The best way to prevent chickenpox is to get the chickenpox vaccine. Children, adolescents, and adults should get two doses of chickenpox vaccine. Chickenpox vaccine is very safe and effective at preventing the disease. Most people who get the vaccine will not get chickenpox.
Ask your doctor about the varicella vaccine if you're considering pregnancy and haven't already had chickenpox or been immunized. Though the vaccine is safe for adults, it's recommended that you wait until three months after your second dose before trying to conceive. If you're not sure whether you're immune to varicella, ask your doctor to perform a blood test. The test can determine whether you have antibodies to the virus. There's also a vaccine for VZV, but it's only been approved for use in adults over age 50. It's important to avoid those with chickenpox, including daycare centers and school settings, where children may not be vaccinated, and often exposed.
Test Method 1 : Whole infected cell (wc) ELISA is the most commonly used test to determine if a person has antibodies to VZV from past varicella disease. Wc ELISA is done on blood samples. It can readily detect seroconversion to a natural infection with VZV
