Should you laminate your vaccination card?
According to several sites, it may not be a good idea to laminate your COVID-19 vaccination card. Why? The ink on the vaccination card can become illegible.
Some cards the label is placed on the card mentions the vaccine brand and lot number. Those have been printed on thermal printer labels. If you put that through a thermal laminator, they will be completely black and illegible.
Instead, CDC officials recommend making photocopies of the card and taking a photo of your original.
