COVID-19 Vaccine Landscape (Bullseye)
February 9, 2021
The COVID-19 pandemic has generated intense interest in efforts by the global pharmaceutical community to develop COVID-19 vaccines. The BizInt Smart Charts team has applied tools in the BizInt Smart Charts product family, including VantagePoint – Smart Charts Edition (VP-SCE), to create a concise visualization of the leading COVID-19 vaccines in development.
You can find the current status of our landscape in our COVID-19 Vaccine Dashboard.
Important Changes To The COVID-19 Bullseye
The update of February 9, 2021 represents a reset in how we are creating this bullseye.
Starting with this update, we are building the landscape from commercial drug pipeline databases, which are more suited to tracking development in a field like this. We look forward to sharing our experiences, and the challenges we face, going forward.
When we started this project last summer, the field was still new and the best sources of information were the clinical trial registries, particularly clinicaltrials.gov. Now that several vaccines have been approved around the world, and many others have failed, we are faced with the limitations of trial registry data for this type of project.
At the AVM 2021 conference this month, Diane Webb presented lessons learned from this project. You can find the slides on our presentations page.

About the COVID-19 Vaccine Bullseye
The COVID-19 Bullseye provides an ‘at-a-glance’ review of the vaccine landscape – showing highest trial phase, vaccine technology, and lead organization for each vaccine.
Trial phases are shown in the concentric rings, with programs closer to the center further along in the development process (from Phase 1 in the outer ring to Launched at the center).
The National Institutes of Health describe clinical trial status as follows:
- Phase 1:
Studies that are usually conducted with healthy volunteers and that emphasize safety. The goal is to find out what the drug's most frequent and serious adverse events are and, often, how the drug is metabolized and excreted.
- Phase 2: Studies that gather preliminary data on effectiveness (does the vaccine invoke an immune response). Safety continues to be evaluated, and short-term adverse events are studied.
- Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
- Authorized: Vaccines will be considered to be approved once they have received either full approval from the US FDA or EMA or have been granted FDA Emergency Use Authorization (EUA) or EMA Conditional Marketing Authorisation (CMA).
The bullseye is divided into sectors representing vaccine technologies, which are described in the sidebar at right.
Each vaccine is labeled by a commonly used name and by the organizations leading the development of the vaccine.
What Has Changed In This Update?
Surprisingly little activity in ClinicalTrials.gov given how much time the news is spending discussing COVID-19 vaccines.
There is one "new" vaccine program in this update, GS-19N from Genexine. This program is a new formulation of GS-19, which was previously on the bullseye.
News reports have surfaced that several projects have been abandoned, but the registry entries in ClinicalTrials.gov do not reflect these changes. We are experimenting with a new approach to this landscape, which we hope to introduce next update.
This update included over 4,500 records, of which 72 represented new interventional trials.
Do You Find This Bullseye Interesting?
The COVID-19 Bullseye is an example of a BizDash project. BizDash (BizInt Smart Strategy Dashboards) is a service offered by the BizInt team. We use BizInt Smart Charts tools with supported drug pipeline, clinical trial and biomedical literature databases to create data-centric reports and visualizations targeted to your analytic needs.

- May 4, 2021 — A small update this time, with one new vaccine project and one phase change.
- April 20, 2021 — Updating both the US/UK/Europe bullseye and the bullseye for programs in the rest of the world. Four new vaccine programs appear.
- April 6, 2021 — We have updated the US/UK/Europe bullseye and the corresponding piano chart. Two new vaccines appear, one starting trials, and one newly listing trials in the regions we are watching.
- March 23, 2021 — We have updated both the US/UK/Europe bullseye and the Rest Of World version, as well as adding a piano chart to show some of the detail on the US/UK/Europe data. Quite a bit of updates... click through to read more.
- March 9, 2021 — This update looks at the US/UK/Europe vaccine development, and reflects the emergency authorization of the Janssen (J&J) vaccine.
- February 23, 2021 — The first update of our COVID-19 landscape using commercial data sources. We have split the data set into programs in the US/UK/Europe and a second set for the remaining vaccines, which is easy with these databases.
- February 9, 2021 — A reset in our COVID-19 landscape, we have rebuilt the bullseye using data from commercial drug pipeline databases rather than clinicaltrials.gov. We are still working through the implications, but this is a good first look at the new direction.

These vaccines contain no part of the virus. DNA vaccines use gene technology to introduce RNA into the body. DNA contains the genetic instructions to make proteins. The body uses the DNA from the vaccine to make virus proteins which then cause the immune response. Several vaccines are in development using DNA technology, but none are approved.
- Immune cell
With this vaccine, live immune cells from healthy donors are used to induce a immune response. This is a novel technology.
Inactivated vaccines contain a killed version of the virus. This is the same technology used for the annual flu shot. Because the whole virus is present, there could be more side effects with this technology, but fewer than with a live vaccine.
These vaccines contain a weakened form of the live virus. This results in a strong, long lasting response with less need for multiple dose or annual vaccination. Because the whle virus is used there can be more side effects. The MMR vaccination is an example of this type of vaccine.
- Modified Antigen-Presenting Cells
Antigen-presenting cells have the part of the virus that induces the immune response on the surface. Rather than using COVID-19 or its components, this technology uses a different vector that has been modified to have the key COVID-19 proteins on the cell surface. In the case of COVID-19, these vaccines target the spike protein visible on the outside of the COVID-19 virus.
- Non-replicating viral vector
This technology uses a different virus instead of COVID-19 to induce the immune response. A non-replicating vector does not multiply in the body. Additionally, the vector may be a weakened version of a virus or the body may already be immune to the selected vector virus. This vector virus has been modified to produce virus proteins that induce the immune response. The U.S. Strategic National Stockpile includes a smallpox vaccine using this technology.
- Protein subunit
Rather than the whole virus like inactivated vaccines, these vaccines contain only the part that stimulates an immune response. Because it is only part of the virus, there may be fewer side effects. Some pertussis vaccines use this technology.
- Replicating viral vector
These vaccines use a different virus instead of COVID-19 to induce the immune response. This vector virus has been modified to produce COVID-19 virus proteins. A replicating vector can multiply in the body, but is weakened so that it does not cause disease and generally cannot replicate as rapidly. But because it is able to replicate, this increases the body's exposure. That could mean a stronger or longer lasting immune response.
These vaccines contain no part of the virus. RNA vaccines use gene technology to introduce RNA into the body. RNA transfers the genetic information from DNA to make proteins. The body uses the RNA from the vaccine to make virus proteins which then cause the immune response. Several vaccines are in development using RNA technology, but none are approved.
- Virus-like particle
VLP vaccines use gene technology to produce particles that resemble the shape of the virus. The particles can cause an immune response, but are non-infectious. This is the technology behind the HPV vaccines.
