Question

After administering the rotavirus vaccine to our child, we discovered that the vaccine had expired. What should we do? What are the side effects?

Answer

The rotavirus vaccine is used to prevent rotavirus infection, which can cause the autumn vomiting syndrome. If the vaccine has expired, it may no longer be effective in preventing the infection. As for the side effects, since the vaccine administered has expired, the long-term side effects are not yet clear. It is recommended to closely monitor your child’s health condition and consult with a doctor for professional advice.
