Centers for Disease Control and Prevention (CDC) says that COVID-19 vaccines are effective. They can keep you from getting and spreading the virus that causes COVID-19. Even if you do get COVID-19, they help keep you from getting seriously ill. However, they are actually still in the clinical trials. Many vaccines take 10 to 15 years to reach the public, but the COVID-19 vaccine has been developed in about a year. “Are we sure they are safe?” “How do we know that they are as effective as we have been told?” In fact, Nobody knows if they are safe. Therefore, I think we should be very careful about vaccination, catching up on the latest data on vaccine ingredients, efficacy, and side effects. I’m a little bit worried that there are some people who don’t research the vaccines and believe that they are totally good. Furthermore, I’ve heard a story that a person who did not want to get a Covid-19 vaccine did so anyway because of pressure from her peers and her employer. This is what should not happen. While no one can say that the vaccines are absolutely safe, it is wrong to force others to get them. Each person should have the freedom to get them or not.
