Covid-19 is a virus that has been spreading quickly around the world. To help protect us from getting sick, doctors and scientists have made a vaccine, which is medicine that can help make us stronger and better able to fight the virus if we get it. Unfortunately, some people have been spreading false stories about the vaccine, saying things like it isn't safe or it can cause bad side effects. This is called misinformation. Meanwhile, some people are hesitant to get the vaccine because they are scared or uncertain of the effects. That is called hesitancy. It is important to talk to a doctor or health expert to get correct information and to help make a decision that is right for you.
