Rotavac Oral Vaccine contains active components like the Rotavirus vaccine. It is a vaccine that helps protect against rotavirus infection. Rotavirus is a highly contagious virus that can cause severe diarrhoea, vomiting, fever, and dehydration, especially in young children. This vaccine has significantly reduced the incidence of rotavirus-related hospitalisations and complications, especially severe diarrhoea and dehydration. Rotavac Oral vaccines are typically included in many countries' routine childhood immunisation schedules. The primary goal of the Rotavac vaccine is to prevent severe gastroenteritis caused by rotavirus. Widespread vaccination against rotavirus protects vaccinated children and contributes to herd immunity. It should not be used by individuals with a known hypersensitivity or allergy to it or its components.  Intussusception is a rare medical condition where one part of the intestine telescopes into another part. There is a small increased risk of intussusception following the Rotavac Oral Vaccine, particularly after the first dose. Children with severe immunodeficiency disorders, such as severe combined immunodeficiency (SCID), are generally contraindicated from receiving live attenuated vaccines like the Inj Rotavac.  In some cases, if there is household contact with a known severe immunodeficiency disorder, healthcare providers may advise against vaccinating an infant with a live attenuated vaccine like the Rotavac Oral Vaccine due to the theoretical risk of shedding the vaccine virus to the immunocompromised individual.
