Does the chicken pox vaccine confer lifelong immunity?

Does the chicken pox vaccine confer lifelong immunity?

Possibly: Introduced in the late 70's in japan, the current CP vaccine was not adopted in the us until the 90's. There are good data that one dose removes the risk of death with cp, but likely only 85% get protective immunity from 1 dose, with that improving to >95% after 2 doses given at least a month apart. Time will tell if future boosters are needed but with 30+ years of worldwide data it looks good. ...Read more

If you have come in contact with someone suffering an outbreak of shingles, you have been exposed also. Your doctor can give you varicella zoster immune globulin (VZIG) to prevent infection ...Read more

Antibodies for varicella zoster IgG positive, and varicella IgM negative, means immunity for shingles or just for chicken pox?

Both: Varicella and zoster are the same virus. Chickenpox occurs with the first exposure to the virus and zoster is the re-activation of the virus that has been lying dormant in the body as a result of some significant stress to the body. ...Read more

Shingles vaccine needed in suppressed immune systems?

Contraindicated: Shingles vaccine (zostavax) is a live attenuated vaccine that contains a pretty good dose of weakened chicken pox virus. It is not recommended in people who are immunosuppressed due to risk of infection arising from the vaccine. ...Read more

Does chickenpox vaccine protect from shingles?

Does chickenpox vaccine protect from shingles?

Maybe,maybe not: The vaccine developed to help suppress shingles has many times the amount of varicella material than the chickenpox vaccine. Simple varicella vaccine use may res-erect some of your waning varicella antibodies and put off shingles but it may just protect you better against wild chickenpox. ...Read more

VZV IgG titer= 1926, VZV IgM titer >3.91 with reactivated shingles present. What does test mean? Active VZV infection? Is 1926 dangerously high.

VZV IgG titer= 1926, VZV IgM titer >3.91 with  reactivated shingles present. What does  test mean? Active VZV infection? Is  1926 dangerously high.

No it just means: You had chickenpox previously. It is not dangerous at all . The IGm is what tell that you have reactivated and then it is called shingles. You can't have shingles if you did not have chickenpox before. ...Read more

Immune to rubella, measles, mumps if you've had vaccines 2x before age six?

Mostly: Although vaccines are safe and effective, there is an occasional peron whose immune system does not respond well to the recommended series. Thus they are not immune. If needed, blood tests can measure this. Still worth immunizing to maximize protection. ...Read more

Prevnar (pneumococcal vaccine) 13 vaccine has diphtheria proteins in it. Does Prevnar (pneumococcal vaccine) 13 vaccine protect against pneumococcus and diphtheria? Thank-you!

Prevnar (pneumococcal vaccine) 13 vaccine has diphtheria proteins in it.  Does Prevnar (pneumococcal vaccine) 13 vaccine protect against pneumococcus and diphtheria?  Thank-you!

No: The diphtheria proteins used for PCV-13 (Prevnar) are not antigenic for diphtheria. That means they are not recognized by the body to produce an immune response. They just help carry the pneumococcal proteins into the appropriate cells to create the immune response for the pneumococcal bacteria. ...Read more

Booster antigen can be neuterlized by antibody produced against previous vaccine, true?

Booster antigen can be neuterlized by antibody produced against previous vaccine, true?

Unlikely: The booster antigen (vaccine) is used to stimulate your body to produce more antibody often up to several-folds. By the time you need a booster, there is usually marginal quantity of antibody against that antigen to bind it. Even if the antigen is bound by the antibody, the body may still recognize the complex as an antigen. Although theoretically possible, the effect would be minimal ...Read more

Can chicken pox from the vaccine (against chicken pox)?

Yes and no: A small percentage of vaccine recipients can and do break out a week or more after varicella vaccination.This is not the wild chickenpox but a manifestation of the weakened vaccine virus.
