Factors that affect the fluid, which might contribute to Meniere's disease, include: 1  Improper fluid drainage, perhaps because of a blockage or anatomic abnormality. 2  Abnormal immune response. 3  Allergies. Viral infection.  Genetic 1  predisposition. Head trauma.  Migraines.
Oral poliovirus vaccine (OPV) contains live attenuated poliovirus (Sabin strain types 1, 2 and 3) and is intended for polio prophylaxis in infants 6-12 weeks of age, all unimmunized children up to 18 years of age, and high-risk adults. Adults, however, should receive the inactivated poliovirus vaccine (IPV).
There are two types of polio vaccine: trivalent oral polio vaccine (tOPV), given by mouth, and inactivated polio vaccine (IPV), given as an injection. As of January 2000, tOPV is no longer recommended for immunization in the United States.
