Advantages of Private Vaccination over Government centers for Yellow Fever vaccination in India?

Here are the advantages of a private center over government approved centers...
1. WHO Pre-approved vaccination (Stamaril - French vaccine - Aventis Pharma) used.
2. Convenient ( given all days, morning and evening, and even on most holidays, except Sundays)

3. Less chances of Side-effects, since high quality French vaccine used, unlike government centers using multi-dose vaccinations of potentially weaker quality (Russian/ Chinese non WHO pre-approved vaccines).

4. Single dose vaccine given, unlike government set up where one vaccine is used to vaccinate 10 individuals (multi-dose vial), leading to increased risk of infections & side-effects.

5. Proper signed and stamped WHO International certificate of vaccination provided, that is valid Internationally for 10 years.
