COVID-19 is an infectious disease with a high proliferating ratio. The global population has been vulnerable to this disease ever since it started infecting people in the city of Wuhan in 2019. Despite advanced scientific technology, it took almost a year for pharmaceutical companies to come up with a vaccine for this pandemic. After a year of checks and trials of different vaccines, several brands made it into the market. The first round of vaccines included the release of Moderna and Pfizer-N-BioTech, followed by Sinopharm in China and Sputnik in Russia. The effectiveness of these vaccines varies as some vaccines like Moderna and Pfizer have a higher efficacy ratio than Sinopharm and AstraZeneca. However, most of these vaccines are acceptable for consumption because a single vaccine can not be provided across the globe, which calls for the production of more locally produced vaccines.
