What is the difference between measles mumps and rubella
Some people may need 2 doses. Vaccines are usually very safe. But they carry a small risk of side effects, such as an allergic reaction. Getting an MMR vaccine is much safer than contracting any of the 3 diseases. Common reactions to these vaccines may include the following:. Give your child over-the-counter pain and fever-lowering medicine, as instructed by your child's healthcare provider. Don't give your child aspirin. If your child has symptoms of a severe reaction, which are usually rare, call or get emergency medical help.
These symptoms include:. Search Encyclopedia. When are MMR vaccines given? But the process of "cell culture adaptation" changes all of that. Natural measles virus was first taken from someone infected with measles.
The virus was then "grown" in cells taken from chick embryos. By growing the virus in chick embryo cells, it became less and less able to grow in human cells. This happened because the genes that tell measles virus how to reproduce itself were changed. Now the virus reproduced itself very poorly. When this vaccine virus a now modified form of the natural virus is put back into the body, it grows very poorly. Whereas natural measles virus reproduces itself thousands of times during natural infection, the measles vaccine virus reproduces itself probably fewer than 20 times.
That is why natural measles virus causes illness, but measles vaccine virus doesn't. However, because the measles vaccine virus reproduces itself a little bit, it induces immunity against measles that is life-long. See how vaccines work. The effectiveness of the measles vaccine has been dramatic.
Before the first measles vaccine became available in the United States in , million people were diagnosed with measles, about 48, were admitted to hospitals and about people died every year. In , 55 cases of measles were reported to the CDC. However, decreases in the use of the MMR vaccine have led to increasingly larger outbreaks. For example, during , outbreaks led to about cases of measles.
And in , more than cases were reported. In , the U. These outbreaks occurred because a critical number of parents had chosen not to vaccinate their children. The measles vaccine causes some children to develop soreness in the local area of the shot, and occasionally a low-grade fever, after receipt of MMR. Reports have also indicated rare cases of fevers greater than degrees Fahrenheit, usually five to 12 days after receiving the shot. In some children about 1 of every 3,, children , the fever may increase rapidly causing a fever-associated seizure.
Known as febrile seizures, these seizures, while scary, do not cause long-term harm. Also, some children develop a mild, measles-like rash about seven to 12 days after getting the MMR vaccine.
Children with this reaction can still get the MMR vaccine in the future. Children with measles rash from the vaccine are not contagious to other people. Because the measles vaccine is made in chick embryos, it was once thought that children with egg allergies should not receive the MMR vaccine.
This is no longer the case. Studies showed that even children with severe egg allergies could receive the MMR vaccine without consequence. Rarely, the combination measles-mumps-rubella MMR vaccine can also cause a short-lived decrease in the number of platelets that circulate in the body. Platelets are cells that help the blood to clot, such as, for example, after the skin is cut.
This reaction occurs in roughly 1 of every 24, people who receive the vaccine and has never been fatal. The mumps vaccine virus is "weakened" by a process called "cell culture adaptation.
Natural mumps virus normally grows in cells of the salivary glands. Natural mumps virus reproduces itself thousands of times, occasionally causes severe disease, and is passed on to the next person unchanged. Natural mumps virus was first taken from a little girl named Jeryl Lynn Hilleman. Jeryl Lynn was the 5-year-old daughter of Dr. Hilleman then "grew" the virus in eggs. By growing the virus in hen's eggs it became less and less able to grow in human cells.
This happened because the genes that tell mumps virus how to reproduce itself were changed. Now the mumps virus reproduced itself very poorly. When this vaccine virus now a modified form of the natural virus was put back into other children, it grew very poorly. Whereas natural mumps virus reproduces itself thousands of times during infection, the mumps vaccine virus reproduces itself probably fewer than 20 times.
That is why natural mumps virus causes illness, but mumps vaccine virus doesn't. However, because the mumps vaccine virus reproduces itself a little bit, it induces immunity against mumps that is life-long. After receiving the mump vaccine, children may develop soreness in the local area of the shot, and occasionally a low-grade fever. Because the mumps vaccine is made in chick embryo cells, it was once thought that children with egg allergies should not receive the MMR vaccine.
Studies showed that even those with severe egg allergies could receive MMR vaccine without serious consequence.
Like the measles and mumps vaccines, the rubella vaccine is a live, "weakened" form of natural rubella virus. The rubella vaccine virus is "weakened" by a process called "cell culture adaptation. Natural rubella virus normally grows in cells that line the back of the throat. Natural rubella virus reproduces itself thousands of times, occasionally causes severe disease, and is passed on to the next person unchanged. Natural rubella virus was first taken from someone infected with rubella.
The virus was then "grown" in human embryo fibroblast cells. Smeeth L, et al. Chen W, et al. DeStefano F et al. Lingam R, et al. Makela A, et al. Madsen KM, et al. Black C, et al. Taylor B, et al.

Ann Neurol. Are diseases like measles and mumps making a comeback? As more and more outbreaks are reported nationwide, public health officials in Utah are urging citizens to take preventative action against serious diseases like measles and mumps. Mumps have a 16 to day incubation period before symptoms appear — sometimes even longer. The long incubation period is often how the virus spreads quickly through a community.
The first signs of mumps include:. Most people with mumps recover completely in a few weeks, but in some cases, mumps can result in serious complications including deafness, meningitis, or encephalitis.
The symptoms of measles generally occur 7 to 14 days after a person becomes infected.
