I've been asking around again, and what people say seems to be that now things are very similar to how things are in Mexico. I mean, supposedly, they are asking for certificates and things like that, but people don't really care much. Not that they are against it necessarily, but most just don't care.
You see, in that regard, Latin American countries are in general like that. Some places have to abide by the rules more than others but most won't do it not because they are against the rules but because they would lose clients if they enforce the rules too much. Informal economy is also big in Latin America, so if you don't work for a company, you may be better off. At least companies can still choose whether or not to require vaccination. I would guess that even they approve the "Health Pass" project, some places will enforce it while others just won't care about it.
A friend that goes to the countryside a lot told me that in some places you see people in the streets with masks, just like in the city, and in the city you see people wearing masks just under the nose, so it isn't really that people are freaking out or anything. You can't go to the supermarket without a mask (at least in Asuncion) they tell me, but that's not much a nuisance compared to other measures.
Some events ask for certificates, some schools do it too, and some jobs too. That's a fact, because most of the people I talk to have children and work, and they have personal stories of how they or others they know were asked for vaccination for their jobs, or children being asked for vaccination in order to get to school. It is controversial because there are some parents who don't want to vaccinate their children, but according to the people I've been asking around, these are few, not too many.
Other friends who are more into economic analysis and things like that tell me that the economy is crumbling, but that's happening everywhere too.
My perception is that, you'll be quite OK if you don't have to work for a company there and if you don't have children, because it seems that right now, the pressure is more on the people who work for big companies and on schools, which is sad. I still work for an Educational institution in Paraguay and I talk to teachers, so I hear stories from them too. Most got vaccinated.
The thing is that, Paraguay has been through periods of lockdowns which hasn't been the case where I live now and that's why I have the impression that things were quite more strict over there for some time at least. It seems that it is also why people seem to be fed up with rules and they tell me they just won't take another lockdown. Also, it seems that worldwide, countries are lifting the restrictions for whatever reason, so, they certainly wouldn't last much longer in Paraguay. The fear seems to be fading. As for whatever comes next, again there's no way to know for sure how things will be in any place. So, I guess that if you feel like jumping into that adventure it won't be too different from other places in the world regarding COVID restrictions, vaccines and so on, I suppose.
