How to Sign "Vaccination"
To sign 'vaccination', form a '3' handshape with your dominant hand by extending your thumb, index, and middle fingers. Bring your hand to your non-dominant upper arm and tap the tips of your index and middle fingers against the side of your arm, mimicking an injection. Note: The video also includes additional signs to explain the broader concept of immunization, but the tap to the arm is the core sign for 'vaccination'.
