February 1: “COVID-19: Novavax Jab ‘Effective Against UK Variant’” by Nicky Broyd, Medscape

The MHRA is continuing its rolling assessment of the coronavirus vaccine from the US drug company Novavax after the company reported it was effective against the UK variant with an overall efficacy of 89.3%. The phase 3 UK trial in collaboration with the National Institute for Health Research (NIHR) vaccine registry involved 15,000 participants aged 18-84, with 27% aged over 65. There were 62 positive cases, 56 of them in the placebo group. Half the cases were the UK variant of the virus.

February 1: “J&J Vaccine 85% Efficacious Against Severe COVID Globally” by Damian McNamara, Medscape 

The Janssen/Johnson & Johnson single-dose adenovirus vaccine provides 85% efficacy globally against severe COVID-19 illness, and it is 72% efficacious against moderate-to-severe illness in the US, according to highly anticipated interim Phase 3 results announced this morning.

February 1: “Additional Covid-19 Vaccines Bring Choices–and Complications–to the Rollout” by Andrew Joseph and Olivia Goldhill, STAT News

It’s always good for consumers to have options, right? And indeed, the United States should soon have three Covid-19 vaccines being injected into people’s arms, with more potentially on the way in the coming months, accelerating the race to vaccinate hundreds of millions of people as quickly as possible. But all vaccines are not equal, and increasingly, health authorities and providers will be dealing with shots with varying attributes: different storage requirements, efficacy, dosing regimens, and manufacturing platforms.

February 1: “Older Adults Without Family or Friends Lag in Race to Get Vaccines” by Judith Graham, Kaiser Health News

A divide between “haves” and “have-nots” is emerging as older adults across the country struggle to get covid-19 vaccines. Seniors with family members or friends to help them are getting vaccine appointments, even if it takes days to secure them. Those without reliable social supports are missing out.

February 2: “The Sputnik V Vaccine and Russia’s Race to Immunity” by Joshua Yaffa, The New Yorker

In fact, Russian scientists hadn’t published any data from their Phase I and Phase II trials, which test a vaccine’s safety and potential for efficacy among a limited number of volunteers, and hadn’t even started Phase III, which tests the vaccine in a much larger group of volunteers, using a placebo as a control. Still, Sputnik V had already begun to make its way through Russian society.

February 2: “Covid Deaths Are Starting to Drop in Every Part of the U.S.” by Jonathan Levin, Bloomberg

Covid-19 deaths have begun to decline in every section of the U.S., the latest sign of relief as cases continue to drop and the vaccination push accelerates. The virus has been receding in the U.S. for about three weeks, but reported deaths — the lagging indicator that’s the ultimate measure of Covid’s impact — had remained near record levels.

February 2: “Why Are So Many Health-Care Workers Resisting the COVID Vaccine?” by Dhruv Khullar, The New Yorker

Despite confronting the damage of COVID-19 firsthand—and doing work that puts them and their families at high risk—health-care workers express similar levels of vaccine hesitancy as people in the general population. Recent surveys suggest that, over all, around a third of health-care workers are reluctant to get vaccinated against COVID-19.

February 3: “COVID-19 Virus May Prompt Body to Attack Itself” by Brenda Goodman, Medscape

An international team of researchers studying COVID-19 has made a startling and pivotal discovery: The virus appears to cause the body to make weapons to attack its own tissues. The finding could unlock a number of COVID’s clinical mysteries.

February 3: “Novavax and J&J COVID-19 Vaccines Are Effective, But the Virus Variant from South Africa Poses Problems” by Ryan Cross, Chemical & Engineering News 

The Novavax shots were only 60% effective in South Africa, and the J&J vaccine only 57% effective in that country. Both companies found that more than 90% of the people who tested positive for COVID-19 and had their virus samples sequenced were infected with the B.1.351 variant, supporting the growing concern that some new variants of the virus could hinder the effectiveness of the vaccines.

February 3: “New Vaccine Puzzle: Who Should Get Which Shot?” by Benjamin Mueller and Rebecca Robins, The New York Times

First came the good news. The European Union authorized a third vaccine. Then, the bad news. Regulators in country after country suggested restricting it to younger people until more testing was done. The decisions marked the start of a delicate new phase of vaccination drives, one in which a growing menu of coronavirus vaccines was accompanied by contentious debates about who should be given which shots.

February 3: “In the Vaccine Scramble, Cancer Patients Are Left Behind” by Dani Blum, The New York Times

Facing conflicting guidance and logistical chaos, many cancer patients are struggling to navigate the bumpy rollout of the Covid-19 vaccination campaign. Ideally, cancer patients who take immunosuppressant medications should receive vaccinations under the care of a doctor, or in a cancer center, where they can be closely monitored and encounter fewer people than they would at a mass distribution site. But the limited availability of the vaccine, plus the havoc and confusion surrounding the rollout, leaves patients grasping for answers.

February 4: “Physicians Face Potential Peril with Leftover Vaccine Doses” by Marcia Frellick, Medscape

A Texas judge last week dismissed a theft charge against an emergency medicine physician recently fired from his public health job after he gave leftover COVID-19 vaccine doses to people he knew–highlighting the difficult position many clinicians find themselves in when there are unused doses but no one is on hand to administer them to and the clock is ticking.

February 4: “COVID-19: Antibodies ‘Remain for at Least 6 Months’” by Peter Russell, Medscape

A study has found that 99% of people who tested positive for SARS-CoV-2 retained antibodies to the virus for 3 months after infection. Researchers at UK Biobank found that 87.8% remained seropositive for the full 6 months that the study lasted. The discovery indicated that the antibodies produced following natural infection may provide a degree of protection for most people, scientists said.

February 4: “New COVID-19 Monoclonal Antibody Data Could Shift Clinical Practice” by Eleanor Cummins, Medscape

New data from phase 3 trials of monoclonal antibodies for patients with recent COVID-19 diagnoses, or at high risk for SARS-CoV-2 infection, could move the needle on clinician acceptance of the treatments, experts say.

February 4: “Exclusive: Indigenous Americans Dying from Covid at Twice the Rate of White Americans” by Nina Lakhani, The Guardian

February 4: “With a Seductive Number, AstraZeneca Study Fueled Hopes That Eclipsed Its Data” by Matthew Herper and Helen Branswell, STAT News

Media reports seized on a reference in the paper from Oxford researchers that a single dose of the vaccine cut positive test results by 67%, pointing to it as the first evidence that a vaccine could prevent transmission of the virus. But the paper, which has not yet been peer-reviewed, does not prove or even claim that — although it hints at the possibility.

February 4: “‘Cruel’ Digital Race for Vaccines Leaves Many Seniors Behind” by Will Stone, Kaiser Health News

With millions of older Americans eligible for covid-19 vaccines and limited supplies, many continue to describe a frantic and frustrating search to secure a shot, beset by uncertainty and difficulty. The efforts to vaccinate people 65 and older have strained under the enormous demand that has overwhelmed cumbersome, inconsistent scheduling systems.

February 4: “Could Mixing COVID Vaccines Boost Immune Response” by Heidi Ledford, Nature

Researchers in the United Kingdom have launched a study that will mix and match two COVID-19 vaccines in a bid to ease the daunting logistics of immunizing millions of people — and potentially boost immune responses in the process.

The World Health Organization and its Covax partners cautioned Monday against dismissing AstraZeneca’s COVID vaccine after several setbacks, insisting it remained an important, life-saving tool. The AstraZeneca vaccine is currently a vital part of Covax, which was set up to procure COVID-19 vaccines and ensure their equitable distribution around the world.

February 8: “New Variants Raise Worry About COVID-19 Virus Reinfections” by Marilyn Marchione, Associated Press

Evidence is mounting that having COVID-19 may not protect against getting infected again with some of the new variants. People also can get second infections with earlier versions of the coronavirus if they mounted a weak defense the first time, new research suggests. How long immunity lasts from natural infection is one of the big questions in the pandemic.

February 9: “US FDA Gearing Up for Rapid Review of Potential COVID-19 Booster Shots” by Reuters Staff, re-published on Medscape

February 9: “‘The Death Market’: Oxygen Shortage Leaves Mexicans to Die at Home” by Natalie Kitroeff and Oscar Lopez, The New York Times

After surviving his own bout with the coronavirus and then losing his job, Mr. Hernández began selling oxygen tanks out of his car. Then a second wave of the coronavirus slammed into Mexico this winter and demand for oxygen exploded, spawning a national shortage of devices that deliver the lifesaving resource. Prices spiked. A black market metastasized.

February 9: “Covid-19 Vaccine Scams Spread Under Facebook and Telegram’s Watch” by Brian Barrett, Wired

Scammers have flooded Facebook and other social media platforms with Covid-19 scams for almost as long as the disease has had a name. Now, as desperation builds for access to a limited vaccine supply, internet charlatans have escalated in kind, offering shipments of doses in Facebook groups and Telegram chats.

February 9: “US Vaccine Drive Complicated by 1st, 2nd Dose Juggling Act” by Candice Choi and Marion Renault, Associated Press

The U.S. has entered a tricky phase of the COVID-19 vaccination effort as providers try to ramp up the number of people getting first shots while also ensuring a growing number of others get second doses just when millions more Americans are becoming eligible to receive vaccines. The need to give each person two doses a few weeks apart vastly complicates the country’s biggest-ever vaccination campaign.

February 10: “Pandemic-Fueled Alcohol Abuse Creates Wave of Hospitalizations for Liver Disease” by Eli Cahan, Kaiser Health News

As the pandemic sends thousands of recovering alcoholics into relapse, hospitals across the country have reported dramatic increases in alcohol-related admissions for critical diseases like alcoholic hepatitis and liver failure.

February 11: “Pfizer Vaccine Found to Give Strong Immune Response to New Covid Variants” by Lina Geddes, The Guardian

People who have received two doses of the Pfizer vaccine have been found to have strong T-cell responses against the Kent and South African variants of Covid, suggesting that the vaccine will continue to protect against serious disease in the coming months. In the first study to test immune responses against the variants circulating in populations, researchers found that although antibody responses against the new variants were blunted, they may still be high enough to protect most people from becoming infected, after a second dose of vaccine has been given.

February 11: “The Newest Diplomatic Currency: Covid-19 Vaccines” by Mujib Mashal and Vivian Yee, The New York Times

February 12: “‘An Existential Threat’: Disabled and Chronically Ill Californians Criticize Vaccine Policy” by Maanvi Singh, The Guardian

Disabled and chronically ill Californians say that the state’s coronavirus vaccine distribution is leaving them in the lurch, as the death toll in the country’s most populous state continues to climb. California abruptly announced last month that it was changing its vaccination policies to prioritize age, rather than underlying risk, in deciding who will get the inoculation next.

February 12: “Lack of Covid Data on People with Intellectual Disabilities ‘Comes with a Body Count’” by Katheryn Houghton, Kaiser Health News

Early studies have shown that people with intellectual and developmental disabilities have a higher likelihood of dying from the virus than those without disabilities, likely because of a higher prevalence of preexisting conditions.

February 15: “You Think the U.S. Has Vaccine Issues? 130 Countries Haven’t Even Started Vaccinating” by Jason Beaubien, NPR

In some countries, citizens are grumbling about the inefficient rollout of COVID-19 vaccines. It’s unclear exactly when doses will be available. Websites for appointments keep crashing. Lines are long. And then there are the 130 countries that “are yet to administer a single dose,” according to UNICEF. That’s 2.5 billion people who so far have been completely shut out of the global vaccine campaign. Many of these low- and middle-income countries are urgently shopping for vaccines.

February 22: “People Who Have Had Covid Should Get Single Vaccine Dose, Studies Suggest” by Apoorva Mandavilli, The New York Times

Nearly 30 million people in the United States — and probably many others whose illnesses were never diagnosed — have been infected with the coronavirus so far. Should these people still be vaccinated? Two new studies answer that question with an emphatic yes. In fact, the research suggests that for these people just one dose of the vaccine is enough to turbocharge their antibodies and destroy the coronavirus — and even some more infectious variants.

February 22: “Long-Term Studies of COVID-19 Vaccines Hurt by Placebo Recipients Getting Immunized” by Richard Harris, NPR

Tens of thousands of people who volunteered to be in studies of the Pfizer-BioNTech and Moderna COVID-19 vaccines are still participating in follow-up research.
