There is no information specifically stating that chocolate should not be eaten during the rabies vaccination. Chocolate also significantly affects the immune effect of the rabies vaccine and does not significantly affect the amount of rabies neutralizing antibodies produced by the rabies vaccine, nor does it have a significant effect on the duration of the vaccine. However, because chocolate, like strong tea and coffee, has the potential to affect sleep and cause sleeplessness, it is not recommended. It is important to rest during the rabies vaccination and try not to eat anything that interferes with sleep. Some people may also have adverse digestive reactions such as nausea and bloating as a result of the rabies vaccination. If you eat more chocolate at this time, there is a possibility that it may aggravate the adverse symptoms in the digestive tract because it is not good for digestion. Therefore, from the above two aspects, it is considered less suitable to eat chocolate.
