Just read an article that the Pfizer vaccine is 85% effective after the first dose (after 2 weeks). Has anyone seen this study.
I have read that, but you can read almost anything you want on the web, the hard part is finding accuracy, which even pros are still working on.
I have also read that Pfizer, Moderna and J&J are all 100% effective against hospitalizations and fatalities.
I don’t know if that’s true, but I took my chances with Moderna.

My endocrinologist it at Duke. maybe I should drive an hour to get the shot over there if he can arrange it. how ridiculous is that?
It's worth a phone call to your endocrinologist. The office staff may have access to Duke's vaccine schedule.

Just read it an hour ago on the MSN website.
Just read the article. Good news! Always a qualifier...see the end here...
'The results might differ from others because the subjects were largely younger and healthier, said Gili Regev-Yochay, another of the authors. She also said the study couldn’t confirm how long protection from one shot would last, as most of the subjects received a second shot.'
Initial reports had indicated almost full immunity after the 1st shot for 24?-49 year olds. But this group is not the 'vulnerable' group. So, more information is needed regarding the efficacy for those who are most vulnerable before the 2nd doses 'run out' or the supply ramps up.

This is not exactly true.
The data Pfizer presented to the FDA stated that after dose #1, efficacy was estimated at 82%.
However, the observed efficacy after dose #1 and just before dose #2 was only 52.4%.
Pfizer concluded that their data "cannot support a conclusion on the efficacy of a single dose of the vaccine."
Here is a link to the full report Pfizer presented to the FDA:

If anything, read the last paragraph on page 32.

I'm gonna do that today. It's ridiculous though. I'm going that have to make two trips to Durham (total of 4 hrs driving) if it's possible to do so. And then I should be happy about it. LOL

All vaccination aftereffects are related to the biology of the person receiving the shot. So, it doesn't matter what experience anyone else has. Your friend's experience will be unique to her, not what someone else experienced. Tell her to quit worrying and get the shot!

I have read this study dated Dec10. I had thought the 52% number was correct. This is an ongoing study and they are learning new things everyday. I am hoping this is a revised number from the Dec 10 study. My point being that I have only received my first dose. If the 85% number is true I would gladly give up my second dose appt to some other Sr. who cannot get an appt. so they get some level of protection. So many at risk people have not been lucky enough to get their first dose. I could wait till the others get their first. Then get my second. We all need to unite and help each other out. We need unity in our nation again. We are all in this together. Dr. Tom

My wife and I have gotten both shots, the Moderna variant. With the first, minor upper arm/should soreness on the second day then fine by the third. With the second shot, we hydrated the days before the shot and 12 hrs after the shot, took a ibuprofen as recommended by the nurse who administered mine. No discomfort whatsoever except for an extremely mild tickle at the needle spot. Easy, peasy....

An Israeli study in the Lancet just recently provided this 85% number.

Here's a link to the Israeli study for those interested:

They studied healthcare workers, whereas the Dec 10 Pfizer data was based on a broader spectrum of population demographics. It may not be appropriate to assume that the experience in healthcare workers may be applicable to the population at large. By definition, healthcare workers are young enough and healthy enough to work. The 85% efficacy in particular may not be applicable to the most vulnerable to Covid-19, namely the elderly and the significantly chronically ill. And may not apply to the very young. At least for now, the 85% efficacy only applies to healthcare workers and similar demographics.
What is needed is a study measuring both antibody levels and incidence of Covid-19 infection over 1 year in a broad spectrum cohort who receive only a single dose. Until then, the data are interesting, but not sufficient for generalized policy making.

I guess we can both agree we need more time and more studies. Second dose controversy is also a problem. Experts disagree if we should vaccinate more and do the second shot later. Also some say if you have had the virus you need only one dose. Dr. Fauci disagrees with doing this. My friend worked with Fauci and he has never met a more brilliant and respected individual. The UK is doing this with a different vaccine that actually would increase efficacy the longer time between doses. This is a very fluid situation and everything will change from day to day. Stay tuned!

Mywife is commenting on ill-feeling after her 2nd shot. My #2 is due Feb 27.
