Since the use of transparent bottles for packaging blackleg vaccines was accompanied by a drastic change in pH compared to amber coloured bottles, it is suggested that the use of transparent bottles to package the vaccines should be discouraged. Also, prior to bottling, it is suggested that the pH should be adjusted to 7.7-8.0, to modulate any pH drops that may occur subsequently, during storage. ER -
