I don't know a single person who isn't vaccinated who uses inconvenience as a reason for their decision.COVID vaccines still have a long way to go. In order for vaccines to remain most effective, we can't let it become a flu-like situation where there are so many variants that we literally have to guess which ones will be most prevalent in a given year. That said, there will likely be at least a 2nd iteration of the mRNA vaccines. Though they could be a year or two off, they will presumably be more effective.
I would stop being vaccinated when it is inconvenient to get vaccinated. People act like they are so inconvenienced by having to go get a free shot on their own time and terms. Sounds like a bunch of bitching to me. COVID vaccines will likely become an annual routine just like the flu shot. mRNA technology will allow for all mRNA shots to be combined into a single shot. I will visit my doctor for my physical like I do every year, and they will give me a single injection. It doesn't hurt, my life isn't altered in any way shape or form - not then or in the future - and I am protected on some level.
Your experience of "it doesn't hurt" and "my life isn't altered in any way shape or form" doesn't carry forward to everyone who has received the vaccination as I'm sure you know. I'd be careful not to speak in absolute terms. So far you've had no drawbacks from vaccines, good on you.
