Indian regional health minister tests positive for Covid-19

The novel coronavirus has infected more than 19.8 million people worldwide and caused more than 731,570 deaths. Here's what you need to know:

Contrary to his predictions, President Trump won’t have a coronavirus vaccine ready by Election Day, vaccine experts tell CNN after reviewing data from Moderna, the first company to begin Phase 3 clinical trials of a coronavirus vaccine in the United States.

Last week President Trump said he was "optimistic" a vaccine would be ready around Election Day on November 3.

"I believe we'll have the vaccine before the end of the year, certainly, but around that date, yes. I think so," Trump said Thursday.

CNN obtained part of an email Moderna sent on Friday to the principal investigators of its vaccine trials. It says 4,536 study subjects have enrolled in the trials.

The trial started on July 27, and intends to enroll 30,000 study subjects. The company has said it is "on track to complete enrollment in September."

Moderna won't make that 30,000 in September if they continue at the rate of the first two weeks, but it’s likely the speed of enrollment will ramp up, since as of Friday only 54 of the study's 89 sites were operating, according to the company's email to its researchers.

Moderna's numbers did increase significantly from the first week of the trial to the second week.

Even if Moderna does reach its goal of full enrollment during the month of September, the company still won't have a vaccine on the market by Election Day, infectious disease experts say.

After Moderna enrolls its subjects and gives them their first shot, they then have to wait 28 days before giving them a second shot.

That means participants enrolled at the end of September won’t be getting their second injections until the end of October.

Offit said they then have to wait two weeks for the vaccine to become fully effective.

"That takes you past Election Day," Offit said.

After that, the researchers have to wait and see who gets sick with Covid-19 and who does not. Half the study participants are receiving the real vaccine, and half get a placebo, or a shot that does nothing. Neither the participants nor the doctors giving the vaccines know who got which injections.

Both Offit and Hotez predict there will be results from the Moderna study in the first quarter of 2021 at the earliest.

UK Prime Minister Boris Johnson says the UK has a "moral duty" to reopen schools full-time next month for children's wellbeing.

Schools in England closed in March, though many remained partially open for vulnerable children and the children of key workers.

Some pupils in kindergarten, grade 1 and grade 6 went back to school in June.

Johnson visited schools in East London on Monday.

Johnson's comments come after he wrote an article for British newspaper the Mail on Sunday, declaring school reopening a "national priority."

He said children were at increased risk of domestic violence, exploitation and addiction if they remained out of school for any longer than necessary.

Johnson has repeatedly said that the risk of children becoming severely ill from coronavirus is “low," but safely reopening schools remains a fraught process for officials.

A key member of the group advising the government on its Covid-19 response said last week that the UK may need to choose between keeping pubs open or allowing schools to reopen, if it wants to keep coronavirus infection rates down.

When Kim Reeder started teaching in Parker, Colorado, 14 years ago, she found that managing the classroom environment took way more time and energy than actually teaching children, and she couldn't reach as many of them as she wanted.

Then Reeder discovered virtual school. As a middle school social studies teacher at Colorado Connections Academy for the past 13 years, she's found that "there's really no classroom management."

Online teaching at the academy, a public school for children from kindergarten through to 12th grade, gives her the time, freedom and energy to "give every student what they need."

Many schools around the world abruptly transitioned to distance learning in March, when Covid-19 forced brick-and-mortar schools to shut.

But much of what students have experienced since then didn't represent real online schooling, in which teachers are trained to teach remotely and online.

Every day, the US is reminded of Covid-19's ongoing impact as new death counts are published. What is not well documented is the pandemic's toll on the family members of those whose lives are lost to the virus.

New research suggests that damage is enormous: For every person who dies of Covid-19, nine close family members are affected, researchers estimate -- based on complex demographic calculations and data about the coronavirus.

Many survivors will be shaken by the circumstances under which their loved ones pass away — rapid declines, sudden deaths and an inability to be there at the end — and worrisome ripple effects may linger for years, researchers warn.

If 190,000 Americans die from Covid-19 complications by the end of August, as some models suggest, 1.7 million Americans will be grieving close family members, according to the study. Most likely to perish are grandparents, followed by parents, siblings, spouses and children.

The 50-year reign of an Australia-based micronation formed by a "prince" has come to an end.

Hutt River, a self-declared principality, issued its own passports and once even declared war on Australia. In recent years, however, it's been known as a quirky tourist attraction.

But the economic impact of the Covid-19 pandemic, coupled with a giant tax bill, have forced the principality to announce it will finally "surrender" to Australia.

Hutt River's origins as a micronation date back to 1970, when the late Prince Leonard Casley claimed he'd exploited a legal loophole to create the principality in an isolated part of Western Australia, 500 kilometers (310 miles) north of the state capital, Perth.

Set on 75 square kilometers of farming land, it was more than twice the size of Macau, but populated by fewer than 30 people.

Former Indian president Pranab Mukherjee has tested positive for coronavirus,

"On a visit to the hospital for a separate procedure, I have tested positive for Covid-19 today," Mukherjee wrote in a post on his official Twitter account Monday.

"I request the people who came in contact with me in the last week, to please self isolate and get tested for Covid-19."

Mukherjee served as India's president from 2012 to 2017, following a career during which he held a string of prominent government roles.

India's Minister of Home Affairs Amit Shah announced on August 2 that he had tested positive for the virus and B.S. Yediyurappa, the chief minister of India's southern state of Karnataka, announced his positive diagnosis on the same day.

India has more than 2.2 million recorded cases of the virus, and 44,386 deaths, according to Johns Hopkins University.

Leaders from US college sports' "Power Five" conferences discussed postponing the country's football season and other fall sports over the weekend amid the coronavirus pandemic, according to reports from multiple sports news outlets including ESPN, Sports Illustrated and CBS Sports, who all cited several sources.

No decision has been reached yet, and the discussions are expected to continue over the next few days.

"It's an ongoing conversation we've been having for weeks," Big 12 commissioner Bob Bowlsby told CBS Sports on Sunday night. "We talk almost every day. I'm not aware decisions have been made."

The discussion took place in the same weekend the US crossed 5 million cases of the virus. At least 5,044,864 people have tested positive and 162,938 have died as of Monday morning, according to data collected by Johns Hopkins University.

Greece recorded its highest ever daily tally of Covid-19 cases on Sunday.

The country reported 203 new cases, most of which are in its two largest cities -- Athens and Thessaloniki. Twenty-two patients in Greece are intubated, up from 14 on Friday.

The Greek government is expected to announce new pandemic measures this week amid the rising numbers.

Greece had previously managed to keep its case count low by enforcing a strict and early lockdown.

The country reopened its borders to tourists from the European Union and a handful of other nations on July 1.

Greece has so far recorded 5,623 coronavirus cases and 212 deaths, according to Johns Hopkins University.
