The term has many meanings, from the wild animals it attracts to the trees and shrubs it grows on to the birds and mammals it helps protect.
But it’s usually used to describe an animal or plant that can be harmed by the vaccine.
The flu vaccine can’t harm animals or plants, but it can harm people and pets.
Here are some of the things you need to know about flu vaccines.

The flu vaccines are also made from two other chemicals.
Two of these are a protein that helps keep the virus alive, and a hormone called TNF that helps the body fight infection.
This term can also refer to natural substances such as soil or the earth’s minerals.
Examples are coral, seaweeds, and sand.
This means “designed to be produced in a way that can’t be changed.”
