@BreakForTheLight, basically it's, as the saying goes here, "es lo que hay" it's what there is. We don't have facilities to manufacture our own and we aren't exactly a world power so I guess they settled with what they could get. Another good saying is "peor es nada", meaning it's better than nothing, which is exactly the reaction of my sister who is a biologist in the US and knows about those things. There's actually a town named that! And, of course "pasar gato por liebre" trying to pass off a cat for a hare, basically promising one thing but giving us another. That's your Chilean Spanish lesson for the day.

My suspicious side thinks there may be more to the situation. It is kind of convenient for our unpopular government. People will still be getting infected, but it sounds like hospitalizations and deaths will be lower. Even so, they may try and use the infection rates to declare quarantines if the protests pick up again.
