Moderna coronavirus vaccine shows ‘promising’ safety and immune response results in published Phase 1 study, but more research is needed (July 15) – The Phase I trial was also evaluating the safety of the vaccine. The side effects were generally mild to moderate, including fatigue, chills, headache, muscle pain, and pain at the injection site. The authors of the study indicated there were “no trial-limiting safety concerns.” The more moderate side effects were typically observed in the higher dose of the vaccine, and typically more after the second dose. In the study, about 80% described fatigue at the second 100-microgram dose, 60% reported headache, and 53% described muscle pain. They all went away in a day or two.

Covid Vaccine Front-Runner Is Months Ahead of Her Competition (July 14) – The University of Oxford candidate, led by Sarah Gilbert, might be through human trials in September. AstraZeneca has lined up agreements to produce 2 billion doses. Could this be the one?

Elegant but unproven, RNA experiments leap to the front in coronavirus vaccine race. Will they work? (July 5) – Scientists are pushing to develop, and possibly manufacture, vaccines in a completely new way. This promising — but unproven — new generation of vaccine technologies is based on deploying a tiny snip of genetic code called messenger RNA to trigger the immune system. It has never before been approved for use.

A Covid-19 Vaccine Shows Encouraging Signs (July 1) – Developed by Pfizer and BioNTech, an experimental vaccine spurred immune responses in a small trial of humans.

WHO, partners unveil ambitious plan to deliver 2 billion doses of Covid-19 vaccine to high-risk populations (June 26) – The World Health Organization and key partners unveiled a plan Friday to purchase 2 billion doses of Covid-19 vaccines for the highest risk populations of the world. The plan anticipates that by the end of 2021, the doses could be delivered to countries to vaccinate high risk individuals, likely including health care workers, people over the age of 65, and other adults who suffer from conditions like diabetes. The cost is estimated at $18.1B to deliver on the plan. The effort is one pillar of the WHO’s effort to ensure all countries have access to Covid-19 vaccines, therapeutics, and diagnostics, called the ACT Accelerator, short for Access to Covid-19 Tools.

Finding Antibodies that Neutralize SARS-CoV-2 (June 18) – The good news is that when researchers looked at individuals who mounted a strong immune response, they were able to identify three antibodies that were extremely effective at neutralizing SARS-CoV-2. By mass-producing copies of these antibodies as so-called monoclonal antibodies, the researchers can now better evaluate their potential as treatments to help people who don’t make strongly neutralizing antibodies, or not enough of them.

Emergent BioSolutions, BARDA reach $628M deal to manufacture COVID-19 vaccine hopefuls (June 1) – The contract is part of the government’s “Operation Warp Speed” development initiative to speed promising COVID-19 vaccines through clinical trials and into mass production before the end of 2020.

Merck to Acquire Austrian Vaccine Maker Themis Bioscience to enter COVID-19 race (May 26) – Themis has a broad pipeline of vaccine candidates and immune-modulatory therapies developed using its innovative measles virus vector platform based on a vector originally developed by scientists at the Institut Pasteur and licensed exclusively to Themis for select viral indications. In March, Themis joined a consortium together with the Institut Pasteur and The Center for Vaccine Research at the University of Pittsburgh, supported by funding from the Coalition for Epidemic Preparedness Innovations (CEPI), to develop a vaccine candidate targeting SARS-CoV-2 for the prevention of COVID-19.

AstraZeneca advances response to global COVID-19 challenge as it receives first commitments for Oxford’s potential new vaccine (May 21) – First agreements to supply at least 400 million doses; Company has total capacity sourced for one billion doses through 2020 and into 2021; continues to increase capacity further. More than $1bn US BARDA investment to support development and production of the vaccine

Vaccine experts say Moderna didn’t produce data critical to assessing Covid-19 vaccine (May 19) – While Moderna blitzed the media, it revealed very little information — and most of what it did disclose was not a lot of data. The company’s statement led with the fact that all 45 subjects (in this analysis) who received doses of 25 micrograms (two doses each), 100 micrograms (two doses each), or a 250 micrograms (one dose) developed binding antibodies. It was that eight volunteers — four each from the 25-microgram and 100-microgram arms — developed neutralizing antibodies. We don’t know results from the other 37 trial participants. This doesn’t mean that they didn’t develop neutralizing antibodies. Moderna disclosed the findings from eight subjects because that’s all it had at that point.

Google sister-company Verily is launching an antibody research study for Covid-19 (May 18) – Verily is adapting its existing clinical trial technology, Project Baseline, to the coronavirus. Its initial focus will be to study antibody testing. There are still many unknowns when it comes to antibody tests. And there’s a wide variation in the accuracy of the tests. 

Coronavirus Vaccine Trial by Moderna Shows Promising Early Results (May 18) – The company said its preliminary test in 8 healthy volunteers was safe. It is on an accelerated timetable to begin a larger human trial soon.

How Long Will a Vaccine Really Take? (April 30) – Great overview with interactive infographic on how long it takes to develop a vaccine, and why even 18 months for a vaccine against COVID is a dramatic acceleration.

The race for coronavirus vaccines: a graphical guide (April 28) – More than 90 vaccines are being developed against SARS-CoV-2 by research teams in companies and universities across the world. Researchers are trialling different technologies, some of which haven’t been used in a licensed vaccine before.

Sanofi is preparing to manufacture 100 million doses of COVID-19 vaccines (April 24) – There are 76 vaccine candidates for COVID-19, five of which are in clinical trials. It will take at least 18 months to determine if these vaccines are effective and safe enough to distribute en masse. Then, distributing them to millions of people will require an incredible feat of manufacturing. To address this problem, the company is looking at how it can use existing manufacturing space to ramp up COVID-19 vaccines.

Single-Dose Adenovirus-Based COVID-19 Vaccine Planned (April 24) – Three European biotech companies agreed to collaborate on the development and large-scale manufacture of a novel adenoviral vector-based vaccine against COVID-19.

Sanofi Expands COVID-19 Pipeline with Translate Bio Partnership (March 27) – The COVID-19 collaboration—whose value was not disclosed—is intended to combine vaccine expertise and external research networks of Sanofi Pasteur, Sanofi’s vaccines global business unit, with Translate Bio’s mRNA platform, which the companies will apply to discover, design, and manufacture SARS-CoV-2 vaccine candidates.

First Results From Moderna Covid-19 Vaccine May Take Two More Months (March 25) – Moderna announced dosing the first patient in the early stage study of mRNA-1273 on March 16. The trial in 45 healthy people is being run by the National Institutes of Health’s National Institute of Allergy and Infectious Diseases, with patients in the study getting two doses of the vaccination 28 days apart. While NIH has control over when results will be disclosed, management guided to data availability in the near-term and suggested that the first data release will likely include a full cohort (>3-5 patients) to reflect the totality of the scientific picture.

Mount Sinai to Begin the Transfer of COVID-19 Antibodies into Critically Ill Patients (March 24) – The Mount Sinai Health System plans to initiate a procedure known as plasmapheresis, where the antibodies from patients who have recovered from COVID-19 will be transferred into critically ill patients with the disease, with the expectation that the antibodies will neutralize it. The process of using antibody-rich plasma from COVID-19 patients to help others was used successfully in China, according to a state-owned organization, which reported that some patients improved within 24 hours, with reduced inflammation and viral loads, and better oxygen levels in the blood.

As the First Coronavirus Vaccine Human Trials Begin, Manufacturer Is Already Preparing to Scale Production to Millions (March 23) – The vaccine will be studied first in a group of 45 healthy volunteers, who have not been infected with SARS-CoV-2, the virus that causes COVID-19. In this group, scientists are looking to see if the shots are safe, and to test three different dosages to see which seems to activate the strongest immune response. Moderna uses mRNA, a genetic form of the virus’ genome, in its vaccine. When it’s injected into people, cells then process it so immune cells can recognize it and target it for destruction. Unlike the processes used to make most traditional vaccines, this method does not require growing huge amounts of the virus, which is time-consuming.
