Human beings are members of a whole / In creation of one essence and soul / If one member is afflicted with pain / Other members uneasy will remain / If you have no sympathy for human pain / The name of Human you cannot retain. Corona pandemic reminded us how the outbreak of an infectious disease can be fatal. At the moment vaccines are the only hope to normal life. In fact, covid is not the first disease to be confronted by vaccines and earlier, there were multiple diseases to be controlled by vaccination method. Smallpox, for example, has killed more than 300 million people or infantile paralyses whose victims were mostly little children. In addition, measles still kills more than 150,000 people a year although the vaccine was developed in 196. That why people around the world must unite for global vaccination, so that they can embrace their love ones without fear. Hopefully one day Covid will be eradicated with the help of universal vaccination.
