361 - Friday Q&A With Dr. Amesh Adalja

<p>I am fully vaccinated with the Moderna vaccine. If I catch the delta variant will I acquire additional immunity—in addition to the immunity to the vaccination? If I received the COVID-19 vaccine and I’m now breastfeeding, will my baby receive antibodies? Do masks get less effective depending on how long they’re worn?</p> <p><strong>Dr. Amesh Adalja</strong> of the Johns Hopkins Center for Health Security addresses your questions submitted to publichealthquestion@jhu.edu.</p>
