Live Attenuated Vaccines Market Size

Live Attenuated Vaccines Market Size

Live Attenuated Vaccines Market size was valued at USD 14.5 billion in 2023 and is expected to reach USD 35.6 billion by 2032 growing at a CAGR of 10.4% over the analysis period, due to the increasing incidences of viral and bacterial infections worldwide along with growing emphasis on vaccination as a preventive measure.

According to the World Health Organization (WHO), the estimated number of people who fell ill with tuberculosis worldwide in 2022 increased to 10.6 million, up from 10.3 million in 2021 and 10.0 million in 2020. The rise in tuberculosis cases highlighted the ongoing challenges in combating this infectious disease and emphasized the need for intensified efforts in prevention, diagnosis, and treatment to address this concerning global health issue. This demand surge, coupled with advancements in vaccine development and distribution infrastructure, has further accelerated market growth.
 

Live attenuated vaccines are a type of vaccine composed of weakened forms of pathogens, typically viruses or bacteria, which are capable of replicating within the body but are attenuated or weakened to a degree that they cause minimal or no disease symptoms. These vaccines stimulate a robust immune response by mimicking natural infections, leading to the production of memory cells that provide long-lasting immunity against the targeted pathogen.
