NEW: #COVID19 vaccines will probably prevent you from getting sick. No one knows yet whether they will keep you from spreading the virus to others — that information may be available in a few weeks. 1/7 https://www.nytimes.com/2020/12/08/health/covid-vaccine-mask.html
This information is crucial for vaccinated people because, as @ImmunoFever said: “It’s really going to be critical for them to know if they have to keep wearing masks, because they could still be contagious.” 2/7
Why would a vaccine protect from serious illness but not from infection? Short answer: because it's injected into the blood, and infection usually begins in the nose. That's where the antibodies and immune cells would need to be to fight the virus right on entry. 3/7
So why don't we vaccinate people in the nose (like the FluMist)? Good question, why don't we? Those vaccines are coming. But in the meantime, there's promising evidence that antibodies in the blood do make it to the nose. 4/7
Also promising: these vaccines are so highly effective that even if they don't prevent infection, they will probably suppress the virus to such low levels that vaccinated people won't be able to transmit it to others. 5/7
We just don't know for sure yet so until we do, vaccinated people should still wear masks and socially distance. The companies are all doing tests now to figure out whether the vaccines also prevent infections and, if so, how well. 6/7
How will they test for this? And when? I've received dozens of emails about this, so I know you're curious and will want to read the article
