I do what I can to reduce our risks, I use seat belts, I lock my doors, I vaccinate, I make a healthy diet and exercise routine for my family, we use proper handwashing techniques, my kids are in car seats as appropriate and so on. And then we go about our daily lives. We do what we reasonably can to keep ourselves safe without hiding in a bunker underground, and go about our day. I'm not sure why that is so hard to understand.
let's use seatbelts as an analogy.
Let's say seatbelts had a failure rate of 30%. Let's say you can test whether or not the seatbelt worked before an accident. Why wouldn't you get it tested? If your seatbelt was not working properly, you could get a new one.
Vaccines are the same way. If you know a vaccine has a failure rate that is too high, then it makes sense to get tested and see whether or not you have the appropriate levels of antibodies.
There are things you can do if your titres are low - revaccinate, primarily. I would think you would want to - isn't one of the goals of vaccination protection?
There are people on this forum who have been vaccinated more than the norm because a vaccine did not take. Occasionally people never show antibodies despite revaccination - and even that can be good info to have.
I don't think people have to titre test for everything (although if it is only one blood draw - why not?) just diseases that are prevalent and known to have a high failure rate. I also do not think it is necessary to put a child through an extra needle unless an outbreak is afoot - but most kids do have blood draws from time to time, so while a blood draw is being done for another disease, it might be a good time to check titres.
Lastly, and this seems to have been missed a lot in this thread: vaccines have risks. MMR in particular is a fairly reactive vaccine, and one dose of MMR takes in over 95% of the population. I absolutely think people should get a titre drawn before putting their child at risk with a second MMR shot when it is unnecessary for the vast majority of the population.
From the measles VIS:
• Fever (up to 1 person out of 6)
• Mild rash (about 1 person out of 20)
• Swelling of glands in the cheeks or neck (about 1 person out of 75)
If these problems occur, it is usually within 6-14 days after the shot. They occur less often after the second dose.
• Seizure (jerking or staring) caused by fever (about 1 out of 3,000 doses)
• Temporary pain and stiffness in the joints, mostly in teenage or adult women (up to 1 out of 4)
• Temporary low platelet count, which can cause a bleeding disorder (about 1 out of 30,000 doses)
The CDC Pink book notes that 5-15% of people given MMR get a fever over 103 degrees.
