Coming up with a vaccine is easy. The time-consuming part is the actual clinical trial, which may take many years. Many side effects of a vaccine may come out months after the injection. Some of them very severe. Vaccines are something that simply cannot be rushed. I strongly hope the Chinese doctors stay calm and don’t act on impulses and/or bend to political and social pressures to rush their vaccines. Otherwise, we will have another vaccine pandemic waiting for us a few months later... this one will be much worse than any Coronavirus can inflict.
There's no need to worry. NMPA has strict protocols for vaccines and it's a highly professional organization. Xi Jinping may have a (IMO extremely unfortunate) fondness of traditional Chinese medicine, but he's certainly not Trump. According to the latest NHC press briefing, when Xi Jinping toured a vaccine development lab on March 2, he stressed that safety must always be the first priority. So no political pressures for speed.
The National Health Commission outlined the status of vaccine developments in yesterday's press briefing:
Inactivated: animal trials, world leading (not surprising as China had access to the actual virus long before other countries did)
Attenuated: animal trials, world leading
Subunit: animal trials, on par with international peers
Recombinant vector: animal trials, on par with international peers
DNA: animal trials, on par with international peers
mRNA: pre-clinical, roughly on par with international peers but may fall behind as China has limited experience here.
