Before then, the infections caused by the <strong>Haemophilus influenzae<\/strong> bacterium led to many deaths in children below the age of 5.<\/p>\n<p>&nbsp;<\/p>\n<p>According to WHO estimates in 2000, Hib was responsible for 8.13 million serious illnesses and approximately 371,000 deaths.<\/p>\n<p>&nbsp;<\/p>\n<p>This article dives into what <strong>Haemophilus influenzae type b vaccination<\/strong> is, the infections it protects against, and its vaccination schedule.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>What is the Haemophilus B Vaccine?<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>The <strong>Haemophilus influenzae type b vaccination<\/strong> has protected many children from infections caused by this bacterium. It is a conjugate vaccine, made from the sugar coating of the <strong>Haemophilus influenzae<\/strong> bacteria.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Haemophilus influenzae<\/strong> type b or H. Influenza is the bacterium that causes a range of infections in children under five and in adults with a weakened immune system. The bacterium primarily lives in a person&#8217;s nose and throat but can spread to other parts of the body and cause infection. While the name may suggest that it causes <strong>haemophilus flu,<\/strong> that actually is not the case.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>What Diseases are Prevented by the Haemophilus Influenzae Type B Vaccine?<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Most adults are immune to hib, and thus the mother passes on antibodies to their newborns. But they don&#8217;t last long, thereby exposing children to hib. However, the <strong>Haemophilus b vaccine<\/strong> can easily prevent them.
