Dear Dr. My baby boy recently had his 6-week vaccinations, but the Rotavirus 1 vaccine was missed. Could you please let me know if there are any risks with this delay, and when it would be best to administer the pending Rotavirus vaccine? Also, could you advise on whether the oral or injectable form of the vaccine is recommended? I am attaching his vaccination certificate for your reference. Thank you very much for your assistance.
