Emma: We are seeing a bigger drop of cases in countries that are using more Messenger RNA vaccines for Pfizer Biontech, Moderna. Are you concern about a disparity developing between the part of the world that are using your vaccines and less effective vaccines and part of the world that are using MRNA vaccines?
Yin: While it is hard to reach 100% vaccination rate even when you have the vaccines, the next key consideration is safety, vaccine safety has a great impact on vaccination rate for a massive population, if a vaccine has severe side effects even it's just very rare, it will hurt people willingness for vaccine overall.
Yin: We have seen some countries which have already recieved huge amount of vaccines and have reached high vaccination coverage and they all have well-established cold chain system, which is not accessible for many countries in the world. What we are facing is a global pandemic not just an outbreak in one country, efficacy varied among different vaccines, but I want to emphasize "A goal is not to compared whose efficacy is high or low, but who can bring cases down in this country this region or this city. That's our ultimate goal.
Emma: I understand that though, I do think the different efficacy rate for different efficacy rate has potentially led to some hestitation, in some of those countries, around corona vac, because as you said yourself earlier there are such a high level of scrutiny on these vaccines higher than any vaccines that ever been made really with the public knowing much more about them than they would about the ordinary Flu vaccines or other vaccines that they are taking. What's your response to that?
Yin: We will do more study on protection rate, but the efficacy shown in phase 3 trial can't truly represent the protection following vaccination. We have seen the effectiveness from Chile real world study is higher than the efficacy in phase 3 trial. So at the end of the day everybody will look to the reduction in cases in your country as the most important protection rate.
Yin: It wouldn't be that different. In an emergency situation doing the most important thing will alway be our top priority. When Covid break out the priority has to be meeting the huge vaccines demand from different countries even if we were in the similiar situation in the future we still make such trade off wheter we get the paper out first or wheter we should get the vaccine registered first.
Emma: What do you think this global vaccines roll out says about China's nascent pharmaceutical industry and it's future and what do that you think is the main differences that you've seen between the way Chinese company's had approached this vaccine development and roll out.
Yin: So far, we had provided three hundred million doses globally, Sinovac now has a capacity to manufacture 2 billion doses of vaccine in Beijing, our monthly production could reach over 200 million doses or even 300 million doses, thus speak the level of China vaccine industry.
