[Suggestion] Add an option for choosing vaccine other than Covishield, Covaxin

[nivramam]

So my parents are vaccinated with 2 doses of Pfizer which was in USA. Now after 6months visit they are back and the app is asking them to choose amongst: Covishield, Covaxin or Do not know. Instead, it can offer a "Other vaccine" option and subsequently ask the user to type the vaccine name or provide the list of most common vaccines outside of India.
