Varivax
Varivax (pronounced: vair-ih-vaks) is a vaccine used to prevent chickenpox, a highly contagious disease caused by the varicella-zoster virus.
Etymology
The term "Varivax" is derived from the words "varicella" (the medical term for chickenpox) and "vax" (a common abbreviation for vaccine).
Usage
Varivax is administered as an injection, usually given in two doses. The first dose is typically given when the child is between 12 and 15 months old. The second dose is usually given between the ages of 4 and 6 years. However, older children and adults who have not had chickenpox or received the vaccine can also receive Varivax.
Effectiveness
Varivax is highly effective at preventing chickenpox. Studies have shown that 9 out of 10 people who get the vaccine will not get chickenpox. If a vaccinated person does get chickenpox, it is usually a very mild case.
Side Effects
Like all vaccines, Varivax can cause side effects. The most common side effects are mild and include pain and swelling at the injection site, fever, and mild rash. Serious side effects are rare but can include severe rash, high fever, seizures, and pneumonia.
