What this 105-year-old woman credits for helping her survive Covid-19. Lucia DeClerck is 105-years-old, and on Jan. 25 (the day after she received her second dose of Pfizer's and BioNTech's Covid-19 vaccine), she learned she tested positive for the novel coronavirus.

That's because your vaccine card has your full name, birthday, and other valuable information on it that could make it easier for scammers to figure out most of your social security number, Maneesha Mithal, FTC's associate director for the division of privacy and identity protection, told the Times' Christine Hauser, who recently spoke with experts about the countless reasons why you should keep your vaccine card to yourself.
