Aaron G. Cass,Leon J. Osterweilillion deaths primarily in developing countries. Before the advent of measles vaccine some 30 years ago, these figures were roughly three times higher. Attenuated measles virus (MV) strains, all quite closely related to the original Edmonston isolate, have a very good record as a safe and highly eff

Harald Störrleation coverage was sufficiently high to reduce transmission of these viral infections . The reported incidence of measles decreased from 76 per 10 000 individuals in 1982 to 1.2 per 100 000 in 1988. Vaccination against measles had been introduced in Sweden in 1971 and was offered t

Mark Greenwood,Ian Robertsonmal models, temperature-sensitivity, cold adaptation, ability to induce interferon, presence of defective interfering particles as well as, most importantly, attenuation in human infection. The molecular (nucleotide sequence) basis of few, if any, of these changes has been elucidated. Recently descr

Giovanni A. Cignoniappreciation and perspective of what he or she might see and.Instead of taking somebody‘s word for it about the basic size and distance statistics for the solar system, this book shows amateur astronomers how to measure these things for themselves. This is an enriching experience for any amateur ast
