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).
All four doses of the inactivated polio vaccine (IPV) are given by injection. Sometimes they're given at the same time as the DTaP, hepatitis B, or Hib vaccines. Another type of vaccine â oral polio vaccine (OPV), which is made from a live, weakened version of the virus â has not been used in the United States since 2000. The OPV was considered somewhat more effective than the IPV.
