I cannot keep vaccines straight in my mind. It’s easy for them to run together in my ol’ gray matter, especially vaccination schedules.
Thankfully, there’s Vaccines.gov, which covers anything and everything related to vaccines. It is a great site for healthcare professionals and the lay public alike, as it covers basic information, schedules, vaccinations for travel, glossaries, descriptions of mechanisms of action, and more. It’s nice to have such a resource handy.
