Officials have culled 2.5 million birds at poultry farms in western Mexico over the past three weeks in an attempt to contain an avian flu outbreak. After importing one million vaccines from Pakistan, the farming officials said they have developed a seed-based vaccine that they will deliver to four laboratories to produce over 80 million doses initially. Officials said they have visited 148 poultry farms. Of those, bird flu was found in 31 farms, while 34 came up negative and results for the remainder were pending.
