USES: This medication is used to help prevent varicella virus infection (commonly known as chickenpox). Chickenpox is a common childhood illness, but can cause more serious illnesses in people who have not yet had either chickenpox or this vaccine. Serious (rarely fatal) problems (such as pneumonia and inflammation of the liver or brain) may rarely occur from this infection, and first-time infections in adults may be very severe. It may also cause a very serious brain/liver condition called Reyes syndrome in children or teenagers. If you are infected while pregnant, your unborn infant may be harmed. Vaccination during childhood may help prevent this infection and the problems that can occur.The virus in this vaccine is alive, but it has been weakened (attenuated) and therefore has a decreased ability to cause illness. It works by helping the body produce immunity (protection) that will prevent you from getting chickenpox, or will lessen the seriousness of the infection. As with any vaccine, it may not fully protect everyone who receives it. People who get chickenpox after getting the vaccine usually have mild cases with fewer blisters, fewer fevers, and faster recoveries.The vaccine is recommended for children 12 months and older and adults who have not had chickenpox or received a varicella vaccination before.
HOW TO USE: Read the Vaccine Information Statement available from your health care provider before receiving the vaccine. If you have any questions, ask your health care provider.This vaccine is usually given by injection under the skin by a health care professional. This vaccine should not be injected directly into a vein. When mixed, this vaccine should appear clear and colorless to pale yellow. Before giving this medication, inspect it visually for particles or discoloration. If either is present, do not use the liquid. Use the full recommended dose of the vaccine. Discard any remaining vaccine left in single-dose vials.The same dose of vaccine is used for both children and adults. Children aged 12 months to 12 years should receive 2 doses at least 3 months apart. Teenagers 13 years and older and adults who are not immune to the virus should receive 2 doses 4 to 8 weeks apart.
