Disadvantages. 1  IPV induces very low levels of immunity in the intestine. As a result, when a person immunized with IPV is infected with wild poliovirus, the virus can still multiply inside the intestines and be shed in the faeces, risking continued circulation. 2  IPV is over five times more expensive than OPV.
Hello, Thanks for your question. vibration in the absence of any pain in right lower abdomen is likely related to the muscle twitchings. The abdominal muscles can twitch giving vibration sensations. This can happen due to: 1. Dehydration---common cause. Plenty of fluids (sports drinks like Gatorade) should resolve the issue. 2. Nerve impingement---nerve impingement at the lower spine can cause vibration sensation. 3. Systemic conditions: diabetes, vitamin deficiencies can affect the local nerves causing this sensation. Improve your diet & take a multivitamin supplement daily.
When vibrations are attenuated in thebody, its energy is absorbed by the tissue and organs. The muscles are important in this respect. Vibrationleads to both voluntary and involuntary contractions of muscles, and can cause local muscle fatigue,particularly when the vibration is at the resonant-frequency level.
