Get all vaccines on time.
Immunization has saved more lives in Canada in the last 50 years than any other health measure.
What is the rotavirus vaccine?
The rotavirus vaccine helps protect babies against diarrhea and vomiting caused by rotavirus. It does not protect against diarrhea and vomiting caused by other viruses. The vaccine contains a weakened form of rotavirus that does not cause disease. The vaccine is approved by Health Canada.
The rotavirus vaccine is provided free as part of your child’s routine immunizations. Call your health care provider to make an appointment.
Who should get the rotavirus vaccine?
The rotavirus vaccine is given to babies starting at 2 months of age. It is given as a series of 2 doses. The first dose is given at 2 months of age, and the second at 4 months. The rotavirus vaccine is given at the same time as other childhood immunizations.
|Rotavirus Vaccine||Child’s Age at Immunization|
|1st dose||2 months|
|2nd dose||4 months|
It is important that your baby gets the rotavirus vaccine on time. The first dose of the vaccine must be given before 20 weeks of age and the second dose by 8 months of age. Two doses of the vaccine are needed for best protection.
It is important to keep a record of all immunizations received.
The rotavirus vaccine is given by mouth. A few drops of the liquid vaccine are placed into your baby’s mouth to swallow.
The virus from the vaccine may be found in your baby’s stool for at least 10 days after immunization. Parents and caregivers should wash their hands thoroughly after changing diapers.
What are the benefits of the rotavirus vaccine?
The vaccine prevents more than 3 out of 4 cases of rotavirus disease, and almost all severe cases, including hospitalizations. When you get your child immunized you help protect others as well.
What are the possible reactions after the vaccine?
Vaccines are very safe. It is much safer to get the vaccine than to get a rotavirus infection.
Most babies do not have any reactions after they get the rotavirus vaccine. Some may have diarrhea, crankiness, stomach pain, gas or an itchy rash after immunization.
In some countries outside of Canada, a very rare risk of intussusception (a blockage of the intestine) has been seen in the week after the first dose of rotavirus vaccine. The risk of intussuception is about 1 to 2 cases for every 100,000 babies that get the vaccine. At most, this could affect 1 baby a year in B.C. By comparison, each year in B.C. about 1 in 4,000 children under the age of 1 get intussusception without having received the vaccine.
Signs of intussusception may include a swollen abdomen, frequent vomiting, and bloody stools. Your baby could seem weak and irritable and have several bouts of intense crying. If your baby shows these signs, you should take your baby to the nearest emergency department.
It is important to stay in the clinic for 15 minutes after getting any vaccine because there is an extremely rare possibility, less than 1 in a million, of a life-threatening allergic reaction called anaphylaxis. This may include hives, difficulty breathing, or swelling of the throat, tongue or lips. Should this reaction occur your health care provider is prepared to treat it. Emergency treatment includes the administration of epinephrine (adrenaline) and transfer by ambulance to the the nearest emergency department. If symptoms develop after you leave the clinic, call 9-1-1 or the local emergency number.

Who should not get the rotavirus vaccine?
Talk to your health care provider if your baby:
- Has had a life-threatening reaction to a previous dose of rotavirus vaccine or any component of the vaccine
- Has an immune system weakened by disease or medical treatment
- There is a family history of weakened immune systems
- Had intussusception or has an intestinal disorder that may result in intussusception
Babies who have moderate or severe diarrhea or vomiting, or a serious illness should not be immunized until they have recovered from their illness.
There is no need to delay getting immunized because of a cold or other mild illness. However, if you have concerns, speak with your health care provider.
What is rotavirus?
Rotavirus is a virus that causes gastroenteritis, sometimes called the stomach flu. Rotavirus is the most common cause of diarrhea and hospitalization for diarrhea in children under 5 years of age. Almost all children will have at least 1 rotavirus infection before they are 5 years of age.
The first symptoms of rotavirus infection are often fever and vomiting, followed by diarrhea and stomach pain. These symptoms appear 1 to 3 days after a person has been infected with the virus. Diarrhea can last from 4 to 8 days. Young children can become dehydrated if the diarrhea or vomiting is severe and happens often. If this is not treated, the child may die.
Rotavirus is easily spread through touching the stools of an infected child. This can happen when handling diapers. Washing your hands often with soap and water is the best way to prevent the spread of rotavirus. A child who is sick with diarrhea or vomiting should not go to day care or have contact with other children until 48 hours after the diarrhea or vomiting has stopped. For tips on hand washing, see HealthLinkBC File #85 Hand Washing: Help Stop the Spread of Germs.
