WHO Calls on Pfizer to Make its COVID Pill More Available

The head of the World Health Organization called on Pfizer to make its COVID-19 treatment more widely available in poorer countries, saying Tuesday that the pharmaceutical company’s deal allowing generic producers to make the drug was insufficient. WHO Director-General Tedros Adhanom Ghebreyesus said during a news briefing that Pfizer’s treatment was still too expensive. He noted that most countries in Latin America had no access to Pfizer’s drug, Paxlovid, which has been shown to cut the risk of COVID-19 hospitalization or death by up to 90%.

Administration Expands Availability of COVID Antiviral Pill

President Joe Biden’s administration is taking steps to expand availability of the life-saving COVID-19 antiviral treatment Paxlovid, as it seeks to reassure doctors that there is ample supply for people at high risk of severe illness or death from the virus. Paxlovid, produced by Pfizer, was first approved in December. Supply of the regimen was initially very limited, but as COVID-19 cases across the country have fallen and manufacturing has increased it is now far more abundant.

Majority of Americans Want Masks for Travelers

A majority of Americans continue to support a mask requirement for people traveling on airplanes and other shared transportation, a new poll finds. A ruling by a federal judge has put the government’s transportation mask mandate on hold. The poll by The Associated Press-NORC Center for Public Affairs Research finds that despite opposition to that requirement that included verbal abuse and physical violence against flight attendants, 56% of Americans favor requiring people on planes, trains and public transportation to wear masks, compared with 24% opposed and 20% who say they’re neither in favor nor opposed.

FDA OKs Another Pfizer, Moderna COVID Booster for 50 and Up

U.S. regulators on Tuesday authorized another COVID-19 booster for people age 50 and older, a step to offer extra protection for the most vulnerable in case the coronavirus rebounds. The Food and Drug Administration’s decision opens a fourth dose of the Pfizer or Moderna vaccines to that age group at least four months after their previous booster. Until now, the FDA had cleared fourth doses only for people 12 and older who have severely weakened immune systems. The agency said this especially fragile group also can get an additional booster, a fifth shot.

WHO Will Turn to the Greek Alphabet to Help Avoid Stigma Around Coronavirus Variants

The World Health Organization is hoping to simplify the way the public talks about the growing number of variants of the coronavirus. It will start assigning different letters of the Greek alphabet to each new mutation of the virus. The new system takes the names of new variants of SARS-CoV-2 and moves them away from what can be sometimes confusing scientific nomenclature, or shorthand that puts heavy emphasis on where the variants were first discovered.

COVID Testing’s Value Shrinks as Vaccines Beat Back Virus

The Centers for Disease Control and Prevention said last week that most people who have received the full course of shots and have no COVID-19 symptoms don’t need to be screened for the virus, even if exposed to someone infected. The change represents a new phase in the epidemic after nearly a year in which testing was the primary weapon against the virus. Vaccines are now central to the response and have driven down hospitalizations and deaths dramatically.

FDA Says Single-Dose Shot From J&J Prevents Severe COVID

Johnson & Johnson’s single-dose vaccine offers strong protection against severe COVID-19, according to an analysis released Wednesday by U.S. regulators that sets the stage for a final decision on a new and easier-to-use shot to help tame the pandemic.

The long-anticipated shot could offer the nation a third vaccine option and help speed vaccinations by requiring just one dose instead of two. Food and Drug Administration scientists confirmed that overall the vaccine is about 66% effective at preventing moderate to severe COVID-19, and about 85% effective against the most serious illness. The agency also said J&J’s shot is safe.

Quick Treatment With Antibody-Laden Blood Cuts Risk of Severe COVID

A clinical trial in older adults with COVID-19 shows that an early dose of blood plasma from recovered people helps to prevent the progression to severe disease.

The plasma of people who have recovered from COVID-19 contains antibodies against SARS-CoV-2. But treatment with such plasma has had mixed results, and some scientists have suggested that plasma needs to be given early in the disease course to be effective. Fernando Polack at Fundación INFANT in Buenos Aires and his colleagues conducted a rigorous clinical trial to assess the effect of treatment with plasma within 72 hours of symptom onset. Participants included people over the age of 75 and those between 65 and 74 with at least one pre-existing condition such as diabetes. Read More

By the numbers: On January 11, there were 39,839 newly recorded confirmed cases in California. The state now has a total of 2,710,801 positive cases. There have been a total of 29,965 deaths in the state.

The Data on Coronavirus and Public Holidays

As worldwide coronavirus cases continue to surge, countries are grappling with how to manage big public holidays such as Christmas and Lunar New Year, which researchers are warning could become superspreader events.

“We’re already at a high level of community spread, and we’re about to see a lot of people traveling and gathering indoors,” says Julia Marcus, an infectious-disease epidemiologist at Harvard Medical School in Boston, Massachusetts. “It’s hard to see any way that this is going to go well.”

Nature examines what scientists have already learned about the spread of COVID-19 during holidays. Read More

California Rolls Out New App to Alert People of Potential COVID-19 Exposure

As California’s latest coronavirus surge spreads at a record-setting pace, state officials on Monday unveiled a new cell phone app aimed at helping Californians track their exposure to the virus.

Starting Thursday, December 10, Californians will be able to opt into the new app — dubbed CA Notify — and receive notifications on their cell phones informing them if they have been in close proximity to someone who has tested positive for the virus.

California joins more than a dozen states, including New York, Michigan and Washington, to launch exposure notification apps in recent months. Read More

COVID-19 Travel Health Notice Levels and Testing for International Travelers

On November 21, CDC revised the Travel Health Notice system for COVID-19 and released new recommendations for testing before and after international air travel to help the public make informed decisions for safer, healthier, and more responsible travel during the COVID-19 pandemic.

CDC’s Travel Health Notices inform travelers and clinicians about current health issues in destinations around the world. For most diseases, the Travel Health Notices have 3 levels. This new 4-level travel health notice system is specific to COVID-19 and details the level of COVID-19 in international destinations and U.S. territories. The COVID-19 Travel Health Notices now indicate low, moderate, high, and very high levels of COVID-19 for each destination and are based primarily on incidence rate (or new case counts in destinations with populations of 200,000 or less) and trajectory of new cases (whether new cases over the past 28 days are increasing, decreasing, or stable).

Pfizer Says its Coronavirus Vaccine is 90% Effective in a Large Trial

Today, Pfizer and BioNTech announced that their experimental vaccine against the novel coronavirus is more than 90 percent effective in preventing the disease COVID-19, based on initial analysis of results from their large phase III trial. The two companies also report that no serious safety concerns have arisen thus far. To create the vaccine, researchers genetically engineered SARS-CoV-2 genes, captured their blueprint, embedded that blueprint into an RNA molecule in solution and injected the solution into the bodies of trial participants. The trial’s data have not yet been submitted for peer-review publication. If the results hold up, Pfizer and BioNTech say they could manufacture large quantities of the genetically engineered vaccine quickly. Read More

New “Close Contact” Guidelines (10.21.20)

The U.S. Centers for Disease Control (CDC) this week broadened its definition of a “close contact” with an infected person, thereby expanding “the pool of people considered at risk of contracting the novel coronavirus,” writes Lena H. Sun at The Washington Post (10/21/20). To be considered a “close contact,” the 15-minute exposure time for individuals within six feet is now cumulative or total time during a 24-hour period, not sequential, consecutive time. State and county health departments use the definition for contract tracing efforts, the story states. The CDC’s change “is likely to have its biggest impact in schools, workplaces, and other group settings where people are in contact with others for long periods of time,” Sun writes.

New Reopening Guidelines (8.28.20)

On August 28th, Governor Newsom released a new reopening framework with four tiers with colors attached to them to indicate severity. Case rates and test positivity rates will be the metrics that determine movement within the tiers which run from purple (the most restrictive) to red to orange to yellow (the least restrictive). These categories replace the state watchlist that had previously dictated whether counties could reopen or would need to close.

Reopening rollback (7.13.20)

On July 13, Gov. Newsom ordered a rollback of the state’s reopening plan in an attempt to curb the recent resurgence of COVID-19. The rollback mandates closure of restaurants, wineries, movie theaters, family entertainment centers, zoos, museums and cardrooms throughout the state. Newsom ordered even more business sectors to close in counties that are on the state’s monitoring list for more than three days; these include gyms, hair salons and barbershops, nail salons, indoor malls, non-essential offices, and places of worship.
