The researchers reported in the British journal Nature that they inoculated 42 of the animals...
The work of the German researchers is also significant because it shows that killed viruses (which are far safer to use in a vaccine than live agents) apparently can be used to stimulate the monkeys' immune system into manufacturing antibodies against cancer viruses.
Even if it is proved that viruses cause human cancer, cautions Spiegelman, it may be years before science can develop a safe, successful vaccine against them. But identification of cancer viruses is likely to produce a payoff long before vaccines become practical. Spiegelman believes that the presence of viral particles...
It is one of the mottoes of a scientist that if something seems too good to be true, there is a high probability that it is not true. Few scientists appreciate the aptness of this more than Dr. Albert Sabin, 68, developer of the live-virus polio vaccine. Eighteen months...
Brazil produces no vaccine of its own; so far it is making do with 235,000 doses of type A vaccine imported from France and awaiting arrival of 300,000 type C doses from the U.S. That would hardly be enough to stem the meningitis tide. In São...
