What else can I help you with?
Does active immunity involve a person becoming immune to a pathogen as a result of having a disease?
by vaccination
Which person most likely will fail to develop active immunity following vaccination?
hepatitis B immune globulin 2 months ago and MMR vaccine given today
What does a positive HBS antibody titer mean?
A positive HBs antibody titer indicates that an individual has developed antibodies against the hepatitis B virus, typically as a result of vaccination or past infection. This suggests that the person has immunity to hepatitis B and is less likely to contract the virus. It is an important marker for assessing immunity status in individuals, especially those at risk for hepatitis B exposure.
Why should booster vaccination be given?
Booster vaccinations are given to stimulate the immune response and allow an animal or person to have continued immunity without having to go through the whole vaccination process again.
What does HBsAg reactive but HbsAb is negative means?
HBsAg reactive means the person has been infected with Hepatitis B virus. HbsAb negative indicates that the person does not have immunity against Hepatitis B. This combination suggests an active Hepatitis B infection without immunity.
What is HBSAG?
HBSAG, or Hepatitis B Surface Antigen, is a protein on the surface of the Hepatitis B virus (HBV) that indicates active infection. The presence of HBSAG in the blood suggests that a person is currently infected with HBV and can potentially transmit the virus to others. Testing for HBSAG is crucial for diagnosing Hepatitis B and determining the appropriate management and treatment strategies. If HBSAG is negative, it may indicate either past infection or immunity due to vaccination.
Possibility of getting hepatitis b after vaccination?
If a person is infected with Hepatitis B, the vaccine will have no effect. The vaccine contains proteins from the virus, and these are already present in the person's body, and the immune system has already responded to them.
What is non-reactive of hepatitic B?
Non-reactive for hepatitis B typically refers to a negative test result for hepatitis B surface antigens (HBsAg), indicating that a person is not currently infected with the virus. It can also refer to the absence of antibodies to hepatitis B surface antigen (anti-HBs), suggesting that the individual has not been vaccinated or previously infected. In both cases, further testing may be needed to determine immunity status or the need for vaccination.
What will happen if anti-HBs is reactive?
If anti-HBs is reactive, it indicates that the person is immune to the hepatitis B virus either due to vaccination or a past infection. This means that the person has developed antibodies against the hepatitis B surface antigen, providing protection against future hepatitis B infections.
How long does rubella titer stay in the body?
Rubella titers, which indicate immunity to the rubella virus, can remain detectable in the body for many years after vaccination or infection. However, the exact duration can vary from person to person. Generally, after vaccination, immunity is considered to last for at least 10 to 20 years, but some individuals may retain protective titers for life. Regular testing may be recommended for certain populations, such as pregnant women or healthcare workers, to ensure continued immunity.
A positive tuberculin skin test shows cellular immunity to Mycobacterium tuberculosis How could a person acquire this immunity?
having the actual disease
The process of vaccination?
Vaccination is the process of attempting to confer artificial immunity on an individual organism by exposing the immune system to antigens of the pathogen being vaccinated against. Vaccination does not provide nearly as good protection as natural, or acquired immunity.
