Nearly four months since the first COVID-19 vaccines were given to health care workers, distribution has slowly built to a network of 770 vaccination sites, many of them chain pharmacies. While there are primary care doctors’ offices who have entered the fold, there’s frustration voiced by such family care practices that their pre-existing relationships with patients aren’t being prioritized as a point of vaccination. “Primary care physician practices are receiving hundreds of calls each day from their patients asking if their practice has the vaccine and, if not, if they can be put on a list just in case they receive any,” the New Jersey Academy of Family Physicians said in a written statement received Thursday by New Jersey 101.5.
