! A person develops immunities thanks to the white blood cells in your blood. After an infection the body recognizes the intruder and they remember it. And when they see it they know how to stop it. Viruses change form consantly which is why people keep having colds over and over
What else can I help you with?
Is there a vaccine or immunity against Lyme disease?
Lyme disease vaccine has not been produces since 2003, but once a person is infected with a particular strain of the disease, they can develop an immunity that can last up to nine years.
What is the acquired immunity that results when a person has a disease is?
The response to infections is active or cellular immunity. Acquired immunity
How does a person become immune?
A person can become immune by being vaccinatedwhich helps the body to develop long-term immunity against a disease.
Can you develop immunity to HSV-1 after being infected?
Yes, it is possible to develop immunity to HSV-1 after being infected, but the level of immunity can vary from person to person.
Do you develop passive immunity when you receive antibodies from another person?
Yes, passive immunity is developed when you receive antibodies from another person.
Is it true that the immunity your body develops to protect you from disease is called passive immunity?
No, that is temporary immunity received from another person or from antibodies.
In what two ways can a person become immune to an infectious disease?
A person can become immune to an infectious disease through vaccination, which triggers the body's immune response to produce antibodies against the pathogen. Additionally, a person can also develop natural immunity by recovering from an infection, where the immune system creates memory cells that can recognize and fight the pathogen if re-exposed.
A person who has recovered from mumps is protected from contracting the disease by?
Active immunity.
Explain how vaccines help in combating diseases?
Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. For example, measles antibody will protect a person who is exposed to measles disease, but will have no effect if he or she is exposed to mumps. There are two types of immunity: active and passive. Active Immunity Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Exposure to the disease organism can occur through infection with the actual disease (resulting in natural immunity), or introduction of a killed or weakened form of the disease organism through vaccination (vaccine-induced immunity). Either way, if an immune person comes into contact with that disease in the future, their immune system will recognize it and immediately produce the antibodies needed to fight it. Active immunity is long-lasting, and sometimes life-long.
What benefits are there in knowing that a person may develop a disease?
Knowing someone has an increased chance to develop a disease allows you to monitor that carefully, so that if that person does indeed develop the disease, you can treat it early, or delay the onset.
What is the difference between acquired and passive immunity?
Acquired immunity is developed by the body after exposure to a pathogen or vaccine, leading to the production of antibodies. Passive immunity is temporary protection acquired through the transfer of pre-formed antibodies, such as from mother to child during pregnancy or through receiving injections of antibodies.
A positive tuberculin skin test shows cellular immunity to Mycobacterium tuberculosis How could a person acquire this immunity?
having the actual disease
