Vaccines are necessary for children to grow up healthy and strong.
Research has come a long way in the past years, saving millions of lives with the development of new vaccines. The vaccine being tested is indicated to protect against invasive disease caused by Haemophilus influenzae type b and against infection caused by all known subtypes of the hepatitis B virus. Since 1996, when the vaccine was first licensed, approximately 3.4 million doses have been sold. Generally, it has shown to be well tolerated. Healthy infants who are between 6-7 weeks of age may qualify to participate in this no cost research study.
