What is this summary about?This is a summary of an article about part of a clinical study for the BNT162b2 COVID-19 vaccine, also called the Pfizer-BioNTech vaccine. The article was published in the New England Journal of Medicine in September 2021. The part of the study described in the article began in July 2020 and is ongoing. This means that the final results may be different from the results included in this summary.What happened in this study?The participants in this study received 2 injections of either the BNT162b2 vaccine or a placebo, 21 days apart. The placebo looked like the BNT162b2 vaccine but had no active vaccine in it. None of the trial participants or study teams knew who received vaccine or placebo.What were the results?Most of the reactions to the injections were mild or moderate and lasted for a short period of time. The most common reactions were pain at the injection site, extreme tiredness (fatigue), and headache. These reactions usually happened in the first 7 days after receiving a vaccine dose. A small number of participants had severe reactions to the vaccine.Compared to participants who received the placebo, participants who received the BNT162b2 vaccine were much less likely to become ill if they were infected with the virus that causes COVID-19. The vaccine also had very good efficacy at preventing severe COVID-19.Participants in South Africa who received the BNT162b2 vaccine were less likely to become ill after infection with the beta variant of the virus compared to participants who received the placebo. The beta variant was very common in South Africa when the study was taking place.

We describe the clinical characteristics and outcomes of 16 children and young adults with severe acute COVID-19 who were treated with tocilizumab. Patients who were discharged by day 28 were more likely to be treated with tocilizumab earlier in their COVID-19 illness and had lower ferritin and interleukin-6 levels compared with those who were not discharged by day 28.

Background. Effective therapeutic agents for the treatment of COVID-19 have been investigated since the onset of the pandemic. Monoclonal antibodies targeting the spike protein of SARS-CoV-2 have been developed for treatment of mild or moderate COVID disease in high-risk populations. Despite widespread use in the adult population, data are limited on the safety and efficacy of monoclonal antibody infusions in the adolescent and young adult population. Methods. Patients who received bamlanivimab, bamlanivimab-etesevimab, casirivimab-imdevimab, or sotrovimab for treatment of mild COVID disease at Cincinnati Children's Hospital Medical Center from 5/1/2020 through 3/1/2022 were identified retrospectively. In accordance with the FDA EUA, patients were eligible for monoclonal antibody administration if they were >=12 years of age, weighed >=40kg, and were at high risk of progressing to severe disease or hospitalization. Results. Ninety-four patients received monoclonal antibody therapy, of which 14 (13.5%) received either bamlanivimab or bamlanivimab-etesevimab, 54 (51.9%) received casirivimab-imdevimab, and 26 (25%) received sotrovimab. Ten patients (10.6%) experienced one or more adverse events. Of those, 2 (14.3%) received either bamlanivimab or bamlanivimab-etesivimab, 7 (12.9%) received casirivimab-imdevimab, and 1 (3.8%) received sotrovimab. Most common symptoms include rash, nausea, and throat irritation (table R1), the majority (90%) of which were mild, either self-resolving with infusion cessation (60%) or persistent but requiring no medical intervention (30%) (table R2). Of the patients who experienced adverse events, only 1 (10%) received medical intervention - epinephrine. No life-threatening events or deaths occurred. Within 90 days of receiving a monoclonal antibody, 15 patients (15.9%) required additional medical care for ongoing COVID symptoms (table R3). Eight (53.3%) of these were either hospitalized or received escalation of care while already in the hospital. Classification of adverse events by grade and monoclonal antibody. Grade I events are defined as mild and generally not bothersome. Grade II events are defined as moderate: bothersome, but not dangerous. Grade III events are defined as medically significant, but not immediately life-threatening, and often require medical intervention. Patients who required additional medical care for ongoing COVID-19 symptoms within 90 days of receiving a monoclonal antibody. Conclusion. Overall, monoclonal antibodies are safe, largely well-tolerated COVID-19 therapies in high-risk adolescent and young adult populations.
