the chart shows the Worldwide distribution of vaccines

The pie chart compares the proportional of usage of vaccines worldwide. The line graph, however, illustrates the distribution of vaccine coverage in six countries from December 2020 to April 2021. Overall, the number of inoculation against Covid 19 was on the upward path. It is apparently that vaccinations’ rate was reigned over by China, whereas Germany and Brazil’s figures were reported to be the lowest one. Among the vaccines approved, while AstraZeneca was the most popular choice, CanSino, Covaxin, EpiVacCorona, Johnson & Johnson, Sinopharm, Sinovac, and Sputnik V appeared to be the least preferable. According to the sector graph, AstraZeneca was the predominant mode, which accounted for 37, 9% vaccinations’ proportion, followed by Pfizer with 25% of the rollout. The third highest shares were prevailed over by Moderna and Sinopharm at 10. 4% and 9. 8%, respectively, whereas alternatives accounted for over a quarter. From December 2020 to January 2021, the number of doses administered in China and the United States just reached 1 million. Meanwhile, it took India 3 moths to reach that exact ratio. Over the next month, after a slight fall of 1, 2 million, it is the most striking feature that China’s proportion rocketed to the peak of over 5 million vaccinations, but quickly bounced back to roughly 4 million at the end of the given period. In the final months, while the United States experienced a significant growth to above 3 million, India soared to the highest point of just under 4 million, followed by a gradual drop to approximately 2, 2 millions in April. The UK, Brazil and Germany, on the other hand, stabilized at under 1 million till the end of the period.
