Abstract

By the end of year 2019, All over the world have known new diseases that had begun to spread from Wuhan city of China and become global pandemic affecting.  World Health Organization (WHO) had declared COVID-19 as a global health emergency on January 30, 2020 and characterized it pandemic on 11 March 2020. Within 14 months after the first case have reported in Wuhan The coronavirus COVID-19 is spread across 219 countries and territories affecting more than 126 million people worldwide and resulted in about 2.77 million deaths (~ 3% mortality rate)¹. Needless to say, COVID-19 has become the most serious public health crisis of our generation and has a profound impact on the global economy and geopolitics

 Many drugs were invented and many measures for disease control had failed to stop the outbreak. Considering the rapid spread and high mortality of COVID-19, an effective vaccine is urgently needed and hoped to control this pandemic. Many researchers all over the world were race against time to develop the most efficiency vaccine against COVID-19 in the shortest times. To date the development of a new vaccine has been a long process that typically takes anywhere from 10 to 15 years. Hence, it is clearly a challenge to develop a vaccine against COVID-19 in a span of 12–24 months. Many of the vaccine platforms that complete phase 3 trial had announced their result of estimated vaccine efficacy above 70% and demonstration the safety efficacy to get approval. 

Although the demand for a vaccine far surpasses the production capacity, it will be beneficial to have a limited number of vaccines available for the more vulnerable population by the end of 2020 and for the rest of the global population by the end of 2021.
