A study for a hepatitis B vaccine is stopped. This is in Guinea-Bissau. It made people argue. The Ministry of Health disagrees with the US. The health minister said the study is paused. This is because of worries. They worry about good rules and science.
The US government paid for the study. Danish people led the study. US people want the study to go on. But Africa CDC agrees with Guinea-Bissau. The Africa CDC director said countries can choose.
Guinea-Bissau had problems before. There was a coup last year. Many leaders changed. The health minister said the science was not good. So, they stopped the study. Africa CDC will send helpers. Danish and US people are also asked.
This shows a big talk about research rules. This is for poorer countries. People want fairness. The US government wants the study to continue. But Africa CDC's words are important.
Stopping the study shows science and country control. Guinea-Bissau decides about this research. Africa CDC helps this idea. More talks will happen. Both sides want to agree. They want good science. This can help health in Africa.
