News flash...a lot of people who go to pharmacy school don't go with the explicit thought of helping people. A lot do, but it's not as overwhelmingly the majority as you would find in med school or nursing school, where more "direct" patient care is what students signed up for.
That said, I think it's reasonable for vaccination pharmacists to be concerned about not being offered a vaccine. Risk is relative. They're not in a position to work from home, so they're at a higher risk than the many who can work remotely. From a practical standpoint, any vaccinating pharmacist that gets infected won't be available to administer shots for a few weeks at best. Even worse, those high risk people coming to get shots will be at risk of contracting the virus from them during the asymptomatic phase...before the vaccine has time to be effective. FWIW, I don't practice and I don't expect to have the opportunity to receive the vaccine until at least late spring. I don't think its so cut and dried though. From mortality risk standpoint, there are populations that are undoubtedly higher than vaccinating pharmacists. In terms of work force though, for the country to go back to full re-opening...many (or majority) are under 65. These consist of the main population who care for and in many ways financially support the high risk populations. The faster the work force population is vaccinated, the sooner everyone's life (including higher risk populations) goes back to normal.
