Hello again, dear readers, and welcome to our monthly letters column. We’re happy to hear that our recent focus on your questions regarding the coronaviru­s vaccines has been helpful. Keep sending them in, and we’ll keep addressing them. Speaking of which:

-- A reader with a petite friend wondered whether coronaviru­s vaccines should be tailored to a person’s physical size. “My neighbor weighs 94 pounds and worries she might get too much vaccine with a standard vaccinatio­n,” she wrote. “Should she get a smaller dosage?” Adults of all sizes can safely receive the same vaccine dose. Although medication­s are calibrated to reach certain blood concentrat­ions based on body weight, the coronaviru­s vaccines “speak” directly to the immune system. That means the dosage remains constant, no matter a person’s size. Your neighbor can safely receive the standard dose of any of the three coronaviru­s vaccines available in the United States at this time.

-- Many of you who are about to get a coronaviru­s vaccine wanted to know when maximum immunity kicks in. According to the Centers for Disease Control and Prevention (CDC), you’re considered to be fully vaccinated two weeks after the second shot of the two-dose Moderna or Pfizer vaccines, and two weeks after the single-shot Johnson & Johnson vaccine.

-- Another frequently asked question is whether it’s OK to get the coronaviru­s vaccine at the same time as other vaccines. Just as a precaution, the current recommenda­tion is that the COVID-19 series be administer­ed alone, with at least a two-week interval before and after any other vaccines.

-- Some of you weren’t sure whether the vaccines contained ingredient­s to which you have known allergies. “I am severely allergic to povidone, which is frequently seen listed as an inactive ingredient in both overthe-counter and prescripti­on medication­s,” a reader wrote. “Is this a cause of concern with the COVID-19 vaccines?” Polyvinylp­yrrolidone, also known as povidone, or PVP, is a water-soluble synthetic polymer that helps keep drugs in suspension. We have reviewed the COVID-19 vaccine ingredient­s and do not see povidone listed.

-- A reader whose son recovered from Guillain-barre syndrome (GBS) as a child asked whether the coronaviru­s vaccine is safe for him an adult. Persons with a history of GBS may receive the COVID-19 vaccine unless they have been previously instructed to avoid vaccinatio­n. As this is the case with your son, who has been advised to avoid the flu vaccine, be sure to check with your health care provider for specific recommenda­tions before moving forward with coronaviru­s vaccinatio­n.

We’ll close with a reassuranc­e to those of you who ask that your names not be used in the letters column. We do not publish the names of our correspond­ents. However, we do love picturing where you’re writing from -so if you’re willing, feel free to include your city or state in your emails. As always, thank you to our readers who have taken the time to send kind and encouragin­g words. It really does mean a lot to us.
