Can an 11-month-old child who received his first dose of polio vaccine at 9 months be given his IPV-2 today?

The answer to the question of whether an 11-month-old child, who received the first dose of the polio vaccine at 9 months, can be given the second dose (IPV-2) today is affirmative.

In the vaccination schedule for polio, the inactivated poliovirus vaccine (IPV) is typically given in a series, with the first dose recommended between 2 to 6 months of age, and the subsequent doses following at appropriate intervals. The Centers for Disease Control and Prevention (CDC) recommends that the second dose of IPV can be administered as early as 4 weeks after the first dose. Given that the child is 11 months old and has received the first dose 2 months prior, it is appropriate and safe to administer the second dose of IPV today, aligning with the recommended immunization guidelines.

This approach ensures that the child is adequately protected against poliovirus, maintaining the recommended immunization schedule to reduce the risk of infection. Timely administration of vaccines is crucial in achieving optimal immune response and public health goals.
