Conclusions and Relevance: This cohort study found that, among patients with obesity, substantial weight loss achieved with surgery was associated with improved outcomes of COVID-19 infection. The findings suggest that obesity can be a modifiable risk factor for the severity of COVID-19 infection.
Highlights
- Vaccination to prevent severe cases of COVID-19 is key to controlling the pandemic.
- Some vaccines may trigger rare autoimmune adverse events.
- AZD1222 is here reported to trigger relapses of MS and NMOSD.
Discussion: Most adolescents with MIS-C for whom vaccination was indicated in France had not been vaccinated. These results suggest that COVID-19 mRNA vaccination was associated with a lower incidence of MIS-C in adolescents. The median of 25 days between single vaccine injection and MIS-C onset compared with a mean 28-day delay between...

In this cohort study, receipt of the BNT162b2 mRNA COVID-19 vaccine during the second trimester of pregnancy was associated with maternal and neonatal humoral responses, as reflected in maternal and...
Conclusions and relevance: In this cohort study, receipt of the BNT162b2 mRNA COVID-19 vaccine during the second trimester of pregnancy was associated with maternal and neonatal humoral responses, as reflected in maternal and neonatal SARS-CoV-2 IgG antibody levels measured after delivery. These findings support COVID-19 vaccination of pregnant...
Among sequence-confirmed breakthrough cases, 10 were Delta and 9 were non-Delta infections. Among breakthrough cases, the median FRNT50 against WA1 was 4646 (95% CI, 2283-7053) vs 489 (95% CI, 272-822) for controls (950% increase; P
