Also in the news: new meningitis vaccine?; ethics of clinical trials

Two other odds-and-ends appearing in our inbox this week:

-- An AP story from late last week proclaims, "New meningitis shot could end fatal epidemics." Not surprisingly, "could" is very much the key word in that headline. As the story points out, the positive data being announced comes from a clinical trial of only 600 toddlers in Africa, and the successful introduction of the vaccine candidate is, at best, years away. More depressing, but no doubt accurate, is this point from the story:

"Even if the new vaccine becomes available, experts think there will be a lag of about 15 years before the majority of Africa’s at-risk population can be vaccinated."

Of course, this 'lag' is present for the introduction of any new vaccine in the developing world, often (as is the case for rotavirus and HPV vaccines) the parts of the world where the greatest vaccine-related benefit is possible.

-- Speaking of vaccine research and testing in the developing word, the June 21 issue of Vaccine includes a paper titled, "Ethical considerations related to the provision of care and treatment in vaccine trials." (subscription required). Written by Daniel Tarantola, Ruth Macklin, and colleagues, the paper summarizes a meeting exploring the long-disputed question of the type and level of care due to research subjects in the developing world (where the standard of care is typically quite different from the home countries of research sponsors.)

Those looking for a clear recommendation will not find it here. The authors recommend "a structured approach" to decision-making, meaning, "a consultative process with trial communities and other stakeholders in research [that] will ensure that the needs and legitimate expectations of trial participants are appropriately met, obligations towards them are delivered and, as a result, ethical research is facilitated in the interest of public health."
