死疫苗:医学上称灭活疫苗,是选用能产生较强免疫性的病原体,经人工大量培养后,用理论方法灭活(杀死病原体)制成。死疫苗主要作用是诱导具有免疫力的特异抗体的产生。为了维持血清中抗体的水平,常需多次接种,注射的局部和全身的反应也较重,比如霍乱、百日咳、伤寒、狂犬病等疫苗 Dead vaccine: Medically known as inactivated vaccine, is the selection of pathogens that produce strong immunity, after a large number of artificial culture, the theoretical method of inactivation (killing pathogens) made. The main role of dead vaccine is to induce the production of immune-specific antibodies. In order to maintain the level of serum antibodies, often multiple vaccinations, injection of local and systemic reactions are also heavier, such as cholera, pertussis, typhoid fever, rabies and other vaccines
