I remember having seen a video from WHO or USAID yata na ang gist is wag daw tignan yung % efficiency kasi irrelevant daw yun. Absent cost considerations I'd totally agree to its premise, pero kung isasama na yung cost implications, parang impractical na ipilit yung Sinovac 1/n https://twitter.com/ABSCBNNews/status/1381445719647719428

Kasi diba, isa sa mga pinakamahal na bakuna yun? Tapos bibili ang Pilipinas nun, na 50% lang pala ang chance na magwork siya? Paano yung other 50% na hindi tatablan, edi parang nagsunog lang tayo ng pera? Ganun ba tayo kayaman? Ganun ba kalakas ang healthcare system natin? 2/n

And take note na hindi pa pumapasok sa usapin na ito yung absent na published, peer-reviewed phase 3 clinical trial results nung bakuna. Haaay araw-araw may nakikita talaga akong mali. Minsan tinatanong ko na sarili ko, ako lang ba to? Sadyang negative lang ba akong mag-isip? 3/n

O talagang napakapabaya, inutil, clueless, at corrupt lang talaga ng mga namamahala at nagpapatupad ng ating pandemic response? Parang sobrang liit ng margin of error natin para maging slacker. Hanggang ngayon walang sense of urgency, slacker pa rin! Lagpas 1 year na!! [end rant]

Here's the video I was referring to, it's by Vox pala:

It seems na mali pala yung naalala kong meaning ng efficacy rate. Will have to review and revisit the arguments I presented in this thread. But this supports what you pointed out earlier @spajettie
