SARS-CoV-2 mRNA vaccines elicit higher levels of antibodies compared to natural infection

Researchers from the US recently characterized the scale and specificity of SARS-CoV-2 spike-reactive antibodies from 23 participants who received SARS-CoV-2 mRNA vaccines and 10 acutely infected health care workers. They found that primary mRNA vaccination and infection elicited S1- and S2-reactive antibodies, while secondary mRNA vaccination elicited mostly S1 antibodies.

Is gout a risk factor for COVID-19?

A team of international scientists has recently determined the association between gout and risk of coronavirus disease 2019 (COVID-19) related death in a large cohort of patients. Their findings reveal that gout can significantly increase the risk of COVID-19 and related mortality, with women having a higher risk than men. The study is currently available on the medRxiv* preprint server.
