Babies, honey, botulism and vaccines

About Infant Botulism
Infant botulism can occur when a child ingests Clostridium botulinum bacteria, which are found in dirt and dust and can contaminate honey.

These bacteria are typically harmless to older children and adults because their mature digestive systems can move the bacteria through the body before they cause any harm.

But very young babies haven't developed the ability to handle the bacteria yet. So once an infant ingests them, the bacteria can produce a toxin. That toxin interferes with the normal interaction between the muscles and nerves and can hamper an infant's ability to move, eat, and breathe.

I don't understand how babies do not have mature enough digestive systems to handle botulism and yet they are supposed to easily handle all those vaccines they pump into them before they are a year old.
