As much as possible, you should try to ensure you can receive your first and second doses from the same provider. You should follow local vaccination policies wherever you are. If you get your first dose and then travel, be sure to bring your vaccination record with you. This will help your vaccine clinic know which product you will need for the second dose and when. When you set up your second dose appointment, be sure to ask if the vaccination clinic will be able to give you the same product that you got for your first dose.
