vaccines by treatment with formalin or ethylene oxide, both of which denature protein, have met with little success (Sever, Schiff and Huebner, 1963 ;Frankel, 1964;Meyer and Parkman, 1967). Photodynamic inactivation, in the presence of sensitising, cationjc dyes, is a relatively simple and yet efficient technique which acts by preferentially damaging viral nucleic acid, leaving surface protein immunogenicity virtually intact.…”
