Our 9-year-old got Covid 5 days after her first shot of Pfizer. In  Western countries she could get her next shot 4-6 weeks after recovering but I'm told it is 3 months in Thailand.

 

Does anyone know the rule here? I can't find the info in English.

yes, thailand is minimum 90 days.

if she even needs one.

no need to rush. There might be new generation vax coming. Moderna planned 2nd generation this year.

Also mix and match can work better
