The study found that people who took two doses of Coronavac, developed by Synovac, get 66% protection against the vaccine while those who received Pfizer-Biontech vaccine get 93% protection.

More than 10 million people in Chile have been vaccinated with Coronavac and 500000 people have received Pfizer-Biontec vaccine doses.

 The final results showed that Coronavac provided 65.9% protection against the virus, prevented 87.8% affected people from hospitalization and 90.3%  ICU admissions. It prevented 86.3% deaths.

In comparison, the Pfizer vaccine is 92.6% effective in preventing the disease, while its efficacy in hospital admissions, IC admissions and death protection is 95.1%, 96.2% and 91%, respectively.

About 14 million Coronavac have been used in Chile since May 10, and more than 6.3 million people have been vaccinated so far.

 In comparison, 2.4 million doses of the Pfizer vaccine have been used.

 Funding for the study was provided by the Chilean National Research and Development Agency.

 It should be noted that this vaccine is also being used in Pakistan along with the Sinophar vaccine and it is being used mostly in young people.

 Pain and swelling at the injection site are the most common of the side effects that people who vaccinated with vaccine. In most people, the effect is mild and disappears within 2 days, while some people experienced fatigue, cholera and muscle weakness during the trials, but the rate was much lower.
