How vaccines train the immune system in ways no one expected | Christine Stabell Benn | TEDxAarhus
Rating

Vaccines do much more than protect against the disease they are designed for. Watch this talk from TEDxAarhus 2018 by medical doctor and professor in global health Christine Stabell Benn and learn how hundreds of thousands of lives could be saved every year just by using the existing vaccines smarter. Christine Stabell Benn is a medical doctor and professor in global health. By studying real-life effects of vaccines in Africa, she has found that vaccines do much more than protect against the target disease; they have so-called non-specific effects. In most cases, they come with an added bonus of increased resistance against other infections than the target disease. If we take that into account, we can save hundreds of thousands of lives every year just by using the existing vaccines smarter. Christine argues that we should not only study vaccines' effects on the target infection, but also ask the often ignored question: what is the impact of vaccines on overall health?

Interview with William Howlett on HIV/AIDS in Moshi area, Tanzania1987inf
Rating

At the time of the video, 60 cases of AIDs had been documented at KCMC, arriving at an ever increasing rate since the first case in 1984. While the issue is tragic, the video provides a fascinating insight into the situation “at the front-lines.” The idea of an epidemic is just beginning to be considered. Understanding of the situation is in its early phases: how long is the incubation? How exactly is it spread? How can we treat it? Will there be a vaccine? Who is at risk?

Unlike in Europe and the West, AIDs in Africa is a heterosexual illness. Victims are adults of both sexes in their sexual prime. Howlett says that most of the cases he has seen have come from urban centres. People are beginning to understand that the full impact of the disease is invisible, because of the long incubation time from infection to full-blown disease. The tragedy of transmission to new-borns is just beginning to be observed.

The only defence against dying of AIDS, is to use condoms. Blood screening is starting to be implemented in major centres.

This video’s intended audience was humanitarian volunteers in Europe, intending to come to Africa. Howlett tells them that they need to be clear about their responsibilities to themselves and their families. That they need to understand potential, long-term impacts of any decisions they make. It is not the same situation, he says, as it was for volunteers 5-10 years ago.

Interview with William Howlett on HIV in Moshi area, Tanzania
Rating

As a medically trained humanitarian, Howlett first travelled to Africa in 1980. From 1984, he began as a Ministry-appointed specialist physician at Kilimanjaro Christian Medical Center (KCMC), in Moshi, in northern Tanzania. He has remained closely associated with KCMC ever since. Learn more about Howlett’s experiences.

In the first video, from 1987, he describes the beginning of the epidemic with the first officially documented case of HIV-AIDS that was diagnosed at KCMC in March 1984. In the third video from 2018, he cites UNAIDS statistics from 2016, to underline the scope of the epidemic. In Tanzania, a country of 55 million people, 1.4 million are HIV-infected. The UNAIDS statistics further indicate that in 2016, it is estimated that there are 55 000 new HIV-infections and 33 000 AIDs-related deaths annually.

Interview with William Howlett on the HIV epidemic in Moshi area, Tanzania 1989
Rating

Just 2 years later, Howlett is interviewed again. It is interesting to note how much understanding of the epidemic has grown in the 2 years since his first interview. Research and reporting is increasing. Howlett says that Tanzania has reported 2 500 cases thus far to WHO.

Focus is being placed on Public Education measures. It is beginning to be understood, to use metaphors, that AIDs cases represent just the tip of the iceberg for a disease that has an incubation time as long as 7-8 years, or longer. The epidemic is spreading from the main concentration of cases in urban centres, where there are high levels of promiscuity. Such areas with prostitution, travellers, mobile populations create “whirlpools” of infection and may have rates of infection in these high risk population groups more than 70%. The infection spreads from these urban nodes to rural areas, spreading in “ripples”, as travellers return home to their families.

A highly specific blood test has been developed to ensure safer blood supplies, although, Howlett explains, this is not a major transmission route in Africa.

Howlett says that the difference between the AIDs epidemic in Europe and Africa is largely cultural. In the West, he says, there is less promiscuity. In Africa, promiscuity is more tolerated, especially in “travelling” communities of truck-drivers and businessmen. Specific communities of sexual workers have become established in all urban centres. In a cycle of poverty, it may be the only choice available to many women. These women, Howlett explains, act as repositories, and the visiting men are the vectors spreading the disease along transportation routes and to their homes, in rural settings.

Howlett and his wife, Juliet, have become increasingly engaged in Public Education – holding talks in Public Meetings, developing education materials, reaching out to social leaders … However, he says that providing information is not enough to change behaviour – people have to understand the information and its implications for their lives and the lives of their family members.. Be responsible. Tests are available – get tested. Be celibate if you are HIV positive, or, at least, use a condom. All are equal before AIDs, he says. Nearly 100% of patients with AIDs die.

An Introduction to Global Health - Disease-specific Risk Factors - Part 1 of 2 (09:52)
Rating

Infectious diseases have a specific, ethiological cause, e.g. a microbe such as tuberculosis caused by Mycobacterium tuberculosis. However, most people exposed to TB does not develop the disease. What determines this may be poverty, weakening of the person by other diseases or smoking and alcohol. So-called life-style diseases are (also) determined by the way you live, and include prevalent non-communicable diseases such as type 2 diabetes and cardio-vascular diseases, but besides of risk factors such as smoking and drinking or over-eating, the living conditions matter equally and sometimes more. The environment, climate changes, urbanization, socio-economic factors all impact health and disease. When an individual grows older, patterns of his/her diseases changes: the same applies when a society grows ‘older’.

Previously infectious diseases previously caused the majority of ill-health and premature death globally, but in high- and middle-income countries during the 20.th century infectious diseases – with the exception of HIV – declined. Introduction of hygiene and discovery of microbes and later vaccines an antibiotics contributed to the decline, but changing living conditions with better housing, nutrition, water and sanitation were the main drivers of infectious diseases’ decline.
