Kissing is allowed during rabies vaccination. The reason for this doubt is that there is a fear that during the rabies vaccination period, when you are in the incubation period of rabies, kissing at this time may transmit rabies to others through saliva. However, this is theoretically impossible, and no examples of rabies transmission from person to person have been found from actual examples, so there is nothing to worry about. Because rabies virus is not present in the central nervous system, peripheral nervous system, or muscles when the rabies virus infects the body, it is not present in saliva, so rabies cannot be transmitted through saliva. Human-to-human transmission of rabies is theoretically possible only at the onset of rabies, when the rabies virus is present in saliva.
