EDIT: Though the behavior towards you just seems spiteful now.
The reason why I'm backing h3cate and the reason why he probably spoke up is that the notion that this is a civic duty invites the idea that it's sure to protect other people, when it hasn't yet been proven to do so.
Indeed, one should get it on the chance that it does, but I'm betting a lot of people will assume the vaccine suffices for others' protection.
However, those who get the vaccine, by lowering their own chance to get sick, will contribute to the well-being of everybody: once most people are vaccinated the number of cases needing hospital has to eventually drop.
If the amount of virus produced in the body of vaccinated drops just for some percentage, the chance of transmission in some occasions will somewhat drop, even if it won't be zero. That will help everybody.
Still, there is reasonable probability that there will be a period of time when it will be hard to explain to many that they should keep behaving like potential virus carriers even after they received the vaccine (masks, distancing etc). If they do that then they will contribute to the earlier end of pandemic and directly and indirectly protect some vulnerable. By still behaving like potential carriers they will reduce already mentioned chance of transmission and contribute to health of everybody else. It's somehow non-intuitive. Also non-intuitive: some percentage of all vaccinated will with such behavior directly protect themselves too, simply because even 95% isn't 100% -- that 95% means one of 20 still gets sick, on average.
Then it won't be the first time during this pandemics that "dumbing down" the message isn't the best way to communicate.
Whoever cares about those who are most in danger, and even whoever just cares about the economy, should once again try to understand the nuances and then explain them to those who don't.

> Challenge studies in vaccinated primates showed reductions in pathology, symptoms, and viral load in the lower respiratory tract, but failed to elicit sterilising immunity in the upper airways. Sterilising immunity in the upper airways has been claimed for one vaccine, but peer-reviewed publication of these data are awaited.
Italics are mine.
> These observations suggest that we cannot assume COVID-19 vaccines, even if shown to be effective in reducing severity of disease, will reduce virus transmission to a comparable degree. The notion that COVID-19-vaccine-induced population immunity will allow a return to pre-COVID-19 “normalcy” might be based on illusory assumptions.
I can't sense any tone of favorable expectation in the link you shared.
Not necessarily:

People that don't know that might be confident they don't need to keep distance or wear a mask anymore.
