Polio Antibody Testing to Determine Immunity
Dr Bruno’s Original Post:
Testing for Types 1 and 3 Antibodies The case of paralytic polio in lower New York State, caused by the mutated Type 2 vaccine, has prompted survivors to ask whether they had been fully vaccinated and have antibodies to all three types of poliovirus. Commercial laboratories will test for the presence of poliovirus antibodies but only for Type 1 and Type 3, since wild Type 2 poliovirus is no longer circulating. Unfortunately, it is the mutated Type 2 oral vaccine strain that currently is circulating and being found in wastewater.
The CDC states, "Demonstrating antibodies to poliovirus types 1 and 3 does not reliably indicate protection against poliovirus type 2. In the absence of the availability of testing for antibodies to all 3 serotypes, serologic testing is no longer recommended to assess immunity." Source: CDC
What's more, infectious disease specialist Dr. Paul Offit stated that laboratories can "find" poliovirus antibodies that are in fact antibodies against “cousin” non-polio enteroviruses, making antibody testing worthless.
