You can have a normal diet after the rabies vaccination, and of course you can drink milk tea. This is because there is no scientific study that proves that diet can affect the effectiveness of the rabies vaccine. The rabies vaccination helps the body to produce enough rabies immunoglobulin to protect against the rabies virus. The source of immunoglobulins is mainly protein, so a balanced high protein diet is needed to be able to promote the production of antibodies. Milk tea can certainly be consumed, but it has no role or effect on the vaccine. It takes one month to complete the rabies vaccination, with a total of five doses, and regular vaccination is effective against rabies virus infection.
