The layered approach is the best way to reduce your chances of getting #COVID19. It's not just one mitigation. Layering multiple mitigations will help prevent you getting it or spreading it: masking, distancing, going virtual, air purifiers, ventilation, Far-UVC, and vaccines all add up.
We are SO grateful to everyone who's fighting back on COVID disinformation and providing support and factual information about airborne pathogens and clean air. Thank you to everyone working for a better world! What are YOU grateful for this season?

We are up to 688 LoCITT participants!
If we could enroll all 1,000 participants within a month of launch (by 11/30), it would send a powerful message about the demand for remote Long COVID clinical trials.

I ran across this 1896 editorial in a medical journal.
The author is discussing a smallpox outbreak in Gloucester, England (pop 42,000). The town was a hotbed of anti-vaxxers until there was a massive outbreak.
At that point, 25,000 people lined up for smallpox vaccines.

Get vaccinated. But also know that, while helping prevent serious illness in the initial acute phase, in some cases COVID vaccines may reduce the risk of infection only by roughly 30% for 2-4 months. And they don’t prevent long term issues. So that’s where the need for masking comes in
Some vaccines like COVID and flu don’t stop completely stop infection.
But they do reduce the risk of getting infected and greatly reduce severe illness risk.
They are still worth getting.
Since they are not 100% effective it’s also wise to add another layer of protection by wearing a mask.
