I'll probably get it IF I don't have to give THEM my DNA.. So far EVERYONE who has been 'swabbed' ( testing for 19) , HAS given the guv, every 3 letter dept, drug companies, insureance companies and others their DNA. In fact , anyone who wants it can just buy your code of life...
Jay, it is relatively unlikely that DNA is being extracted from the nasal swabs used for testing for COVID. It would require coordinated dishonesty at several levels, from the fluid sample when the swab is collected on up through handling in the lab, and including the reporting. The newer rapid test is read immediately, and perhaps you could demand to see it disposed of after it is read, if you ever have to have one at the ER or urgent care. There will soon be on the market a recently approved home COVID test kit, and that would leave the sample entirely in your hands. This is different from the antigen test kit Flip mentioned, and which tells you if you have had the virus.
Re: the vaccinations and the video (I hate made for tv dog and pony shows), when it comes to your personal vaccination you can demand (well ask nicely) to see the vial from which the vaccine is drawn. Memorize and write down what the label is on it. I can imagine situations where they are doing assembly line vaccinations that someone will be in charge of filling the syringes and lining them up on a tray, the vaccine is precious and has to be thawed out in batches. Not sure the volume to be used, but could be very small.
Anyway always watch! I had a new “nurse trainee” give me vitamin B12 instead of a flu shot once. The office called me a few hours later to tell me. I had repeated when the guy came in “this is the flu shot for old ladies, right?” He said it was, I was suspicious because it was purple, and I’d never seen a purple flu vaccine. Good thing it was only B12. I have not ever let that doctors office forget it either.
