In every age group, COVID vaccines reduce the risk of severe disease or death by >90%. health.state.mn.us/diseases/coron…

The booster adds to this efficacy by reducing the number of cases. See 2 doses (red line) versus 3 doses (blue line).
So with the booster the difference between unvaccinated and 3 dose vaccinated will be even higher than what we have seen so far.

Just like anti vaccine folks found Gibraltar, another place they keep pointing to is Vermont, the most highly vaccinated state.

Best for people know the facts.

1) No state has done as well as Vermont in this pandemic: fewest lives lost. They know what they are doing. Image
2) Vermont is the best vaccinated state and vaccinations have kept deaths low. Since June 1 by which data everyone had an opportunity to be vaccinated, deaths have continued to stay low in Vermont. But have increased in many less well vaccinated states. Image
3) Even Vermont is not as well vaccinated as it should be. So 72% while #1 in the US is lower than many countries. There are vulnerable people and unvaccinated people, so with delta cases will occur.

Michigan COVID cases go higher than ever before. Only 54% in the state are fully vaccinated. Image
There are like 17 states with vaccination rates lower than Michigan.

Thanksgiving, Holiday season, and Winter are coming.
First things first. Get vaccinated if you haven't already. Get a booster if you are already fully vaccinated.

Vaccines prevent hospitalizations. A big deal in many ways, including because there are people with other illness who need beds.

Vaccines save lives.

US has lost more lives to COVID in 2021 than 2020. But 450,000 deaths were prior to Feb 1, before any effect of vaccines could have occurred.

180,000 deaths since June 1, the date by which adults in USA could have been fully vaccinated if they wanted. wsj.com/articles/u-s-c…
The 100,000 lives lost in last 2 months is the most distressing. Because 90% of these were preventable.
For a while there till September things seemed to be going well. Hard to watch.

Suddenly a lot of anti vaccine have found Gibraltar.

My response:
1) While a breakthrough wave is occurring, the ~100% vaccine rate is keeping COVID deaths at zero or near zero.

2) "Natural immunity" from higher infection rate compared to US didn't prevent present wave either. ImageImage
Messages:

1) 2 dose vaccine works really well in preventing deaths & serious disease.

2) We have vulnerable among us: elderly & immunocompromised, children less than 5 who cannot be vaccinated; and risks of long term Covid. So get a booster if offered.

3) Continue precautions
So instead of worrying about Gibraltar, or Malta, or Iceland, or Singapore or anyone else who has high vaccination rates — please get vaccinated if you haven't already done so.

Breaking: As I anticipated, FDA approves boosters for all adults. With cases rising this is the right decision. Boosters are highly effective. Please get the booster shot — it will help mitigate a big Holiday wave. apple.news/AobyvV5X2T1q3K…
While we are concerned about vaccine equity and rise of vaccine resistant mutants elsewhere, time is of the essence in controlling rise in cases in the US.

Boosters are highly effective based on real world (Israel, UK) and RCT data. No question. 👇
This trend is in the wrong direction. Worrisome given winter and Holiday season.

-Boosters will help, but we also need 3 more things:

1) More unvaccinated need to be vaccinated
2) Masks, ventilation, limit crowding indoors
3) Increased use of rapid tests for indoor gatherings Image

There is no question boosters work based on real world and RCT data. With 1000 deaths a day, it is highly likely that FDA and CDC will expand eligibility for boosters this week. @IssamAhmed news.yahoo.com/amphtml/everyo…
Things are moving fast. Several states have already expanded access to all adults. google.com/amp/s/thehill.…
