Pentavalent rotavirus vaccine is less effective if half of the vaccine is vomited up just after consumption, and partially effective if it is retained in the body for a period of time and then vomited up. Pentavalent rotavirus usually requires three doses, which can be replenished later.
Pentavalent rotavirus vaccine can be taken orally, usually through the mucous membranes of the mouth, throat, and esophagus to play a role. If the vaccine is spit out quickly after it enters the stomach, it will remain in the mucous membranes for a shorter period of time, and if the amount absorbed is small, then the effect will be small, and it will not be very useful, so you can consult with your doctor to see if you want to supplement the vaccine.
If it is consumed and kept in the body for a period of time and then spit out, the preparation will be retained in the body for a longer period of time and the effect will be more obvious.
However, the pentavalent rotavirus vaccine usually needs to be taken three times, so if the effect of one dose is reduced, it can be supplemented by the remaining two doses, which will also enable the baby to produce sufficient antibodies.
