And with the return to school, the Delta variant on the rise and winter approaching, health officials are concerned it could get worse. On Monday, the US Food and Drug Administration (FDA) gave full approval to Pfizer's vaccine for people aged 16 and older. Approval for youths aged 12 to 15 is expected to follow soon.    In the UK, infections dropped when the summer vacation began in July and fears are growing that figures will explode once again when schools reopen in September. There are no mask mandates in classrooms and while the UK medicines watchdog has approved the Pfizer and Moderna shots for children and teenagers aged 12 and above, only clinically vulnerable teenagers have been able to get them so far. The government said Sunday that 16- and 17-year-olds will be offered the vaccine by next week, but there has been no announcement on the inoculation of younger children.     Two studies released this week suggested waning immunity from Covid-19 vaccines but stressed that the shots still provide high levels of protection against severe disease for most of the population. The US Centers for Disease Control and Prevention (CDC) found that vaccine efficacy at preventing infection dropped from 91% to 66% once the Delta variant accounted for most of the circulating virus. UK researchers found that protection decreased slightly after six months among people with two doses of the Pfizer/BioNTech or the Oxford/AstraZeneca vaccines. The worry is that people who were vaccinated around six months ago could be at an increased risk of Covid-19, lending further evidence for booster shots in the fall.    The news comes as the US's top infectious diseases expert, Dr. Anthony Fauci, said the pandemic will not be under control until the spring of next year -- and even that timeframe would need most American vaccine skeptics to change their minds. Despite mounting studies showing the benefits of vaccination, tens of millions of Americans are hesitant to get the shots.     The World Health Organization (WHO) said this week that Covid-19 cases appear to be plateauing globally after increasing for nearly two months. The Western Pacific and the Americas saw the largest increase in cases last week, the former partially driven by the widening Delta outbreak in Australia. Over the past week, the country's single-day caseload has repeatedly reached new highs, surpassing its previous record from August last year.     The merits of the zero-Covid strategy followed by many Asia-Pacific countries have come into question amid this regional rise in cases. Australian Prime Minister Scott Morrison hinted at an end to the country's zero-Covid strategy in an opinion piece published Sunday, warning Australians to expect a rise in infections as restrictions ease. New Zealand authorities reported 62 new locally transmitted Covid-19 cases Wednesday -- the highest number in a single day. However, China reported no new cases on Monday for the first time since July, as authorities double down on their stringent zero-Covid approach.  THE LATEST NUMBERS Global Cases 213,346,591   Global Deaths 4,455,549 US Cases  38,077,523   US Deaths 630,838  Source: Johns Hopkins University YOU ASKED. WE ANSWERED. Q If one person in the household gets a breakthrough infection, should everyone get tested? A Yes, says CNN Medical Analyst Dr. Leana Wen. Close contacts should all be tested, with "close contact" defined as being within 6 feet for a total of at least 15 minutes over a 24-hour period during the potentially contagious period, she added.    The CDC differentiates guidance for those who are vaccinated versus those who are not. Those unvaccinated, if exposed to a close contact who has Covid-19, should quarantine for 10 days. They can shorten the quarantine to seven days if they have a negative test at least five days after exposure. During that quarantine period, they cannot go out in public.    On the other hand, those fully vaccinated, when exposed to a close contact who has Covid-19, do not need to quarantine unless they develop symptoms. They should still get tested within three to five days after exposure and wear a mask in public for extra protection.    Send your questions here. Are you a health care worker fighting Covid-19?

TOP 3 READS OF THE WEEK   Report into the origins of Covid-19 may be released this week    US President Joe Biden was briefed on the findings of a report into the origins of Covid-19 on Tuesday, two administration officials told CNN. The report could be released to the public as early as this week. However, all the agencies in the intelligence community had low confidence in both of the Covid-19 origin theories -- a lab accident or natural emergence -- and were switching sides as recently as Friday, a source familiar with the process told CNN.     While the report is not expected to be groundbreaking, Asian American leaders are worried that its release will be used to "legitimize racist language" and lead to more anti-Asian violence across the country.   Kenya's coffin makers have struggled to keep up with demand in the pandemic. Credit: CNN   Kenya's coffin makers say Covid means they're busier than ever. Some still won't get vaccinated    Kenya has struggled with vaccine supply, and so far only 3.6 million doses of vaccine have arrived in in the country. But as supply issues slowly ease, vaccine hesitancy is quickly emerging as a serious problem, Scott McLean and Idris Mukhtar report.    This is playing out in Kenya's hospitals as a fourth wave fueled by the Delta variant sweeps the East African nation. Many hospitals are turning away new patients as they do not have enough room. And at Mount Kenya Hospital, most patients are unvaccinated -- not because they didn't have access to a vaccine, but because, in most cases, they chose not to take it.  Right-wing media pushed a deworming drug to treat Covid-19 that the FDA says is unsafe for humans    US public health officials are aggressively dispelling claims by right-wing media personalities who have been promoting an anti-parasitic drug used for livestock as a potential Covid-19 treatment, Oliver Darcy reports.     "You are not a horse. You are not a cow," the FDA tweeted Saturday about ivermectin. "Seriously, y'all. Stop it."    TODAY'S TOP TIP Millions of students are heading back to school with a challenge they didn't need to face last year. The more contagious Delta variant is powering a Covid-19 surge in the US that's sending younger people to hospitals -- including children. The best weapon for students aged 12 upwards is vaccination, the CDC says. But there are also ways to help kids too young to get vaccinated dodge Delta.    Here's how students can stay healthy before, during and after school.
