Vaccines are biologically manufactured medications that provide active acquired immunity to illnesses such as cholera, polio, rotavirus, smallpox, and yellow fever. A vaccination is made up of an agent that is similar to the disease-causing bacteria. Vaccines are typically made using live, attenuated, or dead forms of the disease-causing bacterium, its toxins, or surface proteins.
Infections such as cholera, tuberculosis, and others are projected to drive growth in the oral vaccination market over the forecast period. According to the World Health Organization (WHO), around 1.3 million to 4.0 million cases of cholera and approximately 10 million cases of tuberculosis were reported globally in 2018.
Moreover, increasing government support towards new product approvals are expected to drive the oral vaccines market growth. For instance, in October 2018, Sanofi Pasteur received the prequalification status from the World Health Organization (WHO) for its inactivated Polio Vaccine (IPV), ShanIPV. The prequalification program ensures that the vaccines are safe and effective for the immunization programs. The prequalification status qualifies the vaccine ShanIPV for purchase by the agencies of the United Nations for various immunization programs.
North America held the biggest market share in 2018, owing to the region's development of new technologies for improving vaccine utility. For example, according to the American Chemical Society (ACS) journal Nano Letters, researchers developed oral vaccinations combined with micromotors in February 2019. To improve vaccination utility, the micromotors protect the active ingredients in the vaccines from acidic conditions in the stomach.
Asia Pacific is also expected to witness significant growth in oral vaccines market due to increasing government initiatives and various immunization campaigns. For instance, in August 2019, the United Nations International Children's Emergency Fund (UNICEF), reported that around 400,000 people including 65,000 children were vaccinated in a six day oral cholera vaccination campaign run by the local health authorities of Yemen in three cities of Yemen (Aden, Al Dhale’e, and Taizz).
