New Zealand closes off all retirement homes after new coronavirus cases emerge
From CNN's Isaac Yee
All retirement homes in New Zealand will be closed off in a bid to protect “vulnerable ” communities from the spread of coronavirus, Prime Minister Jacinda Ardern announced at a news conference Wednesday.
Ardern said all aged care facilities would be closed to everyone but staff and essential deliveries from noon local time Wednesday.
“I realize how incredibly difficult this will be for those who have loved ones living in these facilities but it is the strongest way that we can protect and look after them,” Ardern said.
All four of the cases were found within one household in South Auckland, and none of them had recently traveled outside of New Zealand, according to New Zealand's Director-General of Health Dr. Ashley Bloomfield.
Elections in doubt: Ardern also announced Wednesday that New Zealand would defer the dissolution of Parliament "by at least a few days," which would allow it to reconvene if needed.
The dissolution of Parliament was scheduled to take place on Wednesday in a key step toward holding a national election on September 19.
Ardern said that “no decision yet as you can imagine” has been taken regarding the postponement of the election.
Mass testing: Speaking at the same news conference, Bloomfield said health officials have prepared “to test tens of thousands of people in the coming days, so we can see if there are anymore cases of Covid-19 in the community.”
He added that New Zealand has over 270,000 coronavirus tests in stock, with the ability to process 12,000 tests per day.
Back into lockdown: Auckland, the most populous city in New Zealand, was placed under level 3 restrictions following the confirmation of the new cases Tuesday. All non-essential businesses, including restaurants and bars, are closed, and residents are only allowed to leave home for essential activities such as grocery shopping. Schools in Auckland will also be closed for three days.
The rest of New Zealand went into level 2 restrictions, where businesses can remain open as long as they follow public health guidelines.

"I've taken it myself": Russian CEO says he has administered Covid-19 vaccine to his family
From CNN's Leinz Vales
Kirill Dmitriev, head of the Russian Direct Investment Fund (RDIF), which is funding the coronavirus vaccine research approved in Russia said Tuesday the rollout of the drug "will be very gradual."
"We're not going to give it to 10 million people tomorrow," Dmitriev told CNN's Anderson Cooper and Dr. Sanjay Gupta. "It's going to be a very gradual, careful rollout going forward."
Developed by the Moscow-based Gamaleya Institute, the vaccine has been named Sputnik-V, a reference to the surprise 1957 launch of the world's first satellite by the Soviet Union. It has yet to go through crucial Phase 3 trials where it would be administered to thousands of people.
"We can say that it works," Dmitirev told Gupta. "I've taken it myself. I've given it to my parents, to my wife."
The World Health Organization said in a statement about the Russian vaccine that "accelerating vaccine research should be done following established processes through every step of development to ensure that any vaccines that eventually go into production are both safe and effective."
Cooper asked Dmitriev, "To those who are saying that this vaccine was rushed. You said it was proven. How has it been proven effective?"
"It's been proven through phase one, phase two trial," Dmitriev said. "We will have phase three trials in many other countries, in the UAE, Saudi Arabia, Brazil and Philippines." "According to Russian law, when you have a pandemic, when you have epidemia like this, you can do phase three concurrently with launching to high-risk groups, which we are doing. We believe that's exactly the right approach, and this approach makes sense. And the rest of the world knowing some of the science behind our vaccine really likes what they see. We received 1 billion doses preorder already for the vaccine. I think time will tell the success of the Russian approach.
Russia has released no scientific data on its testing and CNN is unable to verify the vaccine's claimed safety or effectiveness.

Fauci says he seriously doubts Russia has proven new vaccine is safe and effective
From CNN's Lauren Mascarenhas
After Russia said it had approved a coronavirus vaccine for use Tuesday, Dr. Anthony Fauci, the nation's top infectious disease expert, said he seriously doubts Russia has proven its vaccine is safe and effective.
“I hope that the Russians have actually, definitively proven that the vaccine is safe and effective. I seriously doubt that they've done that,” Fauci told Deborah Roberts of ABC News for a National Geographic event to broadcast Thursday. A portion of the interview was posted by National Geographic on Tuesday.
Fauci, the director of the National Institute of Allergy and Infectious Diseases, said that having a vaccine and proving that a vaccine is safe and effective are two different things.
“We have half a dozen or more vaccines,” Fauci said. “So if we wanted to take the chance of hurting a lot of people or giving them something that doesn't work, we could start doing this, you know, next week if we wanted to. But that's not the way it works.”
Fauci said that if and when Americans hear announcements from countries like Russia or China about vaccine development, they have to remember that the United States has certain safety and efficacy standards in place. Makers of the Russian vaccine have not yet released any data from human trials.
The US Food and Drug Administration has said that it will only approve a vaccine if it meets a 50% efficacy requirement.
In a statement emailed Tuesday, the World Health Organization said it is in touch with Russian scientists and authorities and looks forward to reviewing details of the trials. According to WHO, there are 28 vaccines in human trials around the world.

From CNN’s Jamiel Lynch
The North Georgia State Fair has been canceled, according to fair organizers in a statement.
“With utmost regret, the decision has been made to cancel the Superior Plumbing Presents North Georgia State Fair this year,” the statement said.
“Every effort has been made to find a viable solution for bringing the fair to fruition this year. However, between Cobb and Douglas Public Health notifying us of continued use of Jim R. Miller Park for Covid-19 testing through the end of the year, the extension of Governor Kemp’s Public Health State of Emergency, and an abundance of caution for the ongoing uncertainty of the pandemic, the difficult and heartbreaking decision has been made to cancel,” the statement said.
The fair was scheduled for Sept. 23 to Oct. 3.
The organizers are planning to hold a “Taste of the Fair” drive-thru experience giving people a chance to taste their favorite fair foods.
This is the first time the fair has been canceled since World War II.
