Quinvaxem is a pentavalent vaccine, a conjugation of five individual vaccines in one, that protects children in infancy from diphtheria, tetanus, pertussis (whooping cough), hepatitis B and ''Haemophilus influenzae'' type b (a bacteria that causes meningitis, pneumonia and otitis).〔(【引用サイトリンク】title=Immunisation and Pentavalent Vaccine )〕 In March 2006, the Korea Food and Drug Administration (KFDA) awarded licensure to Quinvaxem. The vaccine was being produced by Crucell in Korea and was co-developed along with Chiron Corporation (that was eventually acquired by Novartis International AG on April 20, 2006), which supplies (''in bulk'') four out of the five vaccine components. Mid-2010, Crucell had procured an order worth US$110 million from UNICEF for the distribution of the Quinvaxem Vaccine for free to many of the developing nations. This order brought the total revenue from Quinvaxem alone to US$910 million for Crucell since its initial launch in 2006. In 2012, UNICEF and the World Health Organization had issued and recommended a joint statement to the Immunization Division, Ministry of Health and Family Welfare, Government of India and other developing nations in separate documents about the use of Pentavalent vaccines for the prevention of the 5 leading diseases responsible for death in children.〔(【引用サイトリンク】title=Pentavalent Vaccine )〕 In 2014 South Sudan became the last of the 73 GAVI-supported countries 〔(【引用サイトリンク】title=With GAVI support, pentavalent vaccine is available in the 73 poorest countries )〕 to introduce the five-in-one vaccine, which was first launched in Guyana in 2001. Its main competitor is the vaccine Pentavac manufactured by the Serum Institute of India and by Sanofi Pasteur MSD.〔(【引用サイトリンク】title=List of vaccines )〕〔(【引用サイトリンク】title=Serum Institute of India vaccines )〕 Another competing vaccine - Easyfive, produced by Panacea Biotec was removed from the WHO's list of pre-approved and prequalified vaccines in mid-2011〔(【引用サイトリンク】title=Pentavalent vaccine, Easyfive, removed from WHO list of prequalified vaccines )〕 ==Vaccine composition and side effects== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quinvaxem」の詳細全文を読む スポンサード リンク
