LINE Plus Corporation, the Korea-based subsidiary of LINE Corporation, earlier this year entered into a memorandum of understanding (MOU) with IVI. In addition to raising funds through the BT21 sticker set, the collaboration is leveraging LINE’s reach as a global mobile platform to promote the use of vaccines and increase rates of immunization around the world and give users access to reliable information about infectious diseases and vaccinations through an IVI Official Account (OA) in Indonesian, Thai and English.


An initiative of the United Nations Development Programme (UNDP), IVI is a non-profit international organization dedicated to vaccine research, development and delivery. The institute developed and completed tech transfer for the world’s first affordable oral cholera vaccine, entered phase III clinical trials for a novel typhoid conjugate vaccine, and recently announced that they will conduct a Phase I/II clinical trial for a new COVID-19 vaccine.


LINE has been implementing a variety of initiatives in response to the COVID-19 pandemic, and the agreement with IVI represents one more way LINE is bringing people closer to the information and services they need.
