Stable Recombinant Avirulent Salmonella Vaccine Strains
1989All infectious disease agents have specific mechanisms to colonize , invade , and overcome the host. By use of gene cloning and genetic and biochemical techniques , it is possible to elucidate these mechanisms in biochemical terms as well as to understand the biology by which pathogens accomplish these feats .

Selection of influenza vaccine strains and developing pandemic vaccines
Vaccine, 2002The WHO Influenza Surveillance Programme has recently celebrated 50 years of success. The programme provides representative influenza viruses for antigenic and genetic analysis and from this information, the WHO is able to make recommendations on vaccine composition.

Orally administrable brucellosis vaccine: Brucella suis strain 2 vaccine
Vaccine, 1986An orally administrable brucellosis vaccine, Brucella suis strain 2 vaccine was developed in China. The characteristics and merits of the vaccine are described. It is effective for oral vaccination of sheep, goats, cattle and pigs and has been widely used for prevention of animal brucellosis in China over the past 15 years. About 30-40 million doses of

Mixed populations in influenza virus vaccine strains
Vaccine, 1994Human influenza viruses used for vaccine production have previously been adapted to grow in eggs. During egg adaptation, variants are selected and we have observed that more than one variant may derive in a single egg resulting in a mixed population. We have now investigated the extent of heterogeneity, due to host cell selection, of virus strains used

Mumps vaccine virus strains and aseptic meningitis
Vaccine, 2006Mumps immunization can easily be included in national schedules, particularly if combined with measles or measles and rubella vaccines, but debate continues concerning the relative safety of various licensed mumps vaccine strains. The opportunities for control of mumps are also being affected by differences in the cost of the vaccines prepared with ...

Vaccine escape of piliated Streptococcus pneumoniae strains
Vaccine, 2016Type1-pilus proteins were suggested as targets of future protein-based vaccines. Here we studied the effect of pneumococcal-conjugate vaccine (PCV7) implementation on the prevalence of piliated strains in a unique study setting which controls for typical confounders; the Palestinian-Israeli Collaborative Research (PICR).Annual cross-sectional surveys ...

Cendehill strain of rubella vaccine: Clinical evaluation
The Journal of Pediatrics, 1969Rubella vaccine, the Cendehill strain, was evaluated clinically and by measuring the hemagglutination-inhibition antibody response in the sera of both children and young women. In both groups of susceptible individuals, an antibody response occurred in over 99 per cent. The titer in children has remained fairly constant for at least 9 months.

Virulent HIV Strains, Chimpanzees, and Trial Vaccines
Science, 1999We would like to comment on the controversy concerning the use of a virulent strain of human immunodeficiency virus (HIV) to assess the protective efficacy of candidate HIV vaccines (A. M. Prince and L. Andrus, Letters, Science 's Compass, 18 Dec. p. [2195][1]; N. L. Letvin, ibid. ).
