A new study about a vaccine is here. It is in a country called Guinea-Bissau. The leaders in the US give money for it. They give about $1.6 million.
The US police have new advice. They say a baby vaccine is a choice. This is new for them. Some people think this is because a man is worried. He is worried about vaccine safety.
Guinea-Bissau is in Africa. Many people there have a sickness. Health experts are worried. They say this study is not good. It is risky.
These are big changes for vaccines. A leader wants these changes. He also stopped money for a group. This group helps children get vaccines. This work saved lives.
Some people think these actions are not fair. They could make people trust the US less. This could hurt global health.
