Today, NIAID joins the world in a message of hope: “Yes!
SARS-CoV-2 Infection Weakens Immune-Cell Response to Vaccination
March 20, 2023
The magnitude and quality of a key immune cell’s response to vaccination with two doses of the Pfizer-BioNTech COVID-19 vaccine were considerably lower in people with prior SARS-CoV-2 infection compared to people without prior infection, a study has found. In addition, the level of this key immune cell that targets the SARS-CoV-2 spike protein was substantially lower in unvaccinated people with COVID-19 than in vaccinated people who had never been infected. Importantly, people who recover from SARS-CoV-2 infection and then get vaccinated are more protected than people who are unvaccinated.

Forgoing One Food Treats Eosinophilic Esophagitis as Well as Excluding Six
February 27, 2023
Eliminating animal milk alone from the diet of adults with eosinophilic esophagitis, or EoE, is as effective at treating the disease as eliminating animal milk plus five other common foods, a clinical trial funded by the National Institutes of Health has found. For people with EoE whose disease remains active after they forgo animal milk, a more restrictive diet may help them achieve remission, according to the researchers. These findings were published today in the journal The Lancet Gastroenterology & Hepatology.
