Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
A clinic administered the covid vaccine to 650 people. 80% of the people were adults. How many of the vaccinated people were children?

### Response:
Since 80% of the people were adults, this means 100% - 80% = 20% of the people were children.
20% of the people vaccinated were children, which is 20/100 * 650 people = <<20/100*650=130>>130 people.
