The Live Attenuated Human Rotavirus Vaccine, sold commercially under the name RRV-TV, Rotarix or RotaTeq serves to protect children from gastroenteritis that causes diarrhea and vomiting, caused by Rotavirus infection.
This vaccine serves to prevent Rotavirus infections, since when the child receives the vaccine, his / her immune system is stimulated to produce antibodies against the most common types of Rotavirus. These antibodies will protect the body against future infections, however they are not 100% effective, although they are very useful in reducing the intensity of symptoms, which ends up being of great help because Rotavirus causes severe diarrhea and vomiting.
What is it for
The rotavirus vaccine is administered in order to prevent infection by rotavirus, which is a virus belonging to the Reoviridae family and which causes severe diarrhea mainly in children between 6 months and 2 years.
Prevention of rotavirus infection should be done as directed by the pediatrician, as otherwise the baby's life may be at risk, as in some cases diarrhea is so severe that it can result in severe dehydration within hours. Rotavirus symptoms can last between 8 and 10 days and there may be severe diarrhea, with a strong and acidic odor, which can make the baby's intimate area red and sensitive, in addition to pain in the belly, vomiting and high fever, usually between 39 and 40ºC. Learn to recognize the symptoms of rotavirus infection.
How to take
The rotavirus vaccine is administered orally, in the form of a drop, and can be classified as monovalent, when it contains only one type of attenuated rotavirus, or pentavalent, when it consists of the five types of rotavirus with low activity.
