What are the effective rates of the CoronoVac?

The CoronaVac (Sinovac) vaccine was 100% effective in preventing COVID-19 sufferers from being hospitalized or dying. 83.7% effective in avoiding cases that required any medical treatment, but only 50.65-75% effective at keeping people from getting infected.

 

Some people will prefer to get the Pfizer or the AstraZeneca Vaccine due to the higher effective rates as compared to the CoronaVac. There may be some elements that you will need to consider before making your judgment over the efficacy of the different vaccines.

 

I want to put it into context for you to understand the main point! Some of these vaccine-producing companies did their study in developed countries with good sanitary conditions, medical services, social welfare, and lower population density per square (density of people and a living area). These conditions reduce the risk of infection in the population therefore it produces a higher effective rate as compared to CoronaVac.

​

You will notice that CoronaVac's effective rates are inconsistent from country to country:

Brazil 50.4%

Chile 67%

Uruguay 61%

Turkey 91.25%

Indonesia 94%

​

CoronaVac did their studies in the third world, developing, and developed countries. Some of the countries had poor sanitary conditions, medical services, social welfare, and higher population density per square (density of people and a living area). These conditions increase the risk of infection in the population therefore the CoronaVac's effective rate to reduce infection is lower than other COVID vaccines. This does not mean that the CoronaVac is not effective. It appears less effective due to the conditions it was subjected to.

 

At the end of the day, all these vaccines have one thing in common which is 100% rates of hospitalization. Hospitalization means that the disease is severe and all brands of the vaccines have prevented 100% hospitalization.
