High-income countries were able to fully vaccinate their populations due to the higher dose allocation, raising concerns about unequal access to life-saving vaccines.
A new study suggests that larger conservation areas are ineffective in protecting threatened species in central Africa, citing a lack of funding and resource management issues. The research found that broader conservation efforts often led to decreased populations due to the lands being too large to manage effectively.
