China not using mRNA

[Onca]

I've had to hold my ground to not take the vaccines offered in the US. Even friends, who I thought would be cautious, ended up getting two doses. If BBC is correct, China is using a more traditional approach, not the mRNA. Who knows? Maybe there's saline solution in the Chinese vaccines, and its citizens will continue to propagate, while ours become sterile.
