A dead or very weak form of the disease.
Antibodies.
A vaccine stimulates the body to produce antibodies against a specific disease causing pathogen. This makes the body able to fight off that disease.
it is vaccine . you get injected it before and it makes ou immune to the disease.
The reason the immune system is less effective in a person with HIV is because the virus attacks the immune system and makes it weaker.
it makes sperm cells
MMR is measles mumps and rubella. If you give a strain of measles to a child, it's immune system develops anti bodies that destroy the virus, the anti bodies will stay around for ever and the child will be immune to measles as the anti bodies will prevent the measles virus from spreading.
The immune system is compromised; which makes the person more susceptible to other infections.
No, a flu shot tricks your immune system to think you have the flu and it makes and sends antibodies to fight the infection, if you have an otherwise healthy immune system. The immune responses do not "decrease" your system's ability to protect you and actually may help you respond more quickly to the next antigen (causative organism). A flu shot just introduces a "dead" or weakened flu virus to your system so it can work out how to make antibodies against that organism in advance of a real infection by a full-strength flu virus. The immune system in healthy individuals is ready and able to go to work to fight infections, and the more organisms it works against, the more patterns for antibodies there are in your immune system "memory". Some of the old patterns may match the new organism well enough to provide protection, or make it easier for your immune system to build slight variations in them to work on the new antigen. So, exposure to more organisms may actually help prime your immune system so it can respond more quickly to any "invasion".
Pieces (or synthetic pieces) of the disease causing organism called antigens that can be recognized by the immune system as something that does not belong in the body. This prompts the immune system to produce antibodies that recognize those antigens and attack them the next time they appear, typically when challenged by the real disease causing organism.
Alcohol, drugs, smoking, poor diet, emotional stress. over training, UV and radiation, chemical exposure, excess fat, inadequate protein, calorie, vitamin, mineral or water intake In addition, the biological state of aging counteracts immune function, particularly after age of 40.
yes hand sanstizer can make your immune system weak it depresses ur body and your skin it makes your immune system weak and bored because HS is always killing the germs first
It won't hurt; the flu vaccine is non-virulent and won't lower your immune system while it makes antibodies to the influenza virus. It will still be able to fight off the Bell's Palsy virus (herpes).
