Which vaccine is available in oral form?

The vaccine available in oral form is the Rotavirus vaccine. This vaccine is specifically designed to protect infants and young children against rotavirus infections, which can lead to severe diarrhea, dehydration, and hospitalization. The oral form is advantageous because it allows for easier administration, especially for infants who may have difficulty with injections.

In contrast, the other vaccines mentioned are delivered through injection. For example, the MMR vaccine (measles, mumps, and rubella) is given through subcutaneous injection to ensure adequate immune response. Similarly, the Hepatitis B vaccine is administered intramuscularly, which is the standard route for most vaccines that require a more robust response. The Varicella vaccine, which protects against chickenpox, is also given via injection to ensure it is effective. Oral vaccines like Rotavirus are less common, making Rotavirus distinct in this context.
