It says "Report your work! Be sure to fill out the Doorknocking Spreadsheet with the counts of who still needs a vaccine, who is already vaccinated, who needs more info, etc. This is important information that the Health Department is relying on!"
LIE. They will put you on a f*cking list. They're clearly using this to get people to voluntarily offer their vaxx status and overcome medical privacy laws. Plus, maybe if their numbers are fakely inflated, they'll stop this nonsense.
And when they cross reference your name with your State's Health Dept and find out you were lying, they will return and ask you why you lied. You'll still be out in the correct category.
Better to tell the truth and fight standing up, than to lie thinking you're "bucking the system." They system is great at finding the dissenters and punishing them for their insolent lies.
