This vaccine is imperative because even though most cases of chickenpox are mild, this highly contagious virus can cause serious complications such as severe skin infections that sometimes leave permanent scars, pneumonia, inflammation of the kidneys, arthritis, or rarely brain infection or even death. Patients who have chickenpox are predisposed to skin and even bloodstream infection with group A Streptococcus (GAS) and Staphylococcus aureus bacteria, which can be life threatening.Chickenpox is more likely to be severe in adolescents and adults and in anyone who has an abnormal immune system or is taking medicines that affect the immune system. Pregnant women who get chickenpox for the first time may develop severe illness themselves or may miscarry. There may be abnormalities in the fetus, such as congenital varicella syndrome (limb, scarring, eye damage, even blindness, brain damage). Even when people recover from chickenpox, painful shingles can develop later in life.Prevention is the key to not contracting chickenpox, and the most effective preventive method is vaccination.
Some people should not receive the chickenpox vaccine including:
The varicella vaccine was first recommended for routine use in the United States in 1995. In 2006, a combination vaccine called MMRV that combines varicella with measles, mumps and rubella (MMR) was licensed for use in the United States for children from 1 to 12 years of age. However, in 2008 became unavailable because of production problem.
Chickenpox is caused by a highly contagious virus and is easily spread by direct person-to-person contact or rarely by airborne contact. Patients with chickenpox are contagious until the rash has crusted over completely.
This vaccine has been proven to be effective in at least 90 percent of children and adolescents who receive two doses. Anyone who contracts chickenpox after having been vaccinated usually develops a much milder form of the disease.In June 2006, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices recommended that all children, adolescents and adults receive a total of two doses of varicella vaccine to achieve optimal protection.
The first dose should be given to infants between 12 and 15 months of age and the second dose between 4 and 6 years of age.Children, teens and adults who have not had chickenpox or were not vaccinated against the disease should receive two doses of varicella vaccine at least 4 to 8 weeks apart.Review the vaccination schedule for those who start late on a vaccine or are more than one month behind.
The majority of patients who receive the chickenpox vaccine have no side effects.Mild side effects may include:
A rare side effect of this vaccine is seizure brought on by a high fever or pneumonia.
Because varicella is a live, weakened virus, about 1 percent of those who receive this vaccine will develop a chickenpox rash, which is a significantly milder form of chickenpox than if it develops naturally.
The best person to ask about this or any vaccine is your child’s pediatrician or your primary health care provider. Your provider can answer your questions and give you more information on the chickenpox vaccine.Immunization is the best thing you can do for your child and yourself to protectagainst chickenpox.
