Glaxo aims to position Streptorix as an improvement on
Wyeth's Prevnar and plans to submit the product for regulatory
approval in Europe in 2007. It has not given a filing date for
the United States.
Europe's biggest drug maker said last year it believed
Streptorix could help more than double the global market for
vaccines against Streptococcus pneumoniae to 1.25 billion to
1.75 billion pounds ($2.2 billion to $3.1 billion) by 2010 from
600 million pounds in 2004.
