with covid patients, and 93% of them are unvaccinated. and now clay is one of them. >> reporter: you wish you would have taken the vaccine? >> yes. >> reporter: acadia ambulance based in louisiana is the largest privately owned ambulance company in the country. we spent three days with them. dr. chuck bernal is their chief medical officer. of your call volume, how much is dominated by covid patients? >> around 30 to 40% of our calls is covid patients. >> reporter: 27-year-old trent is a field supervisor for acadia. >> we have three of them right now apparently waiting. >> reporter: he took us to lafayette general where ambulances were backed up because no e.r. beds were available. they had to wait with patients 30 minutes to three hours. >> we have to tell the hospital, like, look, find something.

we don't care where you put this patient. you have to put them somewhere because we need to run emergencies. >> reporter: the supervisor is keisha. >> they're all drowning. we're all drowning and sucking air for sure. >> reporter: people will say it's not as bad as you're saying it is. >> i would tell them they might want to come work in e.m.s. come in the e.r., because the nurses feel it. we feel it. >> reporter: this covid surge has also forced acadian to transfer patients out of state. louisiana has a call center in baton rouge that is focused on finding available beds and advanced care for patients around the state. >> all right. y'all can accept? >> reporter: we were there when trauma coordinators david and alison tried finding a bed for an elderly man in central louisiana who had gone into cardiac arrest. there were 15 hospitals within 100 miles, but they told us they could not find a single

available bed. >> they have know beds, no staff to take care of him. that's where we're at today. and that's where we've been. >> okay, so y'all not going to transfer? >> reporter: after two hours looking, la feat says the doctor's told them the patient's condition worsened and he could no longer be transferred. >> he has since gone back into cardiac arrest a couple of times. it's been a roller coaster ride for the family. >> reporter: again, dr. chuck bernal. >> a lot of patients we deem would not probably benefit from the hospital are already being treat in place at home and being left at home. >> reporter: they have not refused to transport anyone yet. >> we're days away from that happening right now much, less than a week. >> reporter: it's the unthinkable. but he has to juggle other priorities, too, like speaking almost daily with medics who are not vaccinated. two of those unvaccinated employees you met at the start of our story. they are the two medics who

transported julia clay, the covid-positive patient, to the hospital. transporting it, you're up close with it. >> right. >> reporter: does that not change your opinion? >> no. i'm very -- me and my family are very religious. we pray a lot. we've always been the type of people that we trust god. >> reporter: are you vaccinated? >> no. should i be? yes, yes, i should be vaccinated. that is very careless of me, you know, because i do come in contact with other people. will i be vaccinated soon? yes. >> reporter: you have more exposure than most anybody else. >> yes. >> reporter: and you still haven't gotten it. >> do i push it? yes, i do. >> reporter: you need pushing in terms of telling other people to do tchlts >> yes, i do. >> reporter: if they were offering it right now, would you take it? >> yes. >> reporter: and it turns out an afternoon with david begnaud convinced her to get vaccinated. here she is getting her first

dose of the pfizer vaccine. in haiti now, there is fear that last weekend's earthquake could turn into a super spreader event. the first batches of vaccines arrived in haiti just three weeks ago and only 1% of the population has been vaccinated. the quake killed at least 2,000 people and left tens of thousands homeless. in some places, roads are destroyed and bridges washed out. vladimir duthiers took a helicopter into the disaster zone. >> reporter: our flight into the quake zone could not prepare us for the destruction down below. once we arrived in lakay, the devastation surrounded us. homes and businesses unrecognizable to those who call this city home. i'm standing atop what used to be a four-story hotel. on saturday when the earthquake struck, multiple people were crushed and killed, including a former haitian senator. and that's the thing about earthquakes. they don't discriminate.

about ten miles from lakay sits a small village of manish where the damage was even more profound. made even worse by the battering rain from tropical depression grace. driving through the town we saw hundreds of villagers outside without a place to call home. this car was completely flattened when this house collapsed, essentially pancaking it. across the street here, this catholic church has stood in manish for over 100 years. it's been utterly destroyed, and now due to the aftershocks, there is a real fear that this tower could come crashing down and hurt more people. for those already injured, help is a world away. we showed you how victims of the earthquake arengerried to hospitals in port-au-prince. here's why. this is what's left of the only hospital in manish. the town's mayor says around 98% of manish was destroyed. they need water and they need

food. and they need assistance with the sanitary conditions. this is exactly what leads to disease. we spoke to a woman whose sister died in the quake. she said many villagers lost hope. she said the focus is on the bigger cities in haiti affected by the earthquake. here in manish no one has paid a lot of attention to them. they feel left behind. they feel as if no one is coming for them. the damage was amplified by tropical depression grace that caused mudslides and rivers to swell. that cut off many remote villages from getting aid and it is unclear when they can receive start your day with crest 3d white and from mochaccinos to merlot, your smile will always be brilliant. crest 3d white brilliance. 100% stain removal, 24 hour stain resistance to lock in your whitest smile.

printers to redesign home building. and so is the future we're going to be out some night seeing hoses? >> this is a complete transformation in the way that we approach sheltering ourselves, and the way we approach building. >> reporter: this newly 5-ton machine follows a computerized blueprint and can build the entire wall system of a home with a concrete mixture in less than a week. it is used for the foundation, roof and plumbing. printing the walls is several times faster than wood framing, and icon says the concrete structures are highly energy efficient and can better withstand natural disasters. so this house has curves. >> that's right. >> reporter: and you don't have to live in a boring box. these wavy 3-d printed walls will eventually become this high-design home. 3-d printed homes are rare, but they're starting to pop up all

over the world. these domes in italy were printed out of dirt in 200 hours. and another company plans to build the first 3-d printed neighborhood in the united states in the california desert near palm springs. so why are they catching on? cost and speed. icon is trying to cut the cost of construction in half while building homes twice as fast, something some housing market experts doubt is possible. but what's not in question is that the u.s. is currently 4 million homes short of buyer demand. >> we need housing for homeless folks. we need affordable starting houses, middle market houses. we need every kind of house period. construction work is hard. this doesn't get tired. >> yes, humans get tired, but humans need jobs. >> there is a nationwide shortage. we're filling a job. >> so this bedroom right here could be a home office, could be a guest bedroom.

>> reporter: paul and his fiancee have been struggling to buy a home in austin's red-hot housing market. >> each of these houses was printed in about a week. >> oh, wow. >> reporter: they came to look at some of the first 3-d printed homes for sale in the country. the first level of this 4 bedroom 4 bathroom house is printed concrete. the second floor is conventional construction. it will be listed for around $700,000. so, would you seriously consider buying something like this? >> absolutely. >> 100%, yeah. >> this is really such a good value in terms of space and the amount of bedrooms. you know, we want to start a family one day. we definitely need extra bedrooms to accommodate that, so. >> settle in. >> reporter: settle in. >> yeah. >> this is the way we should be building. >> reporter: jason ballard is using this technology to shoot for the moon. his company is working with nasa to design 3-d printed shelter for astronauts who could one day live on the moon and mars. >> i think this makes

construction exciting again and it's inspiring and hopeful to have a solution. >> the "cbs overnight news" will be right back.

is doing just that, helping companies to go green by swapping out diesel engines for electric. >> when you're doing the game drive, it feels like you're floating through the grasslands. we like to say safari vehicles are running on sunshine because it's also powered. >> reporter: saving around $150,000 a year in gas bills, that ain't bad either. and switching gears to a greener adventure is getting a warm reception. it seems the animals like it, too. even tourists are feeling the buzz. >> we really share their core values in terms of trying to not disrupt the eco system here and enjoy it, but also be respectful of it. >> reporter: and that's what you want in a safari, to experience the call of the wild without the roar of an engine. >> kwan lee, cbs news. >> and that's the overnight news for this thursday. for some of you the news continues. for others, check back later for "cbs this morning". and follow us online any time at
