How to pronounce Rotavirus: [ro-ta-vi-rus]  or Listen

Two or more doses of a rotavirus vaccine are recommended for children by doctors as the best way to protect against rotavirus.

When should my baby get the drops?

Your baby should get either of the two available rotavirus vaccines:

  • RotaTeq® (RV5) is given in three doses at ages 2 months, 4 months, and 6 months
  • Rotarix® (RV1) is given in two doses at ages 2 months, and 4 months

There are two brands of rotavirus vaccine: RotaTeq® and Rotarix®. Both brands of the rotavirus vaccines are given by mouth (drops), not by a shot.

Why should my baby get the rotavirus drops?

  • Protects your baby from rotavirus, a potentially serious disease.
  • Protects your baby from developing diarrhea, vomiting, and stomach pain caused by rotavirus.
  • Keeps your child from missing school or childcare and you from missing work.

The rotavirus vaccine is safe.

The rotavirus vaccine is very safe and effective at preventing rotavirus. Vaccines, like any medicine, can have side effects. These are usually mild and go away on their own.

What are the side effects?

Side effects are rare, usually mild, and may include fussiness, diarrhea, and vomiting.

Some studies have shown a small rise in cases of intussusception within a week after the first or second dose of rotavirus vaccine. Intussusception is a type of bowel blockage that is treated in a hospital. Some babies might need surgery. Studies estimate a risk ranging from about 1 intussusception case in every 20,000 infants to 1 intussusception case in every 100,000 infants after vaccination.

Prepare for your child’s vaccine visit and learn about how you can:

  • Research vaccines and ready your child before the visit
  • Comfort your child during the appointment
  • Care for your child after the shot

Before, During, and After Shots

What is rotavirus?

Rotavirus causes severe diarrhea and vomiting. It affects mostly babies and young children. Diarrhea and vomiting can lead to serious dehydration (loss of body fluid). If dehydration is not treated, it can be deadly.

What are the symptoms of rotavirus?

Rotavirus symptoms include:

  • Fever
  • Watery diarrhea
  • Vomiting
  • Stomach pain

Diarrhea and vomiting can last for three to eight days. Children may stop eating and drinking while they are sick.

Is rotavirus serious?

Rotavirus can be very harmful. Diarrhea, vomiting, and fever can cause a loss of body fluids. This leads to dehydration, which can be very dangerous, especially for babies and young children. Some children need an IV (needle in their vein) in the hospital to replace lost fluids.

How does rotavirus spread?

Rotavirus commonly spreads in families, hospitals, and childcare centers.

People who are infected with rotavirus shed the virus in their poop. If you get rotavirus particles in your mouth, you can get sick. This can happen if you

  • Touch contaminated objects or surfaces and then put your fingers in your mouth
  • Put your unwashed hands that are contaminated with poop into your mouth
  • Eat contaminated food

Rotavirus can survive on objects for several days. It is very difficult to stop its spread just by hand washing or disinfecting surfaces. The best way to protect young children from rotavirus is to get them vaccinated.

Follow the vaccine schedule

The Centers for Disease Control and Prevention, American Academy of Family Physicians, and American Academy of Pediatrics strongly recommend children receive all vaccines according to the recommended vaccine schedule.

  • Learn the reasons you should follow the vaccine schedule.

Rotavirus vaccine side effects – NHS

Like all vaccines, the rotavirus vaccine can cause side effects, but they’re usually mild and do not last long.

Common side effects of the rotavirus vaccine

Babies who have the vaccine can sometimes become restless and irritable, and some may develop mild diarrhoea.

Rare side effects of the rotavirus vaccine

Allergic reaction

As with all vaccines, there’s a very small possibility (approximately 1 in 1 million) of the rotavirus vaccine causing a severe allergic reaction called anaphylaxis.

Anaphylaxis after a vaccination is very rare and is a medical emergency. If it does happen, it’s usually quick (within minutes). The people who give vaccinations are trained to deal with anaphylactic reactions. With treatment, children recover completely.

Blocked intestine

Very rarely, (between 1 and 6 in every 100,000 babies vaccinated), the rotavirus vaccine can affect a baby’s intestine (bowel), and they may develop a rare gut disorder called intussusception. This causes a blockage in the intestine.

The symptoms of intussusception are:

  • tummy ache
  • being sick
  • poo that looks like redcurrant jelly in the baby’s nappy

If this happens, contact your doctor immediately.

More about vaccine side effects in babies

Find out more in this leaflet about what to expect after vaccinations on GOV.UK.

What to do if your baby is unwell after the rotavirus vaccine

As with all vaccines, a few babies will have side effects, such as diarrhoea, although they’re usually mild and do not last long. Most babies will not have any problems at all.

Also, bear in mind that diarrhoea and vomiting in babies is common and may be unrelated to the vaccine.

A baby can get rotavirus infection after being vaccinated, but this is uncommon, and the illness is usually milder than it would have been if they had not been vaccinated.

See a GP if your baby is very unwell or the illness is lasting a long time, or if you’re concerned in any way about their health after the vaccination.

How to report a vaccine side effect

The Yellow Card Scheme allows you to report suspected side effects from a vaccine.

It’s run by the medicines safety watchdog the Medicines and Healthcare products Regulatory Agency (MHRA).

Immunizations against rotatec and rotavirus infection for children, Lakhta Junior in St.


Rotaviruses are the collective name of nine types of viruses, vaguely resembling a wheel (the Latin name is derived from “rota” – wheel).

Rotavirus infections are widespread and affect people of all ages. According to modern estimates, up to 95% of children by the age of five have time to get sick at least once. But it is for this age category, i.e. For infants and children under five years of age, rotavirus gastroenteritis (inflammation of the lining of the stomach and small intestine) is most dangerous due to its complications, in particular dehydration.

In third world countries where the level of medical care and care for a sick child leaves much to be desired, rotavirus infections are one of the factors of mortality, however, in the most developed countries, these diseases remain a serious threat. It would be unwise and irresponsible on the part of parents to neglect and ignore it – hoping that the child already has immunity to rotaviruses.

The fact is that immunity to one type of rotavirus does not protect against other types and strains. In addition, in this case, immune protection is cumulative: it is not enough to get sick once, although each subsequent infection will proceed the easier, the more such infections were transferred earlier. Accordingly, the first contacts with natural rotavirus cause the most pronounced, and sometimes severe symptoms, which are especially dangerous in early childhood.

This danger is eliminated by timely vaccination.
Thanks to the vaccination, the immune system will be ready to recognize and destroy rotavirus without much difficulty. Even if an infection occurs with a species that was not included in the composition of the vaccine, the infection will pass quickly and in a mild form, or it will not manifest itself with tangible symptoms at all, but the effect of immunity accumulation will still work. It is important to emphasize that modern vaccines are designed to protect against several of the most common types of rotavirus infection simultaneously.

Does your child need a rotavirus vaccine?

• Yes, if you want to protect your child from acute gastroenteritis and they have no contraindications for vaccination. At the same time, the presence of any infectious diseases that occur in a mild form is not a contraindication. The vaccine can be used for immunization, including premature babies born at least 25 weeks of gestation.

Rotavirus vaccines

In our Lakhta Junior clinic in St. Petersburg, you can vaccinate your child with the Rotatec vaccine produced by MERCK SHARP & DOHME Corp. (USA).

This oral vaccine (drops by mouth) contains the five most common strains of rotavirus in a live but significantly attenuated form. The introduction of such viral particles causes a sufficient immune response, but does not lead to the development of clinically significant symptoms.

Even without additional “training”, i.e. without any exposure to natural rotaviruses, immunity lasts for five years, which means sufficient protection for the entire period when infection is most dangerous.

Vaccination schedule

Attention! The vaccination scheme has strict age restrictions!

The vaccination course consists of three doses. The minimum (but not mandatory) interval between doses is one month.

• The first dose should be administered between 6 and 12 weeks of age
• The last dose should be given no later than 32 weeks of age

Therefore, if your child is over 24 weeks old, you will not be able to complete the full vaccination course within the manufacturer’s schedule. Children older than 32 weeks, as well as adolescents and adults, should not be given this vaccine.


The main contraindications to the administration of the Rotatec vaccine are:
• age discrepancy (see above)
• acute inflammatory processes accompanied by high fever (in these cases, vaccination is carried out after recovery or in remission)
• acute a form of diarrhea or vomiting (in these cases, vaccination is carried out in remission)
• immunodeficiency (congenital or acquired), as well as close contact of the vaccinated child with immunodeficient persons. Such contact should be limited at least one week before vaccination
• history of intussusception
• congenital malformations of the gastrointestinal tract predisposing to intussusception
• fructose intolerance, malabsorption of the glucose-galactose complex, sucrase and/or isomaltase deficiency an abnormal reaction to a previous administration of this vaccine

Always tell the doctor if:

• the child is receiving immunosuppressive therapy (for example, organ transplants, autoimmune diseases, etc.) or has cancer
• the child has recently (less than 42 days prior to vaccination) received a transfusion of blood or blood products, including immunoglobulins
• the child has active gastrointestinal disease, including chronic diarrhea
• the child has developmental delay (possible effects not studied )

Vaccine reaction

In most cases, the vaccine is well tolerated.
The most common possible reactions are fever above 38°C (about 20%), diarrhea (about 18%) and vomiting (about 10%).
