After each crisis, solutions are always postulated to prevent it from happening again. After a pandemic or epidemic, there are different opinions about possible solutions, and in the past, a new vaccine has been seen as an answer. A vaccine is a substance that is introduced into a body to trigger the body's defensive reactions, especially the formation of antibodies. Vaccines are made and developed in laboratories, so they can test possible solutions. But there are conflicting views on whether or not to get vaccinated. There is concern about what these vaccines really contain, and whether it is wise to let yourself have a new substance injected  into the body. Especially in such a short time, it is difficult to know what all the adverse side effects to the vaccine could be.  An educational  campaign about prevention can be followed by this future solution, which may or may not be effective. We will see if it also brings more problems. The best preventive campaign is Prevention itself, to counteract the spread of the virus. It is simple sanitary measures that every human being on the planet can fulfill. This includes things such as social distancing and washing hands, not touching one's face and staying healthy enough to have an immune system with high defense. Not to mention that this system would be more economical. Which makes it possible for the entire world population since vaccines would have economic costs that have not been measured on a global scale. “TAKE CARE OF YOURSELF. Keep your body clean. You are well within your rights to insist that people bathe regularly and wash their hands. It is inevitable that one gets dirty working or exercising.” L. Ron Hubbard. www.thewaytohappiness.org @waytohappinesstampa
