Why are we seeing more vaccinated people becoming infected with the Delta variant?

[elleng]

How protective are the vaccines at this point?

(from Calvert County, MD)

'Both of those questions have been on a lot of people’s minds since the Delta variant took hold and more breakthrough cases began to appear. Almost all COVID cases in Maryland are now caused by Delta. This variant multiplies much more quickly and at higher concentrations in the respiratory tract than previous COVID strains. Previous strains usually took 5-6 days from the time of exposure until people began to feel sick. It’s more common for symptoms from Delta to begin 3-4 days after exposure to an infected person. Studies have detected 1,000 times more virus in the nose and upper respiratory tract in early Delta infections than with previous strains of COVID.'>>>

1. I think that some vaccinated people don't believe they can get the virus so they don't wear masks.

Well, they are wrong.

2. Fauci

this morning said no vaccine is 100% and we are going to be seeing breakthroughs. He is concerned about a variant that outsmarts all the vaccinated. HOOLY SHIT.

6. I don't think we are anywhere near a 100% here.

4. Because being vaccinated never meant you wouldn't get covid?

5. I am not sure what the actual number is for how effective vaccines are against infection.

What seems clear that it's not 95% shown against original virus in clinical trials, but likely a lot lower.
