It's important that people who already had Covid also get vaccinated. A study from Denmark suggests that previous infection provided 80% protection against reinfection, but protection among those age 65 and older was only 47%.
A study funded by Gilead Sciences evaluating the use of its drug remdesivir to treat 53 seriously ill COVID-19 patients found that some got better.
But there was no control group, so strong conclusions weren't possible. https://t.co/QHa084jNth
