What is the maximum age for the first dose of the Rotavirus vaccine?

The maximum age for the first dose of the Rotavirus vaccine is 14 weeks and 6 days. This is consistent with recommendations from health organizations such as the Centers for Disease Control and Prevention (CDC). The Rotavirus vaccine is typically administered in a series, and the timing is important to ensure that infants receive the vaccine while they are still at an optimal age to benefit from it.

Administering the first dose beyond this age could lead to reduced efficacy or failure to provide adequate protection against Rotavirus, which can cause severe diarrhea in infants. Therefore, adhering to this age limit is crucial for effective immunization. The other options provided suggest ages that either exceed the guidelines or are not within the acceptable range for starting this vaccination series.
