Russia claims it's on track to approve Covid-19 vaccine by mid-August. But speed of process raises questions

Russia intends to be the first in the world to approve a coronavirus vaccine, in less than two weeks -- despite concerns about its safety, effectiveness and over whether the country has cut essential corners in development, CNN has learned. Russian officials told CNN they are working toward a date of August 10 or earlier for approval of the vaccine, which has been created by the Moscow-based Gamaleya Institute.

It will be approved for public use, with frontline healthcare workers getting it first, they said. CNNWorld 

Roche arthritis drug Actemra flunks COVID-19 study, but remdesivir combo data await

On the Covacta trial’s key secondary endpoint of death prevention by week four, a 19.7% death rate among Actemra patients didn't differ from the placebo group’s 19.4%. This marks the second major blow to the theory of targeting inflammatory molecule IL-6 in treating COVID-19. Earlier this month, Sanofi and Regeneron pulled the plug on a phase 3 trial of their rival IL-6 inhibitor Kevzara after finding the drug couldn’t help severely ill COVID-19 patients who were on mechanical ventilation.

First Phase 3 clinical trial of a coronavirus vaccine in the United States begins

The trial is expected to enroll about 30,000 adult volunteers and evaluates the safety of the Moderna/NIH vaccine and whether it can prevent symptomatic Covid-19 after two doses, among other outcomes. Volunteers will receive either two 100 microgram injections of the vaccine or a placebo about 28 days apart. Investigators and participants will not know who has received the vaccine. CNNHealth 

Can Masks Save Us From More Lockdowns? Here's What The Science Says

It seems obvious that masks would reduce the spread of a respiratory bug like the coronavirus to at least some degree. After all, when a healthy person wears a mask, the barrier filters out some airborne droplets containing the virus. Even more importantly, when a sick person wears a mask, the barrier holds in many of the viral droplets they exhale. NPR 

Study identifies 21 existing drugs that could treat COVID-19

Of the 21 drugs that were effective at blocking viral replication, the scientists found:

• 13 have previously entered clinical trials for other indications and are effective at concentrations, or doses, that could potentially be safely achieved in COVID-19 patients.
• Two are already FDA approved: astemizole (allergies), clofazamine (leprosy), and remdesivir has received Emergency Use Authorization from the agency (COVID-19).
• Four worked synergistically with remdesivir, including the chloroquine derivative hanfangchin A (tetrandrine), an antimalarial drug that has reached Phase 3 clinical trials.

How Long Are You Contagious With Covid-19 Coronavirus? Here’s A CDC Update

The CDC is now saying that if you have mild-to-moderate Covid-19, keep yourself isolated from other people for at least 10 days after you first noticed symptoms. You can discontinue this isolation after the 10-day mark if you haven’t had a fever for at least 24 hours and your other symptoms have improved. Note that not having a fever because you took a fever-reducing medication like Tylenol doesn’t count. Forbes 

Yale to lead trial of potential COVID-19 treatment

Yale School of Medicine and the biopharmaceutical firm AI Therapeutics have launched a multi-institutional clinical trial of a drug for treating COVID-19.

It's not just dexamethasone: Other steroids may be used to treat critically ill COVID-19 patients, study says

Dexamethasone isn’t the only steroid that has shown promise in the battle against COVID-19. Researchers at the Albert Einstein College of Medicine and Montefiore Health System led a study in which most of their patients took prednisone, another steroid in the same family as dexamethasone, and found patients with high inflammation levels were associated with a 75% reduction in risk of going on mechanical ventilation or dying.

NIH to start ‘flurry’ of large studies of potential Covid-19 treatments

In an interview, NIH Director Francis Collins characterized the studies as “really well-powered, rigorously designed clinical trials.” Among the trials, he said: studies of antiviral monoclonal antibodies to treat Covid-19 in both hospitalized patients and patients who can be treated at home; studies of drugs to quell overreaction of the immune system that the agency has picked from dozens of approved treatments; and studies of blood thinners in very sick Covid-19 patients to prevent problems caused by blood clots. Those treatment studies will be on top of the work that the NIH is also doing on vaccines, including the Covid-19 vaccine being developed by Moderna Therapeutics. STAT

Trial for COVID-19 drug successful in helping recovery

The drug, called SNG001, uses interferon beta protein, which is already produced naturally by the body to fight infections. By inhaling additional amounts directly into the lungs, researchers said the risk of a COVID-19 infection developing into a severe disease was reduced by 79%. AA

COVID-19 vaccine hopes rise after strong trial results in England

"We are seeing good immune response in almost everybody," said Dr. Adrian Hill, director of the Jenner Institute at Oxford University. "What this vaccine does particularly well is trigger both arms of the immune system," he said. Hill said that neutralizing antibodies are produced - molecules which are key to blocking infection. In addition, the vaccine also causes a reaction in the body's T-cells which help to fight off the coronavirus. ABC 

Will Russia be the first country to produce the World’s first Experimental COVID-19 vaccine in August?

The first human trial of the vaccine was a one-month test on 38 people, which ended this week. The researchers concluded that although the strength of this response is unknown, it is safe to use and induce an immune response. According to reports, Russian scientists claimed on Monday that they hope to launch the world’s first coronavirus experimental vaccine as soon as possible next month. Kirill Dmitriev, head of the Russian Direct Investment Fund (RDIF), announced that a larger trial of the third phase, including numerous thousand people, would begin in August. Inventiva

Fauci really thinks a breakthrough coronavirus drug will be here by fall

It’s not just novel coronavirus vaccine candidates that are in advanced phases of human trials right now, and it’s not just COVID-19 vaccines that could be ready for emergency use before the end of the year. We’ve often talked about a new type of medicine that could work well against the new virus. On top of that, this category of drug tech can be applied to other infectious diseases to offer vaccine-like protection, though it wouldn’t be long-lasting immunity like you get with vaccines. The best part is that Dr. Anthony Fauci is already confident this new type of coronavirus drug could be available as soon as this coming fall. BGR

FDA approves Quest COVID-19 test for 'pooled' sample use

With pooling, instead of running each person’s test individually, laboratories would combine parts of samples from several people and test them together. A negative result would clear everyone in the batch. A positive result would require each sample to be individually retested. Pooling works best with lab-run tests, which take hours — not the much quicker individual tests used in clinics or doctor’s offices.ABCNews

Cholesterol-lowering meds have potential to downgrade COVID-19's threat to that of the common cold

With this information in hand, Nahmias and tenOever began to screen FDA-approved medications that interfere with the virus' ability to reproduce. In lab studies, the cholesterol-lowering drug Fenofibrate (Tricor) showed extremely promising results. By allowing lung cells to burn more fat, fenofibrate breaks the virus' grip on these cells, and prevents SARS CoV-2's ability to reproduce. In fact, within only five days of treatment, the virus almost completely disappeared. MedicalXpress

Moderna’s COVID-19 vaccine produces immune response in early trial

The interim analysis of the phase 1 study of the candidate, mRNA-1273, evaluated a two-dose vaccination schedule of the shot given 28 days apart across three dosages – 25, 100, 250 µg – in 45 healthy adults aged 18-55 years. The initial results from participants who received both doses showed mRNA-1273 produced rapid and strong immune responses against SARS-CoV-2, the virus which causes COVID-19. Despite producing a promising immune response in all patients, the vaccine also caused side effects, including mild to moderate fatigue, chills, headache and muscle pain.PMLive

COVID-19 vaccines are on the fast-track to approval. How will we know they're safe?

In June, the FDA issued guidelines for the approval of COVID-19 vaccines. In those guidelines, the agency described what safety evaluations a vaccine would need to pass and noted that a vaccine should show at least 50% efficacy in clinical trials, meaning that under perfect conditions, people who get the vaccine would be at least half as less likely to be infected with the coronavirus compared with unvaccinated people.   LiveScience

Even without a Covid-19 vaccine, there's reason for hope

Much like the vaccines that have showed early promise, these drugs too will need more testing before their safety and efficacy can be proven. But the timeline for testing these drugs is much shorter than for a vaccine, in large part due to how quickly and easily their efficacy can be determined. For antivirals and monoclonal antibodies, you know whether the virus works within a matter of days -- either the viral load in the patient goes up or it goes down -- and with very few individuals. Our first effective treatment for HIV, an antiviral, was proven in a group of just 19 patients given the drug. CNN

Research suggests protective effect of influenza vaccine against COVID-19 severity and mortality

A new study involving over 92,000 patients with COVID-19 in Brazil shows that the odds of severe disease, ventilatory support requirement, and death are reduced with a recent trivalent flu vaccine. This seems to indicate that these vaccines should be used as widely as possible to reduce the risk of severe COVID-19, especially among high-risk groups. NewsMedical

Oxford COVID-19 vaccine trials move to stage 3 human trials

Preliminary findings from that phase of the study are expected within the month. While researchers work to analyze those results, they will simultaneously move forward with a separate round of studies, testing the impact of remdesivir plus another medication. NBC 

How to Catch COVID-19

• You’re not likely to get it from touching a contaminated surface
• And you’re not likely to catch it from quick encounters with other people outside. (That doesn’t mean you can’t contract the virus – those activities just aren’t nearly as high of risk)
• You’re most likely to catch the virus when you talk to someone less than 6 feet away for at least 15 minutes without wearing a facemask
