"<p class='article-card__paragraph-start'>The first two COVID vaccines developed by Pfizer and Moderna each require two (2) doses of the COVID vaccine. Each dose must be of the same product, and will need to be separated by either 21 days or 28 days, depending on the vaccine. That means if you received your first dose of the Pfizer vaccine, your second dose must also be the Pfizer vaccine. The Johnson and Johnson vaccine, approved for use in the US on February 27, 2021, only requires one dose. Consult your healthcare professional if you have additional questions.</p>"
