Well, I don't know anything about Eastern Europe, but if is only for your personal knowledge and doesn't actually save you from getting shots, I wouldn't do it. It is expensive!
However, having titers checked can get you out of some shots here in the US in some areas (in Maryland, anyway). I'm surprised more people don't do this if it is available to them.
Who cares if titer tests are valid, if the government accepts them as proof of immunity? I intend to ask my ped for titer tests for polio, MMR, hepatitis B, and varicella and when I am refused, I'm going to go to Dr. Tenpenny's website:
http://drtenpenny.com/titer.aspx
and order the titers myself. It says right on the MD vax schedule that positive immunity titers are accepted in lieu of vaccines for polio, MMR, varicella, and hep B. Hopefully, by doing this I can save my DD six shots. I figure she will get one dose of each vaccine, and titers from then on.
I would like to know if this approach has worked for anyone?
They usually check dogs' immunity titers before giving them annual vaccinations, I can't believe we don't afford our children the same!
