Low risk of second allergic reaction after SARS-CoV-2 vaccination

In a recent investigation posted to the journal JAMA Internal Medicine,* researchers estimate the risk of a repeated allergic reaction to the second severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) messenger ribonucleic acid (mRNA) vaccine dose in those with a history of allergic responses following the first dose by conducting a systematic review and meta-analysis.

Study shows Pfizer-BioNTech booster protects over 65s against Delta and Omicron

New research in nursing home residents found that a third dose of the Pfizer-BioNTech COVID-19 vaccine was effective for at least three months in protecting against the Delta and Omicron variant. While two doses of an mRNA COVID-19 vaccine showed poor neutralization to Omicron than Delta, a booster shot increased neutralizing antibody responses.
