Why do vets want to give jabs yearly?

What is vaccination

Jabs are yearly because of the way the immune system works. There are two levels of response, the passive (protection by skin), and the active (which is where the body makes the antibodies).

If you think of it like a army, the passive is like
a border with sentry towers, and the active would be the battilions within the fort protecting the capital. When the sentry spots an enemy it sends a message to the fort asking for reinforcements (antibodies), but this takes a few day for them to arrive as they have to be trained and equipped first. In this time the enemy overwhelms the sentry’s and invades the country.

Now what a jab does is to “present” some enemy to this sentry so that it sends the message to the fort to ask for reinforcements. But with the jab their is no risk of invasion so the body has time to create the reinforcements (antibodies). Now these antibodies are there and sit in the fort trained and equiped ready to respond, instead of taking a few days to arrive to back up the sentry, they arrive much faster so the enemy is destroyed sooner.

However just like in a human army, without training they would get bored, desert, quit so that over time the number waiting to respond falls to a level where they would not be able to defeat the enemy. This is why yearly jabs are given to “train” this response and keep it at a effective level.

The drug companies have done research counting the number of antibodies over time and the effective number and based on this calculated the time the jab needs to be given. It is possible for a vet to do a titer-count to check an animals number of antibodies to see if the vaccine is needed – BUT this test costs more than the vaccine and if it is low the vaccine still needs to be given.
