In a study published last year, more than 20,000 parents were surveyed in 2009 on their adolescent's immunization status for three vaccines: tetanus/diphtheria or tetatnus/diphtheria/pertussis (Td/Tdap), tetravalent
meningitis (MenACWY) and human papillomavirus (HPV).
Meningococcal polysaccharide vaccines are available in either bivalent (groups A and C), trivalent (groups A, C and W), or tetravalent
(groups A, C, Y and W135) forms to control the disease.
Later in 2006 GAVI introduced tetravalent
