How long is polio vaccine good for?
The last dose in either series should be given after 4 years of age and at least 6 months after the previous dose..
Is it OK to have polio vaccine twice?
Yes. Getting an extra dose of vaccine when an immunization history is unknown is not harmful. It is better to ensure protection by getting the vaccine than risk leaving your child unprotected. You may be able to locate your child’s record if you have lost it.
Why polio vaccine is given again and again?
The oral polio vaccine is effective as it not only protects the children from contracting the virus, but also prevents them from carrying the virus in their intestines. Several doses need to be given spaced apart to build sufficient immunity, especially in areas where poor nutrition can weaken immune systems.
Do people still get polio?
Polio does still exist, although polio cases have decreased by over 99% since 1988, from an estimated more than 350 000 cases to 22 reported cases in 2017. This reduction is the result of the global effort to eradicate the disease.
What is the mortality rate of polio?
Overall, 5 to 10 percent of patients with paralytic polio die due to the paralysis of muscles used for breathing. The case fatality rate (CFR) varies by age: 2 to 5 percent of children and up to 15 to 30 percent of adults die.
What is the age limit for polio drops?
Therefore, the upper age for OPV is still 5 years, either for the first dose or for the ‘umpteenth’ dose. These days, I cannot say what is the last dose since some 4-year-old children may receive up to 17-19 doses in the States in which 4 doses are being given in campaigns.
Can adults catch polio?
Adults at risk include those who are traveling to parts of the world where polio still occurs or those who care for people who have polio.
How long do polio survivors live?
For years, most polio survivors lived active lives, their memory of polio mainly forgotten, their health status stable. But by the late 1970s, survivors who were 20 or more years past their original diagnosis began noting new problems, including fatigue, pain, breathing or swallowing problems, and additional weakness.
Does polio vaccine last a lifetime?
Higher-risk adults who have had one or two doses of polio vaccine in the past should get the remaining one or two doses. It doesn’t matter how long it has been since the earlier dose(s). Higher-risk adults who have had three or more doses of polio vaccine in the past may get a lifetime booster dose of IPV.
What if polio vaccine is missed?
A. Polio vaccines are of two kinds, oral and injectable. If injectable has been given but you have missed the oral, you can go to a hospital and give that one as well. Both are important and have to be given.
Where did polio originally come from?
1894, first outbreak of polio in epidemic form in the U.S. occurs in Vermont, with 132 cases. 1908, Karl Landsteiner and Erwin Popper identify a virus as the cause of polio by transmitting the disease to a monkey.
What happens if you get polio?
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person. Polio is more common in infants and young children and occurs under conditions of poor hygiene.
Is polio a lifelong disease?
Paralysis caused by poliovirus occurs when the virus replicates in and attacks the nervous system. The paralysis can be lifelong, and it can be deadly. It most often sickens children younger than 5 years old.
How many times can we give polio drops?
Each child requires just two drops per dose to be immunized against polio. Usually administered four times if the EPI schedule is followed, OPV is safe and effective in providing protection against the paralyzing poliovirus.
When did they stop vaccinating for polio?
OPV was recommended for use in the United States for almost 40 years, from 1963 until 2000. The results have been miraculous: Polio was eliminated from the United States in 1979 and from the Western Hemisphere in 1991. Since 2000, only IPV is recommended to prevent polio in the United States.
