Oxford COVID-19 vaccine developer cautious on 2020 roll-out

  • Oxford/AstraZeneca shot showed promise in early-stage trials
  • Medical officials differ on potential timeline for vaccines

LONDON: The University of Oxford’s possible COVID-19 vaccine could be rolled out by the end of the year but there is no certainty, the lead developer of the vaccine said on Tuesday.
The experimental vaccine, which has been licensed to AstraZeneca, produced an immune response in early-stage clinical trials, data showed on Monday, preserving hopes it could be in use by the end of 2020.
“The end of the year target for getting vaccine roll-out, it’s a possibility but there’s absolutely no certainty about that because we need three things to happen,” Sarah Gilbert told BBC Radio.
She said it needed to be shown to work in late-stage trials, there needed to be large quantities manufactured, and regulators had to agree quickly to license it for emergency use before large numbers of people could be vaccinated.
England’s Chief Medical Officer Chris Whitty and his deputy Jonathan Van-Tam took differing views on the potential timeline.
“The chance of us getting a vaccine before Christmas that actually is highly effective are, in my view, very low,” Whitty told lawmakers.
Van-Tam, however, said he was “cautiously optimistic that we will have some vaccine this side of Christmas.”
The Oxford scientists had eyed a million doses of the potential vaccine to be produced by September.
Although the deal with AstraZeneca has provided manufacturing capacity to do that, the lower prevalence of the novel coronavirus in Britain has complicated the process of proving its efficacy.
Late-stage trials crucial for providing data are under way in Brazil and South Africa and are due to start in the United States also.
There are no approved vaccines yet for COVID-19, but the World Health Organization has said AstraZeneca’s shot is one of the leading candidates.


Florida braces for frost and possible snow flurries as winter storms hit other parts of the US

Florida braces for frost and possible snow flurries as winter storms hit other parts of the US

  • The worst seems to be heading toward the Carolinas, but the Sunshine State’s humans, animals and even plants are preparing for winter weather

MIAMI: Florida won’t be getting hit with massive blankets of snow and ice like the rest of the US, but even frosty windshields and a few flurries can feel like Antarctica to people with permanent sandal tans.
The Midwest and South have been getting major winter storms for several days, and a giant cyclone forecast in the Atlantic Ocean is expected to pull that cold weather east as a powerful blizzard this weekend. The worst seems to be heading toward the Carolinas, but the Sunshine State’s humans, animals and even plants are preparing for winter weather.
Florida could experience record cold
Ana Torres-Vazquez, a forecaster with the National Weather Service in Miami, said a cold front earlier this week has already caused temperatures to dip some, but the region could experience record-setting cold this weekend.
“It looks like temperatures across South Florida are dipping into the 30s (Fahrenheit) for most of the metro area and maybe into the 20s for areas near Lake Okeechobee,” Torres-Vazquez said. “And then the windchill could make those temperatures feel even cooler.”
Residents of South Florida are less likely to have heavy coats and other winter clothes, so Torres-Vazquez said it’s important to layer up lighter clothing and limit time spent outside.
Moving north, Tony Hurt, a National Weather Service forecaster for the Tampa Bay area, said there’s a 10 to 20 percent chance of snowfall in that region this weekend.
“Most likely if there’s any snow that does actually materialize, it’ll be primarily in the form of flurries, no accumulations,” Hurt said.
The last two times the area got snow was flurries in January 2010 and December 1989. The record for snowfall was in January 1977, with 2 inches (5 centimeters) of snow about 20 miles (32 kilometers) east of Tampa.
Despite the possibility of snow, Tampa will host the annual Gasparilla Pirate Fest on Saturday. And on Sunday, the Tampa Bay Lightning are set to host the Boston Bruins for an outdoor NHL game at the Tampa Bay Buccaneers’ home NFL stadium.
Few tourists visiting Florida will be swimming in the ocean or laying out on sunny beaches this weekend, but many attractions will remain open. Most of Walt Disney World and Universal Orlando will operate normally, though their water parks will be closed. Most of the state’s zoos and animal parks will also remain open while keepers take steps to protect the inhabitants.
Zoo keepers working to keep animals safe and warm
Zoo Miami spokesman Ron Magill said keepers have been setting up heaters and moving reptiles and smaller mammals to indoor enclosures, while primates like chimpanzees and orangutans are given blankets to keep themselves warm. Big cats and large hoofed animals generally do well in colder temperatures and don’t require much assistance from keepers.
“It can be invigorating for animals like the tiger, so they’ll actually become more active,” Magill said.
Outside the safety of the zoo, Florida’s native wildlife has evolved and learned to survive occasional cold snaps, though casualties will still occur, Magill said. Manatees, for example, have spent decades congregating at the warm-water outflows of about a dozen power plants around Florida.
But invasive, nonnative animals like iguanas and other exotic reptiles will suffer the most, Magill said. Iguanas in South Florida famously enter a torpid state during cold periods and even fall out of trees. They usually wake up when the temperature increases, but many will die after more than a day of extreme cold.
“At the end of the day, they don’t belong here, and that might be nature’s way of trying to clean that up a little bit,” Magill said. “That is a part of natural selection.”
Protecting crops is a priority for farmers
Florida’s agriculture industry is also bracing for the cold. Farmers are working to safeguard their crops as winter harvest continues and spring planting begins in some areas, Florida Fruit & Vegetable Association spokeswoman Christina Morton said.
“Preparations vary by crop and include harvesting and planting ahead of the freeze, increasing water levels in ditches, using overhead irrigation, and, in some cases, deploying helicopters to protect sensitive fields,” Morton said.
The Florida deep freeze comes as the arctic blast from Canada also spreads into southern states where thousands of people remain without power to heat their homes, and people in mid-Atlantic states prepare for possible blizzard conditions as a new storm is expected to churn along the East Coast.
Temperatures in hard-hit northern Mississippi will feel as cold as minus 5 degrees Fahrenheit (minus 21 degrees Celsius) when the expected strong winds are factored in, National Weather Service forecasters say. People in a large part of the southeastern US were under a variety of alerts warning of extremely cold weather on the way.
The storm expected to hit the Eastern Seaboard has prompted more warnings in the Carolinas and nearby states. That storm is expected to bring heavy snow and strong winds, which could create “dangerous, near-blizzard conditions,” the weather service warned.
