A Sinovac representative told CNN that the discrepancy in efficacy results was due to the different situations in countries where clinical trials were carried out.
"The results are from different populations, in different places with different morbidity rates, and therefore they span a relatively large range," the representative said.

And efficacy might not necessarily mean how effective the vaccine turns out to be. "Once the vaccine moves from clinical trials into the community, you need to think broadly about all the different aspects of what makes a vaccine work," Turner said.

Experts have said that while scientific discussion of new data being made available is a good thing, it shouldn't detract from the fact that all vaccines that have been approved in countries around the world have been shown to be safe and effective at stopping death and serious disease.

The main thing is we want to stop deaths, that's the first thing you want. If you vaccinate as many as you can, you know the vaccine may not stop all people from getting infected but those are good at stopping serious infections, hospitalizations and death. Time is not on our side.

Mexico announced a huge bet on Chinese vaccines Tuesday, without making public any information about their efficacy.

Foreign Relations Secretary Marcelo Ebrard said the Mexican government has signed agreements for 12 million doses of the yet-unapproved Sinopharm vaccine and increased to a total of 20 million doses its contracts for the Coronavac dose made by China’s Sinovac.

However, Ebrard’s office has repeatedly refused to answer questions about the efficacy of the Chinese shots.

Sinopharm has claimed its vaccine was 79% effective based on interim data from clinical trials, but like other Chinese firms, it has not publicly released its late-stage clinical trial data.

Experts in Hong Kong have assessed the efficacy of the Sinovac vaccine at about 51%. That shot has already been approved for use in Mexico.

The CanSino vaccine has been approved in Mexico and reportedly has an efficacy rate of around 65.7%,

Amid a dearth of public data on China’s vaccines, hesitations over their efficacy and safety are still pervasive in the countries depending on them.

Inoculations with Chinese vaccines already have begun in more than 25 countries. None of China’s three vaccine candidates used globally have publicly released their late-stage clinical trial data.

They are into space technology and engineering, as well as, other scientific and educational advances but they are not a perfect society.... nowhere is.  The US and all other countries have some sort of defects, like poverty, racism, police misbehavior, poor infrastructure, lack of good affordable health care for everyone, and on and on.

Let he/she/the country without sin cast the first stone.
