Just a thought
Do you know how the immune system works?
In very simple unscientific terms (appologies this is written for a child to understand) the human body has a number of foot soldiers that search out and destroy bad things in our bodies. Bad things include some bacterias and some viruses.
When we are ill the bad things are in battle with soldiers. Each disease has its own particular way of attacking. Once there has been an attack the soldiers learn how to combat it and can teach new recruits how to do the same.
vaccination / innoculation does one of two things. It either mounts a fake attack / training exercise or it mounts a small attack that causes minimal disease, both these thing train the soldiers how to react if they come accross it again.
As well as vaccination given in a medical setting, the human body is exposed to natural attacks that may cause illness but may also act as a training exercise.
So you cannot stop your child from comming into contact with bacteria and viruses, some of which will attack your child.
Different populations have different endemic disease, ie the disease is always around, there is always someone with it and it passed from one person to another without everyone getting ill at the same time.
When a disease is endemic your child will either
a) not have come into contact with it yet
b) have come into contact with it and developed an immune response
c) come into contact with it and be ill
a - will not happen forever
b - you can partially control
c - you can partially control
The descisions I have made about my own vaccinations (as an adult) is based on the above.
Is the disease I am considering vaccinating against endemic? If it is not then there is little point vaccinating eg small pox and rabbies - the former has been erradicated and the second is not endemic in the UK. I worked in a healthcare setting with TB patients, so for my personal enviroment TB was endemic so I not only had BCG but was tested to make sure it was working.
OK, so assuming something is endemic and I will, sooner or later, come into contact with it. Also assuming I have no medical condition that will affect the vaccination / my health.
If I'm vaccinated I will be exposed to it directly (live vaccine) or something that creates the same response. As it is (usually) an injection it will also contain some other chemicals, it may have been grown in eggs. Am I happy about the other ingredients going into my body?
As a result if I come into contact with it in a 'natural' enviroment after that my body will know what to do to fight it.
If I'm not vaccinated then I may still just develop an immune response if I come in contact with it, or I may develop the disease. What are the effects of the disease? More importantly what about any complications?
eg Polio is usually a very mild infection, most people who have had polio don't even know they had the disease as it causes no symptoms for most people. However if it enters the central nervous system it can lead to paralysis. Talk to people in their 70s and they all have horror stories.
In the end it is down to you and your DP. In adults flu vaccine is recomended for certain groups because for them flu can kill.
For people with healthy immune systems and with no other factors such as asthma it is not recomended because
a) it doesn't kill
b) having flu gives you immunity for three years, a flu jab just for one season.
In certain parts of the country many children are not vaccinated aganist certain diseases and they are becoming prevelant, so your own, and your child's exposure is higher. Your child will have higher exposure when he/she starts interacting with other children such as at nursery.
Remember this does not have to be all or nothing, you can look at each vaccine / disease individually. Is it endemic in my child's enviroment? How easy is it to catch? What are the complictions if any of the disease / vaccine? What treatment(s) are available for the disease?
As stated before I'm pro vaccine but it is really up to you and DP. But I have to say the worst reason for not vacinating came from a neighbour who wouldn't vaccinate because it would make the baby cry. IMHO not a good enough reason.
