Does a vaccination work straight away - i,e, are they protected then and there?

Anyone know??

I don't think so, I think it takes a few days for the vaccination to start to kick start the immune system. I think thats why things like a reaction rash can take up to a couple of weeks to come out. I know after the MMR I was told to watch for a measles like rash about 12 days after.

Plus no vaccination is 100%, and most rely on "herd immunity".

But I am no expert, I am sure someone will be along soon that is!

Thanks maryscotslass.

Anyone else know?

we just don't know how and when the body "takes" the vacc and develops immunity - you can, however be tested for immunity (privately) months later.

Thanks crushwitheyeliner (love the name by the way). So in theory you can have the MMR on Monday, play with a child who is coming down with mumps on Tuesday and still get mumps??
This would apply to all illness and vaccines would it?

The speed of the immune response will depend on the vaccination. Measles for examples takes about 3 weeks or so. IN most cases a vaccination stimulates the bodies immune response, so will be effective once the body has responded

The exception would be a passive vaccine - but those aren't used very commonly and the effects do not last for very long.

thanks x
Yes from what I have researched (and I had to research a lot due to DD having bad reactions to vacc) and we opted for singles, you can absolutely still get infected after a vaccine. I think something like 10% of children are not immune after MMR - some components of the MMR jab may take and not others, hence the introduction of the 2nd booster. Even this does not mean it will take if you have 20 shots.
The only way of knowing if any vaccine has taken is by doing the blood test to check for the immunity of a specific virus.

Hope this helps
