A healthy immune system can defeat invading pathogens, where two bacteria that cause gonorrhea are no match for the large phagocyte, called a neutrophil, that engulfs and kills them. Following general good-health guidelines is the single best step you can take toward naturally keeping your immune system strong and healthy. Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these;-
- Exercise regularly.
- Eat a diet high in fruits and vegetables.
- Maintain a healthy weight
- Get adequate sleep
- wash your hands frequently and cooking meats thoroughly.
- Try to minimize stress.

A reduction in immune response to infections has been demonstrated by older people’s response to vaccines. For example, studies of influenza vaccines have shown that for people over age 65, the vaccine is much less effective compared to healthy children
