What is the key to a robust immunity against SARS-CoV-2? According to a study recently published in The New England Journal of Medicine, it could be a previous SARS infection—more specifically, the one that spread across 29 countries between 2002 and 2004—plus vaccination. 

As cases of the Delta variant continue to raise concerns across the United States, a new variant reaches a warning level for the World Health Organization.

In a survey released by oncology data leader COTA, half of the respondents pointed to “Operation Warp Speed” for the Covid-19 pandemic as the seed of their belief that cancer treatments can and should be moving forward faster.
