Recently, major schools began to vaccinate COVID-19 vaccine for free, but many students are actually afraid to vaccinate this vaccine. There are many people who have various excuses to refuse. So why are so many people afraid to take this vaccine? I would like to share my personal views with you today. First of all, because you may think that this vaccine has been issued for a short time, there may be some potential dangers that have not been discovered yet, so many students dare not take the vaccine. COVID-19 vaccine is indeed a new invention and discovery for many studies, but because it is a new discovery, many people are more resistant to this vaccine, or secondly, I think many people are afraid to take this vaccine now, largely because they don't know this vaccine very well, because they don't know this vaccine very well, so they will think it is a very strange thing. When this thing is injected into the body, they will feel scared, so they will refuse to take the vaccine, which leads to this phenomenon of not being afraid to fight. Therefore, I think that in the process of popularizing COVID-19 vaccine, colleges and universities should explain the function of this vaccine and its individual precautions to students, so that students can fully understand this vaccine from the bottom of their hearts as the fundamental way to accept it. Finally, some students may eat something they shouldn't eat or do something they shouldn't do after vaccination because of their inner fear, causing discomfort. They will attribute it to the role of the vaccine, so they will tell others, causing others to have fear.
