Rotavirus Vaccine Dosage
Depending on the specific type of vaccine, dosing schedules for the rotavirus vaccine can vary. The standard dosage for Rotarix is two doses given by mouth at least four weeks apart. For RotaTeq, the standard dosage is three doses given 4 to 10 weeks apart. These dosing schedules usually coincide nicely with standard well-baby visits.
Rotavirus Vaccine Dosage: An Introduction
The recommended dosing schedule for the rotavirus vaccine (Rotarix®, RotaTeq®) will vary, depending on which vaccine is used.
In March 2010, the United States Food and Drug Administration (FDA) recommended that Rotarix not be used, at least temporarily, since DNA from porcine circovirus type 1 (PCV1) has been found in the vaccine. This means that DNA from a virus found in pigs has been found in the vaccine. However, in May 2010, the FDA announced that it is safe to begin using Rotarix again, since PCV1 poses no known health risks to humans.
No similar problems have been found with RotaTeq.
For Rotarix, the standard dosage is two doses (each of 1 mL given by mouth) given at least four weeks apart. The first dosage is recommended to be given at 6 weeks of age but could be given as late as 20 weeks. The second dose should be given no later than 24 weeks of age (since rotavirus vaccine was not studied in older infants). The vaccine schedule is flexible enough to fit nicely with standard well-baby visits.
For RotaTeq, the standard schedule is three dosages (each of 2 mL given by mouth) given 4 to 10 weeks apart. The dosing schedule usually coincides nicely with standard well-baby visits. The first dosage is given sometime between 6 and 12 weeks of age, and the third one needs to be completed before 32 weeks of age (since RotaTeq was not studied in older infants).
