After the fourth dose of rabies vaccine, one more dose is needed to complete the vaccination. Although smoking does not affect the effectiveness of the vaccine, it is not recommended because, as we all know, smoking is harmful to lung health. After four doses of the rabies vaccine, the body should have produced a certain amount of antibodies to the rabies virus, and there are no studies suggesting that lifestyle habits or diet affect the effectiveness of the rabies vaccine. The rabies vaccine works by stimulating the body’s immune system to produce antibodies against the rabies virus. The cells that function are mainly B lymphocytes, so it is recommended to maintain a normal, healthy lifestyle throughout the five doses of the rabies vaccine to be able to produce effective antibodies against the virus.
