I've already disproven this.
The ONLY free vaccines are the season flu.
Not MMR, not Tetanus, not COVID, not etc.
ONLY the flu is free from FOUR SEPARATE HEALTHCARE SYSTEMS I checked on, and checking with friends and family in other fields, the flu is only at about 70ish percent of them for free not using their insurance.
ALL other vaccines are on your dime and/or through your insurance, which are at 100% through their insurance if coded as routine/preventative.
Be it healthcare system, whatever other term you want to throw out for medical personnel, and/or non-healthcare employers.
There's no federal mandate or law requiring.
If they want to out of the goodness of their corporate hearts, ah salute.
YOUR employer offering ALL the vaccines for free is the anomaly/exception, not the rule or standard.
