These things will work for an adult but if you’re talking about refusing a vaccine for your kids that is part of the CDC schedule for school, they do not work. It depends on your state laws. Also, be prepared to be dressed down by the doctor and nurses and kicked out of the practice altogether if you refuse a vaccine. Some of them get really worked up about it. Also, not all the vaccines have MRC-5. There are two different aborted fetal cell strains used in vaccines. One female and one male IIRC.
