The World Health Organization has granted prequalification to a new oral polio vaccine type 2. This step confirmed that it will support efforts to eradicate the disease. The vaccine is a crucial tool in the global campaign to eliminate polio, which still persists in some regions of the world. Prequalification means the vaccine meets stringent safety and efficacy standards. The WHO stated that this vaccine will help strengthen population immunity, especially in areas at high risk of virus transmission.
