Until you've been exposed to a highly contagious disease prevented by an extremely safe vaccine, you have prejudice and 0 experience. I have experienced a Pertussis
outbreak in my own family, my sister even though she was vaccinated has an odd blood type, somebody from Idaho who wasn't vaccinated was having a coughing fit while purchasing something from her at her job at the mall. She became deadly ill and stayed ill for months. It was hard to diagnose and all of the top doctors missed it. She got help from the low income public service clinic who document movements of whooping cough much more stringently. Which says volumes about who gets exposed the most to these deadly diseases.
Her husband, daughter and son were all put on erythromycin
as a precaution. All of her close contacts for the initial 3 weeks she was contagious were notified. It's gravely serious what your saying and believing here, life and death serious. I actually believe you are the one who is callous.
