Fair points Gary, but two things are still an issue (in my mind).
1 - The vaccinated people that still catch it (whether mildly, or severely), we don't know if those individuals might potentially suffer from 'long haul' effects. Only time will tell.
2 - You can't convince me that there won't be a "US variant" at some point in the future. With many southern states as low as the low 30% of fully vaccinated people, I firmly believe it's a matter if when, not if it will mutate in the US.
The Delta variant is something to be 'concerned' about - not nearly to the extent the world was/should've been with the original strain at the start of the pandemic, but it is still something that is going to cause a lot of sickness and death still.
I think there's over 4000 covid variants. I'm sure many of those are from the US. It's just a matter if the variant mutates in a way to make it more dangerous. I have still not seen any data to say any variant is more "deadly" than the other. There's lots of data to show ones like Delta are more contagious though and because of that, they become dominant. A US version could become dominant at some point, but a bit less likely due to the overall high vaccination rate. I read something today that even breakthrough cases of infections, those people aren't likely to create a variant because generally the viral load is too low, similar to how vaccinated people aren't likely to spread covid.
The only concern to me, are the people who don't get vaccinated because of bogus reasons, not the variants themselves. The reason this will drag on and more and more people will die is because of people choosing not to vaccinate and the people who can't get vaccinated (whether due to age, health issues, or no access to a vaccine... all legit reasons that the bogus people can very much help with)
Having said that, NJ has reported no deaths today. Hospitalizations are at all time lows since this started. Yes, there are still infections happening, but very small amounts. NJ is ranked around 7/8 in states for vaccinations. "the proof is in the pudding" as I've said time and time again with these vaccines. They work, the data shows this. The side effect risks are very much worth it. I know this all falls on deaf ears to the anti vaxx people, but I can't help myself from expressing this.
