What can vaccination involve?

• Injecting a dead form of the diseases to stimulate immunity 
• Injecting an inactive form of the disease to stumulate immunity.
• Injecting an inactive form of the pathogen to stimulate immunity. 
• All of the above

There is no vaccine against the common cold because:

• Colds are caused by bacteria so we can use antibiotics to treat them.
• The cold virus mutates too quickly for a vaccine to be effective
• Colds are not usually serious enough for it to be worthwhile to develop a vaccine.
• Colds are not infectious so it doesn't matter.
