We would all like to know this, including the scientists. It is being studied as we speak, and every few days more is known and released.

Remember that in terms of studying a disease, seeking effective vaccines and treatments, and understanding the mutations, more has been done on Covid in 20 months than in many years on other illnesses.

People are confused about many aspects, especially surrounding vaccination.

The current science, as reported, shows that SOME immuno compromised people did not have a full immune response to 2 cases, and a 3rd injection is recommended now. These are largely people who have had a transplant or take immune suppressing meds for another condition.

There is also emerging evidence that immunity begins to decrease after a period of time, currentl estimated to be about 8 months, and a booster may be in order for some people. The plan for this is not final.

Infections of immunized people are constantly being monitored and studied. Depending upon whose numbers you use, vaccination is 95% effective against early forms of Covid and 65-90% against the Delta variant.

However, the vaccines are more effective than that at preventing serious illness or death. The percentage of people hospitalized for Covid in Minnesota in recent weeks is 10% vaccinated, 90% unvaccinated.

Good morning- I'm not sure what are asking. I think that you are asking if current vaccines protect as well against Delta as it does for the other variants and covid-19.. The CDC has written:

"The COVID-19 vaccines authorized in the United States are highly effective at preventing severe disease and death, including against the Delta variant. But they are not 100% effective and some fully vaccinated people will become infected (called a breakthrough infection) and experience illness. For such people, the vaccine still provides them strong protection against serious illness and death."

Since there is not an approved test as yet to see how protected we are it's hard to answer that question, if that is also a concern. But it would be great to know, right?

Please mask along with vaccinating! "Although vaccines are highly effective, they are not perfect and there will be vaccine breakthrough infections"

I second what Sue reports that there is ongoing research to see how the Delta variant holds up. But, remember, it has been a short time. I tend to forget that. Just not enough time has passed to know or have an answer.
