Childhood deaths from two leading bacterial causes of pneumonia and meningitis, pneumococcus and Hib, declined sharply during the period 2000 to 2015, especially as vaccines against these pathogens were introduced in high-burden countries, according to new estimates from a team led by scientists at Johns Hopkins Bloomberg School of Public Health.

The findings, published in The Lancet Global Health on June 11, highlight the success of the global fight against these illnesses, and also provide a clear picture of the remaining disease burden, now largely concentrated in South Asia and Africa.

[...] Wahl and colleagues developed updated estimates -- on a country-by-country basis, for each year from 2000 to 2015 -- of the numbers of Hib and pneumococcal disease cases and deaths in children. They used country-specific figures of children who died of pneumonia and meningitis, along with field-based evidence on the fraction of those deaths caused by pneumococcus and Hib, and WHO/UNICEF estimates of vaccine coverage to estimate the burden of pneumococcal and Hib deaths and cases.

Their primary findings were that both Hib and pneumococcus caused far fewer cases of severe disease and death in children ages one to 59 months in 2015 compared to 2000. For Hib in 2015, there were approximately 29,500 child deaths, and for pneumococcus an estimated 294,000 child deaths. These figures suggest declines of 90 percent and 51 percent, respectively, from the estimated deaths in the year 2000.

[...] The researchers estimated that during 2000-2015 PCV prevented a total of about 250,000 child deaths -- mostly after 2010 -- while Hib vaccines prevented 1.2 million child deaths. These figures do not include the prevented cases of pneumococcal and Hib deaths among children who were HIV-infected.

The new estimates will guide ongoing efforts to reduce the burdens of Hib and pneumococcal diseases, which together still kill approximately 900 children per day around the world. The estimates suggest, for example, that about half of the pneumococcal child deaths in 2015 occurred in just four countries: India, Nigeria, Democratic Republic of the Congo and Pakistan. "The pneumoccocal disease burden is now limited to a small number of countries that have not introduced the vaccine or have not yet fully scaled the vaccines," Wahl says.

    The article did not factor in things like improvements in sanitation, water quality, and nutrition. The article reads more like a pharmaceutical commercial than science, because sanitation, quality water, and good nutrition don't come with a high recurring price tag.

    Then you did not read the article.

    The sharp declines in child mortality from Hib and pneumococcus were due not just to the introduction of vaccines but also to general factors that have reduced pneumonia and meningitis deaths from all causes, such as better hygiene and access to health care. "In 2015 compared to 2000 fewer children died from all causes, not just Hib and pneumococcus," Wahl notes.

    However, there was evidence that vaccines were specifically responsible for a considerable reduction in mortality. "The estimated average annual decline in child deaths from pneumococcus jumped from 3 percent during 2000-2010 to 8 percent after 2010 when many high-burden countries began widespread immunizations with PCV," Wahl says.

      whatever. it's the same bullshit that happened with polio. i'm not saying that some vaccines don't work, but that the cdc and big pharma are lying scum.

      I skimmed the article (short on time), but didn't see that. Thanks for the reference.
