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.

A quick look at the science behind vaccinations

I wrote this earlier this even in response to a question asked on social media, it is a pretty good quick summary so thought I’d also share it here!

The science of vaccination is that it teaches the immune system to recognise the “markers” of a disease in a “controlled” manner. It takes time for the immune system to recognise and respond to a new disease. By teaching it to recognise a disease it means that the response in future is faster. From memory (I don’t have time to check exact timing atm) the first exposure to a disease takes around a week to produce an immune response to the disease, the second “booster” reduces this to a couple of days.

This is important because there are several stages in the course of a disease, and being able to recognise and start the “fight” against the disease earlier can mean a better outcome.

The problem is that in addition to the physical damage from the disease the disease also increases the stress on the body. This takes its toll and whilst the disease may not itself be fatal, the body can be simply overwhelmed from trying to deal with it. Being able to recognise the disease early before it takes hold means that a serious thing may be just a “bump” in the road.
