At that point, I almost think if I had the choice I'd go with the russian one lol.

Potentially less than 60% effective is a huge drop down from 95%.
40%+ of the time it doesn't work, vs 5% of the time.

Russians have given out data on their vaccine, its supposedly decent.
(ei. near as good as european/american versions) (they hacked into tons of labatories, to collect data and research so.... why wouldn't it be?)

I'm mostly basing these suppositions on the method the Russian vaccine uses, that is, a non-replicating adenovirus vector, which makes it similar to the AstraZeneca-Oxford vaccine (which has a ~ 65% efficacy based on the most complete study).

Ideally, I'd still hope CoronaVac works the best out of them, since it's cheap and rollout can proceed rather quickly. And not only to Brazil, for a lot of South American countries have deals to buy dozens of millions of doses from Butantan in the upcoming months. Besides, the method can easily shift between any variant of the virus you want to base it from (and probably SARS-CoV too!).

A few months ago leaked preliminary results claimed CoronaVac was actually the most efficacious vaccine of all those being tested here (this, AZ's, and J&J's), so I'd like to know what went horribly wrong if it landed at 60%. Unless these rumors are bull and it's actually in the 70-80% range or so.

Edit - a point to consider too is the number of people being hospitalized or dying in the control/vaccine groups. If we were only to compare those, the vaccine would probably be significant to virtually all recipients, so it's not like it outright fails to elicit an immune response completely 40% of the time.
