According to the World Health Organization, vaccination has dramatically reduced the incidence of tetanus, a severe disease caused by the bacterium *Clostridium tetani*. While a strong immune system is beneficial for overall health, no scientific evidence suggests that specific supplements prevent tetanus; the only reliable method is immunization.

A single course of broad-spectrum antibiotics can alter the gut microbiome for up to a year, wiping out beneficial bacteria alongside the harmful ones. This creates a window of vulnerability where opportunistic bacteria, including *Clostridioides difficile* (*C. diff*), can proliferate. Understanding **what to eat while on antibiotics to prevent C. diff** can be a powerful tool for protecting your gut health and minimizing this risk.

Studies confirm that inadequate micronutrient intake is a critical public health issue, with research pointing toward a strong link between specific nutrient deficiencies and an increased risk of illness. To answer the question of **which vitamin deficiency causes bacterial infections?**, research has consistently highlighted the crucial role of vitamin D in maintaining a robust immune response against bacterial invaders.
