Use Your Immune System to Prevent Flu
Looking for some ways to boost your immune system so you can prevent the flu this year? The immune system is a network that helps you avoid illness -- or sometimes it can become the underlying reason you get sick. Here are some ways to strengthen your immune system to help prevent viral and bacterial infections.
What Is the Immune System?
In simplest terms, the immune system is a balanced network of cells and organs that work together to defend you against disease. Your immune system blocks foreign proteins from getting into your body. If a few intruders happen to sneak by your biological sentry, that's OK. With a powerful "search and destroy" task force, your body deploys a host of additional immune cell forces that are designed to hunt down the unwanted intruders and ultimately work to destroy them.
How Does the Immune System Prevent Illnesses Like the Flu?
The human body has an innate ability to manufacture antibodies (proteins) that work as part of the immune system to destroy abnormal or foreign cells. Not only do these antibodies help fend off common illnesses like the flu or a cold, but they also play a role in protecting you against catastrophic diseases like cancer or heart disease.
Additionally, you also have a second protective response known as the "cell-mediated immune system." This involves immune system cells rather than antibodies. The immune system cells are "helper" or "killer" cells, and they help our body create memory of past defenses against disease.
When the body identifies a pathogen (invader) again, it immediately calls upon the memory of the previous infection and sets out to destroy the invader before the disease develops. This physiological mechanism is what lies behind vaccines or immunizations for illnesses such as measles, chicken pox, or hepatitis. When you get a flu shot or measles vaccine, you're getting a deliberate but harmless amount of the pathogen so that your immune cells can react, learn, and remember how to produce antibodies to fight the pathogen.
What Vaccines Are Recommended to Fight Disease?
According to the CDC, the recommended vaccines for children and adolescents include hepatitis A and B, rotavirus, diphtheria, tetanus and pertussis, measles, mumps, rubella, varicella, polio, pneumococcus, human papillomavirus (HPV), meningococcal, influenza, and Haemophilus influenza type B -- called HiB.
