Why is the Smallpox Vaccine Not Given to Children as a Safety Measure?
In the United States, children are commonly vaccinated against diseases like mumps, measles, and rubella. However, the smallpox vaccine is not included in routine childhood vaccinations. This is due to the fact that the smallpox vaccine contains a live virus that is similar to, but not the actual smallpox virus. Studies have shown that this vaccine can potentially cause severe side effects, such as heart or brain infections, in some cases. As a result, experts advise against administering the smallpox vaccine unnecessarily, especially to infants. Unless there is an ongoing outbreak, the risks associated with this vaccine outweigh the potential health benefits.
How Long Does the Smallpox Vaccine Provide Protection?
Experts have conducted numerous studies to determine the effectiveness and duration of protection provided by the smallpox vaccine, especially if administered during childhood. Laboratory reports suggest that individuals who receive the vaccine can expect to maintain partial or full immunity against the smallpox virus for approximately ten years. However, revaccination has the potential to extend this immunity period to up to twenty years.
It is important to note that while the smallpox vaccine is not currently administered to children, in the event of an outbreak, even those who were previously vaccinated as children would be given a new vaccine as a precautionary measure.
