How many doses of Rotarix are given to infants?

  1. 2 doses

  2. 3 doses

  3. 4 doses

  4. 5 doses

The correct answer is: 2 doses

The recommended dose schedule for Rotarix, a vaccine for rotavirus, is 2 doses given orally, with the first dose at 2 months of age and the second dose at 4 months of age. The other options, 3 doses, 4 doses, and 5 doses, are incorrect because they do not align with the recommended schedule. Giving more doses of the vaccine than recommended may not provide any extra protection and could potentially cause harm to the infant. Therefore, the correct answer is A 2 doses.
