Is it possible to prevent cytomegalovirus infection? Is there a CMV vaccine?
Because CMV is a common virus, it is not always possible to prevent infection. Pregnant women should avoid exposure to CMV to prevent congenital CMV infection. Steps to reduce the risk of CMV infection include the following:
Washing hands frequently for 15-20 seconds, especially when in contact with young children, changing diapers, and handling toys, or when exposed to oral secretions
Avoiding sharing food, drinks, and eating utensils with others
Avoiding contact with saliva when kissing a child
Cleaning toys, countertops, and surfaces that come into contact with a child's urine or saliva
Using condoms during sexual contact
There is no available vaccine for preventing congenital CMV infection or CMV disease in individuals with suppressed immune systems. However, researchers are studying experimental vaccines in humans. It may be a number of years before there is a Food and Drug Administration (FDA)-approved CMV vaccine.
