it was kind of rushed onto the market, so the data is still coming in. the head of the covid response team here at the white house says these relapse cases are rare, in the single digits but the good news is even if you rebound most of these cases are mild, 90% of people who take this stay out of the hospital. the president is not going back on the medication. he's just going to isolate and wait until he gets another negative covid test. adriana. >> christina ruffini, thank you so much. now, to flood ravaged kentucky. the death toll rose again today. at least 25 people have been killed. and rain is again forecast for this weekend, as rescue crews struggle to get to the hardest hit areas swamped by what's described as the worst flooding to hit the region in decades. we get more now from cbs' tom wait. >> reporter: kentucky is racing to recover as receding floodwaters reveal the scope of devastation in the state's hard struck appalachian region. entire communities were wiped out in the catastrophe. >> lives were destroyed.

to cover up its torture of ukrainian prisoners of war and it's demanding a u.n. investigation. but russia's claiming the ukrainian military killed its own soldiers with american-supplied rockets. also in eastern ukraine, more senseless civilian casualties, more families struck down by grief. in ukraine's second city, kharkiv, a russian missile targeted this park, a place where children once played in safety. even ukraine's youngest citizens are being slaughtered in russia's vicious invasion. a 12-year-old girl decapitated by shelling. a 13-year-old boy killed as he waited for a bus. the city of dnipro is around 100 miles from the front line, and up until now it stayed

relatively calm. in its park, life looks normal enough. but nearly everyone here has a war story, including 9-year-old oleksander. he fled the fighting in kharkiv with his family. he told me how they hid in a basement with enemy planes overhead and explosions outside. ukraine used to be a peaceful place, now russia's plunged it into a nightmare. and children have no immunity from the violence. holly williams, cbs news, dnipro, ukraine. the last patient wounded in the school massacre in uvalde, texas, has left the hospital. 10-year-old mayah zamora passed out roses to staff as she walked out of a san antonio hospital on friday. she arrived in critical condition and spent 66 days recovering from multiple gunshot wounds. hospital staff called mayah their hero. to georgia now where investigators have released body cam video of a woman who died

administer vaccines which is crucial. health officials say time is of the essence to get this outbreak under control. after three visits to the er, david watson has a warning for people who take monkeypox lightly. >> it is the most painful thing i have ever experienced in my 47 years on this planet, and i wouldn't wish it on my worst enemy. >> reporter: right now the demand for the vaccine is outpacing supply. many are finding it difficult to get an appointment for a shot. >> i have been asking for a vaccine since the middle of june. >> reporter: the federal government is in the process of distributing more than 780,000 doses. but it's not fast enough in pl places like new york and san francisco. >> we are at a very scary place and we don't want to be ignored by the federal government in our need. >> reporter: stanford university's dr. jorge salinas says the biggest challenge now

is getting the doses we have where they're needed. >> the longer we take to vaccinate the at-risk population the more it will spread. >> reporter: the monkeypox virus is disproportionately affecting men who have sex with men, but anyone can catch it. it's spread by skin on skin contact, and it's rarely fatal. >> our public, our population needs to continue following public health recommendations, practice safe sex, get vaccinated as soon as a dose is available to you. >> reporter: and there are also calls for the biden administration to declare monkeypox a federal health emergency. that would free up more resources and funds to fight the outbreak. adriana? >> all right, michael george, in a noisy new york city, thank you. tonight, pope francis is back at the vatican after his trip to canada. speaking to reporters on the flight across the atlantic, the 85-year-old said the fast-paced six-day visit was also a test of his endurance, mentioning the possibility of one day stepping aside. and for the first time, francis called the church abuse of canada's indigenous people genocide.

cbs' chris livesay was traveling with the pontiff. >> reporter: pope francis humbled by the sacred rituals the catholic church once tried to suppress. [ speaking foreign language ] "i've come to beg for forgiveness," he said, forgiveness for catholic run boarding schools. children were ripped from their homes, stripped of their identity, and forced to be christian. their hair was cut, their ancient traditions banned, and speaking their own language was a punishable offense, often with violence. closed in the 1990s, more than 150,000 children later. as far away as the inuit village just south of the arctic circle survivors turned out to hear the pope. [ speaking foreign language ] "i want to tell you how very sorry i am," he said, even apologizing for priest sex abuse, once rampant in canada's

residential schools. and now after so much trauma, the time has finally come to forgive says phil fontaine, the former chief of the national assembly of first nations and a survivor of boarding school abuse credited with first bringing this issue to international attention. >> the holy father in a very humble way begged for forgiveness. if forgiveness is absent, we will drag this out forever. and our people don't deserve this. >> reporter: francis seemed to receive that forgiveness in one unforgettable ceremony, a ritual and a people that despite the church's best efforts could not be erased. says first nation's veteran chief david gamble. >> we're taking back our language. we're taking back our culture. we're taking back our traditions. we have our own schools on the reserve. we're doing things for ourselves now. >> reporter: generations of

trauma and not just in canada. there were once more than 400 such schools in the united states as well. now, aboard the papal plane that just returned to rome, pope francis told us what happened at these schools was nothing short of cultural genocide. chris livesay, cbs news, rome. well, someone in illinois hit the mega millions jackpot and it wasn't me. the winning ticket was sold at this speedway in des plaines, illinois, a chicago suburb. the jackpot ballooned to more than $1.3 billion after no one matched all six numbers since mid-april. but don't toss your ticket just yet. 26 were sold matching enough numbers to win $1 million. and straight ahead on the cbs weekend news, tenants face a storm of rising rents with prices surging through the roof. and a chicago store helping all kids find their power on every page. for copd, ask your doctor about breztri. breztri gives you better breathing,
