As of 2015, no approved shot is available to help people quit smoking, according to the Centers for Disease Control and Prevention. Researchers are conducting clinical studies to develop a vaccine to help people quit smoking, but no vaccine is approved yet.
Clinical trials to develop a vaccine and ensure that is it both safe and effective can take several years, according to the CDC.
Researchers are focusing on developing a vaccine that causes the production of antibodies in the smokers body to help smokers quit smoking. According to the CDC, smokers should not trust clinics that are currently administering vaccines to help individuals quit smoking.
