There is a blood test you can take to see if you need it, but I’ve been told that the test will come up negative (meaning you need to re-vaccinate) for 90% of adults between the ages of 30 and 60. I’ve also been told by a doctor that a negative result doesn’t necessarily mean that the person isn’t immune, just that their measles antibodies is less than a certain percentage.
Derech agav, there’s a video going around of the crowd outside Bill DeBlasio’s announcement for a fine for un-immunized children. One repeats “Show me a double-blind study” several times which is the exact same thing one of the users in the thread below kept saying. I wonder if it’s the same person or this is a standard anti-vaxx soundbite.
