1, rotavirus vaccine is to prevent rotavirus infection. The common symptoms of rotavirus infection are fever, diarrhea and vomiting, and the most serious problem is dehydration, electrolyte disorder and even death. Domestic rotavirus vaccine is monovalent vaccine, while imported rotavirus vaccine is pentavalent vaccine.

2. There are great differences between them in terms of procedures.

The initial vaccination time of imported rotavirus vaccine is 6 weeks, and then every dose is 4- 10 weeks, and three doses are enough, but the last dose is not later than 32 weeks.

Vaccination time of domestic rotating seedlings: take 1 dose from 2 months old, and then take 1 dose every year until 4 years old. The dosage is 3ml each time.

3. Rotavirus vaccine has strict time requirements. If you don't eat it for more than 12 weeks, you will miss the vaccination time and can't vaccinate the vaccine again. Therefore, parents who are willing to vaccinate the vaccine should be careful not to miss the vaccination time.

After rotavirus vaccination, there may be some slight adverse reactions, such as fever, mild vomiting and diarrhea, but these 1~2 days will relieve themselves without excessive worry. But if you have anaphylactic shock or rash, you need to see a doctor in time.
