What Is Vaccination Certificate
The author gives more than a simple answer as to who can obtain a vaccination certificate. No. Two issues are faced by passport applicants. Privacy is the first.

I received a certificate so I could write on my blog and travel with no restrictions. You can now travel to new places and feel new emotions all by yourself, and not through photos from others. Read the article that I recommend.
