There is no need to be particularly concerned if you have had a rabies vaccination or if you have had alcohol during the injection. Although drinking alcohol may cause a decrease in the effectiveness of the rabies vaccine, it does not cause a complete loss of the vaccine’s effectiveness. In the future, you should not drink alcohol during the rabies vaccination, but wait until you are completely finished with the rabies vaccine, and the rabies vaccination should still be completed in the same way and at the same time as the previous injection. If you drink a lot of alcohol during the rabies vaccination, you cannot prevent the rabies vaccination from being given in the same way as before. If you are particularly concerned about the effect of alcohol on the rabies vaccine, you can have your rabies neutralizing antibody levels tested a few days or weeks after the rabies vaccination.
