Information for patients: Thimerosal & vaccines
Thimerosal is used as a preservative in some multi-dose vials of vaccines to prevent contamination. Preservatives are not required for vaccines in single-dose vials. As a preservative, thimerosal is added at the end of the production process to the bulk or final container to prevent contamination after multi-dose vials are opened. Today, all routinely recommended licensed pediatric vaccines that are currently being manufactured for the U.S. market are free of thimerosal as a preservative. Thimerosal still may be used in the early stages of manufacturing of certain vaccines, but is removed through a purification process, with only trace, or insignificant, amounts remaining. more


Prevention of varicella updated recommendations of the Advisory Committee on Immunization Practices (ACIP)
In February 1999, the Advisory Committee on Immunization Practices (ACIP) expanded recommendations for varicella (chickenpox) vaccine to promote wider use of the vaccine for susceptible children and adults. The updated recommendations include establishing child care and school entry requirements, use of the vaccine following exposure and for outbreak control, use of the vaccine for some children infected with the human immunodeficiency virus (HIV), and vaccination of adults and adolescents at high risk for exposure.  more

Information for health care workers: The varicella vaccine -- FAQs
ACIP recommends that all health care workers ensure that they are immune to varicella, since nosocomial transmission of varicella is well-recognized. Varicella immunization is particularly recommended for susceptible health care workers who have close contact with persons at high risk for serious complications, including a) premature infants born to susceptible mothers, b) infants who are born at < 28 weeks of gestation or who weigh < 1,000 g at birth (regardless of maternal immune status), c) pregnant women and d) immunocompromised persons. more

The Herpevac (R) (herpes vaccine) trial for women
There are many benefits to volunteering to participate in a clinical trial. Participants gain access to new research developments before they are widely available and help others by contributing to medical research. Carefully conducted clinical trials, such as this one, are the fastest and safest way to find treatments that work in preventing or treating disease. The Herpevac Trial for Women is leading the way in the development of vaccine that may protect women against the risks associated with genital herpes. As such, it may be a major medical breakthrough that could help millions of people.  more
