It isn't a mistake but rather Sinovac made a strategic decision that the Chinese market is far more important than any other markets
I can't agree here.. There are already hundred-thousands of people using sinovac vaccine in china under EUA, none has any adverse effects, no way that they don't get final approval from the government, it would be a worse disaster by allowing the use of such a widespread vaccine that at the end is not approved. Do you really think the chance of sinovac being accepted by other countries are higher than the domestic approval? You're basically fighting for an imo guaranteed domestic market (as it should be expected to get a preferential treatment for a domestic product, as usual) at the cost of oversea countries where no such preference exists, thus the fight of the market are fiercer. Getting an approval from china also isn't as critical as the other countries either since the virus is pretty much nonexistent.For the Chinese vaccine makers themselves, their biggest battleground is going to be the Chinese market, with 1.4 billion people. If any one of them cuts corners, they can kiss that market good bye. The other vaccine makers will only be all too happy to pick up their share. Furthermore, does anyone think non-Chinese countries will use a Chinese vaccine that isn't even approved in its own country? So the Chinese regulatory approval is the most important consideration for these vaccine makers.
I also personally doubt that these companies can get a better profit by selling it here since I expect the government to force them to sell it marginally close to a breakeven, similar to military products in a sense, so selling 200 million domestically won't be as profitable nor as well-perceived as selling 200 million to multiple countries.
