Hey I want to start a cna class. i understand that i need a physical exam before we start the clinical part of the class,but i don't have any insurance. i am willing to pay for the physical but if im correct blood work is expensive i cant pay for that and im not sure what vaccinations i would need for the class has anyone attended a class before and can tell me what vaccinations they needed to get? i don't want to start the program and then go to get a physical and find that i cant afford it and have to leave the class. any advice
