Pulse Oximeter Devices Have Higher Error Rate in Black Patients--New study

Pulse oximeters are one of the most commonly used tools in medicine. The small devices, which resemble a clothespin, measure blood oxygen when clipped onto a fingertip, and they can quickly indicate whether a patient needs urgent medical care.

Health providers use them when they take vital signs and when they evaluate patients for treatment. Ever since the pandemic started, doctors have encouraged patients with Covid to use them at home.

But in Black patients, the devices can provide misleading results in more than one in 10 people, according to a new study.

EU approves COVID-19 vaccine after agency gives safety OK

BRUSSELS (AP) — The European Union on Monday gave official approval for the coronavirus vaccine developed by BioNTech and Pfizer to be used across the 27-nation bloc, raising hopes that countries can begin administering the first shots to their citizens shortly after Christmas.

The EU’s executive commission gave the green light just hours after the European Medicines Agency said the vaccine meets safety and quality standards. Brussels had been expected to take two or three days to endorse the market authorization move.

“As we have promised, this vaccine will be available for all EU countries at the same time, on the same conditions,” said European Commission President Ursula von der Leyen. “This is a very good way to end this difficult year, and to finally start turning the page on COVID-19.”

Deliveries of the vaccine are expected to start this coming Saturday, with inoculations beginning across the EU between Dec. 27 and Dec. 29.

Here’s What People With Allergies Should Know About Covid Vaccines

Allergic reactions reported in two health workers who received a dose of Pfizer’s vaccine in Alaska this week have reignited concerns that people with a history of extreme immune flare-ups might not be good candidates for the newly cleared shots.

The two incidents follow another pair of cases in Britain. Three of the four were severe enough to qualify as anaphylaxis, a severe and potentially life-threatening reaction. But all four people appear to have recovered.

Boris Johnson orders a severe lockdown, saying a more infectious variant of the virus is ripping through Britain.

LONDON — Alarmed by what he called a faster-spreading variant of the coronavirus, Prime Minister Boris Johnson abruptly reversed course on Saturday and imposed a wholesale lockdown on London and most of England’s southeast.

The decision, which Mr. Johnson announced after an emergency meeting of his cabinet, came after the government got new evidence of a variant first detected several weeks ago in Kent, southeast of London, which the prime minister asserted was 70 percent more transmissible than previous versions. Cabinet ministers were told that in London, cases had nearly doubled in the last week, with the new variant accounting for 60 percent of those.
