This video primarily focuses on vaccinating sheep in Tost village, situated at the foot of Tenger Mountain. In the past, herders and their livestock would move into the deep mountains during the summer. However, nowadays, instead of moving into the mountains during the summer and winter, herders prefer to stay at a lower altitude, such as Tost village, during the summer and in agricultural land during the winter. Consequently, the hot summer has led herders to spend more money on medicines and constantly vaccinate their sheep to protect from various diseases. This practice not only impacts the health of the livestock but also potentially affects the people who consume the meat.
