TL;DR: The mRNA-1273 vaccine as discussed by the authors is a lipid nanoparticle-encapsulated mRNA-based vaccine that encodes the prefusion stabilized full-length spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes Covid-19.

TL;DR: Once-daily oral daclatasvir plus sofosbuvir was associated with high rates of sustained virologic response among patients infected with HCV genotype 1, 2, or 3, including patients with no response to prior therapy with telaprevir or boceprevir.

TL;DR: A history of exposure to "moldy" hay, birds, or other incriminated occupational or environmental inhalants in a patient with clinical and radiologic features consistent with HSP should lead to the demonstration of serum precipitins to the suspected antigen and an established diagnosis, confirmed by avoidance of the agent involved.

TL;DR: It is demonstrated that patients with egg allergy, even those with significant allergic reactions after egg ingestion, can safely receive an influenza vaccine in a 2-dose protocol when the vaccine preparation contains no more than 1.2 micrograms/mL egg protein.

TL;DR: Two patients presented with histories compatible with an anaphylactic reaction temporally related to meals and detailed allergy and immunologic studies indicated that the episodes were caused by sensitivity to metabisulfites.
