The key goal of this thesis application is to give average computer users a simple way to keep track of all the vaccines they've received. Once the users are registered to the website, users can request appointments, withdraw appointment requests, keep track of when they have appointments and the vaccinations they have got. And they can modify their profile via the account dashboard. Admins will accept and delete appointments, add new vaccines to the list of vaccines, and adjust the status of vaccines that are currently on the list. The vaccines can be either active or inactive. Inactive vaccines will not show up for end-users when they are trying to request an appointment.
