Preliminary data indicate that the vaccine developed by Sinovac prevents 57% of disease cases and Pfizer’s vaccine, 75%.

In relation to admissions in Intensive Care Units (ICU), the Chinese immunizing agent prevents 95% of admissions and the US pharmaceutical vaccine, 99%.

Of all people vaccinated with CoronaVac in the country (712,716 individuals), 5,360 tested positive for Covid-19 after more than 14 days of completion of the vaccination schedule. Of this number, 19 people required admission to the ICU and six died. In the case of Pfizer, 149,329 Uruguayans received the immunizing agent and 691 of them tested positive for the disease within a period of more than 14 days after the second dose. Of those who were PCR positive, one required admission to the ICU and a total of eight people died. All belonged to the age group of 80 and over.
