Jane Goodall is a renowned researcher and primatologist known for her groundbreaking work with chimpanzees in Tanzania. In the early 1960s, Goodall's studies of wild chimpanzees at Gombe Stream National Park challenged established ideas about animal behaviour and human uniqueness. Goodall's work revealed tool use, hunting, and complex social behaviours in chimpanzees. During her time at Gombe Stream, Goodall faced a polio outbreak among the chimpanzees, which had been transmitted from humans. To contain the outbreak, she administered polio vaccines to the chimps, a challenging task due to the live vaccine's dosage requirements. This incident highlights the potential ethical dilemmas and responsibilities that arise when studying and interacting with wild animals.

Jane Goodall's polio vaccination drive for Tanzanian chimps
In 1960, Jane Goodall, a 26-year-old woman, travelled to Gombe Stream National Park in Tanzania to study wild chimpanzees. Goodall's research at Gombe Stream challenged two long-standing beliefs: that only humans could construct and use tools, and that chimpanzees were vegetarians. Goodall discovered that chimpanzees would use stalks of grass to "fish" for termites, and would strip leaves off twigs to make them more effective tools. She also observed that chimpanzees would hunt and eat smaller primates, such as colobus monkeys.
Goodall's methods were unorthodox; she named the chimpanzees and noted their personalities, rather than assigning them numbers. This helped her develop a close bond with the chimpanzees, and she eventually became the only human accepted into chimpanzee society.
In 1966, a polio outbreak occurred among the Tanzanian chimps at Gombe Stream. Goodall and her team traced the outbreak to two human polio victims in the south, who had passed the disease to the chimp population. The chimps would seize bananas from one another, which made administering the required three doses of the oral polio vaccine particularly challenging. Goodall and her team had to ensure that a high-ranking chimp who had just had a dose did not seize a banana from a low-ranking chimp that contained that day's dose. Despite their efforts, many chimps died, and at least one was euthanized.

The live polio vaccine's challenges
In 1966, Jane Goodall stopped a polio epidemic among Tanzanian chimps at the Gombe Stream Research Centre by administering an oral polio vaccine to them. The chimps had contracted polio from humans, possibly from fishermen and villages in the south. The vaccine was hidden in bananas, with the required number of drops in each banana. However, this was challenging because the vaccine was a live vaccine, and if a chimp received a second dose too soon after the first, they could get polio. Therefore, there had to be a week's space between doses. This was difficult to manage because high-ranking chimps would sometimes seize bananas from low-ranking chimps. Goodall's team lost many chimps to the disease, which had a devastating impact on the population at Gombe Stream, which never had many chimps to begin with.

The outbreak's impact on Gombe Stream's chimps
Jane Goodall's research at Gombe Stream challenged the idea that only humans could construct and use tools, and that chimpanzees were vegetarians. Goodall observed a hunting group of chimpanzees isolate a colobus monkey high in a tree and block all possible exits. One chimpanzee then climbed up, captured, and killed the colobus. The others then took parts of the carcass, sharing with other members of the troop.
Goodall also observed the tendency for aggression and violence within chimpanzee troops. She observed dominant females deliberately killing the young of other females in the troop to maintain their dominance, sometimes resulting in cannibalism. Goodall's observations of chimpanzee behaviour in the Gombe Stream National Park of Tanzania provided vital insight into the evolution of our own species.
In 1966, a polio outbreak among Tanzanian chimps was traced to two human polio victims. The disease was transmitted from fishermen and villages in the south, spreading from chimp to chimp until it reached Gombe Stream. Goodall and her team immediately obtained the polio vaccine from Nairobi and administered it to the chimps via bananas. However, the vaccination process was challenging due to the required spacing between doses and the risk of high-ranking chimps seizing bananas from low-ranking ones. Despite their efforts, the outbreak had a devastating impact on the Gombe Stream chimp population, with many casualties.
The polio outbreak at Gombe Stream was a traumatic event that highlighted the vulnerability of chimpanzee communities to human diseases. It also underscored the importance of proactive disease prevention and management strategies to protect both human and chimp populations. The experience further reinforced Goodall's commitment to the humane treatment of animals and the preservation of their natural habitats.

The role of the European doctor
Jane Goodall's work in the Gombe Stream National Park in Tanzania in the early 1960s revolutionized the field of primatology. Goodall's research challenged long-standing beliefs about chimpanzees and forced a re-evaluation of our understanding of what it means to be human. Goodall's work was also significant in opening doors for women in science.
In 1966, a polio outbreak among Tanzanian chimps was traced to two human polio victims. The disease was transmitted from fishermen and villages in the south to the chimp population, resulting in devastating casualties. During this outbreak, a European doctor in Kigoma played a crucial role. The doctor was responsible for administering polio prevention drops to the human population in the region. However, he failed to do so, and as a result, the outbreak spread to the chimps.
Goodall and her team were initially unaware that polio was present in the human population due to the doctor's failure to report the outbreak. Once they realized it was polio, they acted quickly to obtain the vaccine from Nairobi. They administered the required doses to the chimps by putting the drops into bananas. This intervention was challenging due to the need for multiple doses spaced a week apart to ensure the chimps' safety. Despite their efforts, Goodall's team lost many chimps to the disease, which had a devastating impact on the population at Gombe Stream.

Jane Goodall's work with chimpanzees
Jane Goodall is an ethologist and conservationist who has redefined what it means to be human and set the standard for how behavioural studies are conducted through her work with wild chimpanzees. Goodall's work with chimpanzees began in 1960 when she travelled to Gombe Stream National Park in Tanzania to observe wild chimpanzees. Goodall's research challenged two long-standing beliefs: that only humans could construct and use tools, and that chimpanzees were vegetarians. She discovered that chimpanzees engage in toolmaking, cooperative hunting, and even warfare. Goodall also observed the tendency for aggression and violence within chimpanzee troops, including dominant females deliberately killing the young of other females in the troop to maintain their dominance, sometimes resulting in cannibalism.
Goodall set herself apart from other researchers by naming the animals in her studies instead of assigning them numbers, which was the nearly universal practice at the time. This approach allowed her to develop a close bond with the chimpanzees and become the only human ever accepted into chimpanzee society. She was the lowest-ranking member of a troop for 22 months. Goodall's discoveries were brought to the public's attention by a 1965 National Geographic television documentary, which made her internationally prominent and silenced her doubters.
Goodall's work with chimpanzees also extended beyond her research. In 1977, she established the Jane Goodall Institute (JGI), a global community-centred conservation organisation. JGI's program Roots & Shoots, established in 1991, encourages young people worldwide to participate in projects that protect the environment, wildlife, or their communities. Goodall has also been an advocate for improving the conditions for chimpanzees held in medical research facilities and has helped set up several refuges for chimps orphaned by these facilities or the bushmeat trade. Today, Goodall continues to raise awareness and money to protect chimpanzees, their habitats, and the planet.
In addition to her work with chimpanzees, Goodall has also had a significant impact on the field of primatology. When she began her research in the late 1950s, women were not accepted in the field. Today, thanks in part to Goodall's trailblazing and encouragement of young women to join, the field of primatology is made up of almost equal numbers of men and women. Goodall's unconventional approach to her research and her willingness to challenge traditional beliefs have made her a pioneering figure in the study of chimpanzees and our understanding of human evolution.
