Suffered from chicken pox 3weeks ago.All blister crusted over.Is it possible to still develop chicken pox again after 3 weeks.Symptons dizziness tired?

This is seen on testing as a mild hepatitis and irritation of the central nervous system. Report any progressive symptoms or new fever to your doc. ...Read more

Can you get chicken poxs from the chicken pox vaccine ?

Can you get chicken poxs from the chicken pox vaccine ?

Shot reaction: A percentage of the vaccine recipients may breakout with atypical chickenpox, which is not the same as wild disease.

Chicken pox effects during sixth month of pregnancy.Does it effects baby?

If you get chicken pox during first or second trimester of pregnancy, there's a slight risk (less than 2 percent overall) that your baby will get something called congenital varicella syndrome. The risk is highest (about 2 percent) if you're infected between 13 and 20 weeks' gestation. At 6 mos. Virtually no risk. ...Read more

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.

Time will tell if future boosters are needed but with 30+ years of worldwide data it looks good. ...Read more

If you have chicken pox during early pregnancy, is your baby then immune to chicken pox?

If you have chicken pox during early pregnancy, is your baby then immune to chicken pox?

No.: Early in pregnancy (first 3 months), there is very little chance that the fetus will develop chickenpox, and even then, fetuses don't have an immune system yet and can't develop immunity. Chickenpox later in pregnancy can be serious business, however. Even if you're early, you need to inform your obstetrician, who may wish to treat you with Acyclovir even though risks at that stage are small. ...Read more
