Rotavirus vaccine


Vaccination is the best protection against rotavirus gastroenteritis and its complications. It is estimated that over 95% of children will have suffered a rotavirus gastroenteritis before the age of 5.

The vaccine is given in 2 doses. The first dose should be given before the age of 20 weeks, and the second one before the age of 8 months.

Because the virus contained in the vaccine may be found in stools for about 10 days after vaccination, it is important to wash your hands carefully when changing diapers.


Some symptoms may be caused by the vaccine. Other problems may occur by chance and are not related to the vaccine, e.g. cold, gastro, headache.

Rotavirus vaccine is safe. In most cases, it does not cause any reaction.
