Recommendations for the chickenpox vaccine

Many pediatricians and parents are very happy with Varivax, the chickenpox vaccine.

History of the chickenpox vaccine

Although the chickenpox vaccine was first developed in Japan in 1974, it was not until 1995 that it was approved in the United States and added to the vaccination program.

Before the chickenpox vaccine was first used, chickenpox was a very common disease in childhood, which, even when it is not serious, left children miserable for at least a week. And, unfortunately, sometimes these chickenpox infections have become serious, leading to hospitalization and even death.

In the United States, in the pre-vaccine era, «there were an average of 4 million cases of chickenpox that led to 10,500-15,000 hospitalizations and 100-150 deaths each year,» many of which occurred in children. Now that Varivax is commonly used, there has been a «substantial decrease in the incidence» of chickenpox and its complications.

Vaccine history

Although it has been found that «chickenpox vaccination is very effective in preventing disease,» it is not perfect.

A single dose of Varivax has been shown to be between 71% and 100% effective in preventing chickenpox, and most children who develop a revolutionary infection (an infection after vaccination) develop a very severe case. However, the chickenpox vaccine offers over 95% protection against moderate and severe chickenpox infections, although several studies have shown 100% protection against the most severe cases of chickenpox, with over 500 lesions.

However, if they receive only one dose of vaccine, it means that many children will still get chickenpox, including some who can get moderate or severe infections.

The latest recommendations

Because of these revolutionary infections, the Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP) issued a new recommendation for a routine varicose vein booster vaccine in 2006.

Children should usually receive a second dose of chickenpox vaccine when they are between four and six years old. Older children and adults should also receive a second dose if they have not already done so.

The second dose has been shown to provide greater protection for vaccinated children.

Children may still have a very mild case of chickenpox, even after two doses, but they will probably not have a fever and will often have less than 50 chickenpox lesions.

What you need to know about the chickenpox vaccine

The chickenpox vaccine is a live vaccine that is generally well tolerated by most children. Other things to know about the chickenpox vaccine include:

  • The first dose of chickenpox vaccine is given when young children are in between 12 and 15 months old.
  • The second dose of chickenpox vaccine can be given at any time, as long as at least three months have passed since the first dose.
  • The chickenpox vaccine can help prevent chickenpox if given to a susceptible person (who has not had a natural chickenpox infection and has not been vaccinated) within three to five days of exposure to someone with chickenpox.
  • The chickenpox vaccine does not cause an increase in cases of Shingles not a shingles epidemic. This is just another anti-vaccine myth that is used to scare parents from vaccinating their children and protecting them. vaccine-preventable diseases . The growing trend of adult shingles began before the U.S. chickenpox vaccine began in the United States, and the growing trend of adult shingles cases exists in other countries that do not give them. Children are commonly vaccinated against chickenpox.
