Viremia in a Recipient of HPV-77 Rubella Virus Vaccine
TLDR
To the authors' knowledge, this represents the first isolation of rubella virus from the blood of a recipient of HPV-77 vaccine, and the consistent antibody responses among vaccinees and the regular presence ofrubella virus in their pharynges argue that viremia occurs in almost every susceptible recipient.Abstract:
A live rubella virus vaccine, HPV-77 (High Passage Virus - 77 tissue culture passages) was administered subcutaneously to eight rubella-susceptible children housed in an isolation ward. One blood specimen, taken on the tenth day after vaccination, from one of the eight vaccines, yielded a rubella virus. This virus had laboratory markers which were "vaccine-like." To our knowledge, this represents the first isolation of rubella virus from the blood of a recipient of HPV-77 vaccine. However, the consistent antibody responses among vaccinees and the regular presence of rubella virus in their pharynges argue that viremia occurs in almost every susceptible recipient. The most logical explanation for the failure to document viremia in other recipients of HPV-77 vaccine is that the viremia is ordinarily low grade or transient or both.read more

Viremia, Virus Excretion, and Antibody Responses after Challenge in Volunteers with Low Levels of Antibody to Rubella Virus
TL;DR: The risk of viremia after challenge in individuals with low levels of rubella antibody appears to be low but may be higher than usual when immunity is induced by rubella vaccine.

TL;DR: Five children challenged by intranasal administration of pharyngeal secretions containing 100 tissue culture interfering dose 50's of rubella virus 8 to 12 months after the five had received HPV-77 vaccine had significant increases in HI, neutralizing, and complement fixing antibodies.

Safety of Administering Live Vaccines during Pregnancy: A Systematic Review and Meta-Analysis of Pregnancy Outcomes
TL;DR: Overall risks appear to be small and have to be balanced against potential benefits for the mother-infant pair, but quality of evidence was very low.

TL;DR: A study at Marine Corps Recruit Depot an Diego was conducted to determine the incidence and duration of vaccinenduced viremia, as well as identify any circulating strains of denovirus.

Recovery of rubella virus from army recruits.
TL;DR: A virus recognized by its capacity to multiply in grivet monkey kidney cultures and to interfere in such cultures with subsequent multiplication of ECHO-11 virus, was isolated regularly from military recruits with rubella, but rarely from those hospitalized at the same time and place with scarlet fever.

TL;DR: Although early attempts to produce a killed-virus vaccine were unsuccessful, development of a live-Virus vaccine seemed feasible, and approaches that had been used to attenuate other viruses were explored.
