Rotarix Update

Tuesday, March 30, 2010

The manufacturers of Rotarix rotavirus vaccine have recommended the temporary discontinuation of administration of the vaccine because new technology has found the presence of extraneous porcine (pig) viral DNA in the vaccine preparation. This virus is felt to be safe and to not cause any known problems for humans or pigs (it is present in everyday meat products) and does not interfere with the safety or the efficacy of the vaccine. However, the presence does raise concerns about the manufacture of the vaccine that resulted in the temporary suspension of the product.

Rotavirus is a common gastrointestinal virus that causes diarrhea, vomiting and fever in young infants, especially infants who are in day care or have older siblings at home. In the US, fortunately, rotavirus is not a deadly disease but does cause the hospitalization of thousands of children each year.

There is another rotavirus vaccine called Rotateq that can be substituted for Rotarix. A decision to continue rotavirus vaccine depends on several factors including those situations listed above. You should discuss with your provider how to proceed (or if to proceed) with the vaccine. Rotateq requires three doses of the vaccine versus two by Rotarix and the series must be completed by 8 months of age.

Finally, there is NO evidence that the vaccine given has caused any harm to children and no tests are required in the way of follow up because your child received this vaccine.
