text:  The St. Christopher Truckers Relief Fund offers free flu, pneumonia, and shingles vaccine vouchers for all uninsured over-the-road truck drivers with a current Class A CDL. Vaccine vouchers can be used at any Walgreens or Kroger store. A copy of your Class A CDL is required with your voucher to receive your vaccine. Go to truckersfund.org under the Health and Wellness tab to get your voucher today. Again, that's truckersfund.org.
