It would be awesome if Grindr would add a place for Hepatitis A & B vaccinations as well as HPV vaccinations. As both of these are STIs, it would t be far out from necessary for Grindr to add these to the list.
Also, adding a DoxyPEP place would be awesome too. As it is becoming more mainstream to use it to prevent bacterial STIs, it would be appropriate to have a spit in the Grindr profile to show we use it. Plus the awareness would help more people get on it.

It’s all about improving these things and using grindr to do so.
