Viral vector vaccines are used to deliver genetic material or DNA via vaccines. This DNA is then transcribed by the recipient's host cells to elicit an immune response. To date, only 6 viral vector vaccines have been approved by the United States FDA for use in humans-two Ebola vaccines and four COVID-19 vaccines.

  • Revenue from viral vector vaccines for adults accounted for a market share of 64.5% in 2022.
  • Sales of viral vector vaccines accounted for 1.7% share of the global vaccines market in 2022.

The Ebola virus can cause a severe and often deadly illness, which is referred to as Ebola virus disease (EVD). Since the first outbreak was reported in 1976, it has been a top priority to create an effective Ebola vaccine. The use of viral vector vaccines has emerged as a promising approach in the development of an Ebola vaccine. This market has experienced significant growth in recent years, mainly attributed to the rising incidence of Ebola virus disease (EVD) in Africa and other regions worldwide. Increased government and private sector investments in the research and production of Ebola vaccines are also fueling market growth.

Viral vector vaccines have demonstrated high efficacy rates in preventing infectious diseases, which has boosted demand for this type of vaccine.

What are the Factors Influencing the Demand for Viral Vector Vaccines?

Rising Incidence of Infectious Diseases across the World

Increasing prevalence of infectious diseases, such as Ebola, Zika, and HIV, has necessitated the creation of more effective vaccines, which is boosting demand for viral vector vaccines. Emergence of pandemic-level diseases has led to increased procurement of vaccines by international organizations such as UNICEF.

UNICEF is working with national governments to ensure that countries can access affordable and high-quality vaccines in a timely manner. UNICEF is working on several initiatives to strengthen vaccine procurement to control the increasing spread of infectious diseases around the world. This is one of the key drivers of the viral vector vaccines market and will have a positive impact on the growth of this market in the coming future.

  • The need for Ebola vaccines will increase in the next few years, both during outbreaks and between them, according to a WHO press release from 2019.

To satisfy this demand and ensure vaccine security, WHO is partnering with Global Alliance for Vaccine and Immunization, UNICEF, and others to develop a Global Ebola Vaccines Security Plan. This will require an enhanced capability for the supply of such vaccines and an increase in the number of manufacturers. This would eventually have a favorable effect on the market.

Government and non-government bodies are focusing on immunization campaigns to raise public awareness of vaccinations.

  • In 2018, UNICEF issued a press release stating that, since the onset of the Ebola outbreak in the Democratic Republic of the Congo (DRC), the organization and its partners have disseminated vital information on how to prevent contracting the lethal virus to over 300,000 individuals. Additionally, it conducted awareness campaigns for more than 800,000 people residing in the affected regions.

How is Viral Vector Vaccines Market Growth Being Restricted to Some Extent?

“Vaccination Hesitancy among Public and Stringent Safety Regulations”

Coordination among scientists, physicians, public health officials, industry and vaccine developers, and society is required for the development of new vaccines, which is a lengthy, methodical, expensive, and time-consuming process. To develop safe and effective vaccines that are widely used, these stakeholders must work together to overcome the aforementioned hurdles. The high cost of vaccine development is one of the biggest challenges experienced by several vaccine manufacturers. It costs about US$ 700 million to US$ 1 billion to develop a vaccine.

Vaccination hesitancy, rigorous safety regulations, societal demands for complete efficacy, rising requirements for single-dose efficacy, the urgency to respond promptly to global outbreaks, the limited number of vaccine manufacturers, the need for more complex vaccines to combat current pathogens, the low efficacy of some licensed vaccines, and the variability in the correlation between humoral immune responses and protection are among the common challenges faced in vaccine development. These challenges can impede the growth of the global market.
