Annual vaccinations? And that's okay to you?
I mean, I'm not knowledgeable about the science etc but if yearly vaccinations are necessary then yes that's an inconvenience.
But then it beats dying or getting sick or transmitting a deadly virus so yeah it's ok to me.
Nobody is doing this for fun. There's very little if any malice here. It's not someone deciding to screw the people by just saying yearly vaccinations haha !
It'll take what it takes.

Yep, that would be the next frontier -- a therapy.
For the time being, we need to keep spreading the word about getting vaccinated, so that hesitancy can be reduced as much as possible.

In answer to your second question:
I can tell you right now that reinfection after a bout of Covid happens infrequently (sometimes due to a variant), and infection after full vaccination is ALSO very infrequent. I will find you the exact numbers - but it is extraordinarily unlikely.
Found it - as of 4/20/2021:
“Walensky said that of the 84 million people who have been fully vaccinated in the United States, fewer than 6,000 have gotten sick with COVID-19 more than two weeks after being fully dosed. Of those, nearly 400 were hospitalized and around 75 died, according to CDC data. Some of the hospitalizations and deaths were not due to COVID-19 infections.”
6000/84,000,000 = 0.007% Low enough for you?
PS I apologize for sounding haughty before.
No problem. The stuff you posted is encouraging that vaccinated people are rarely going to get full blown covid, or even asymptomatic covid, This will greatly reduce spreading. And yes, .007 is very low, but as you said, the covid reinfection rate out of the 32 million cases is also rare and that percentage should be just as low if not lower. It's safe to say that both methods work, and as far as which one being better, there may just need to be more time passed as we go further months into the post vaccine research, to be able to tell which protects you more.
Yup. But the sophisticated immunologic data to date suggests/predicts that, in the case of Covid, vaccination is better than natural infection in producing sustained immunity.
Do you know if they can add multiple strains of the covid variant into 1 shot, like they do with the flu shot?
Absolutely.
The mRNA platform for the Pfizer & Moderna vaccines can be readily modified to produce a vaccine which better protects against important variants. The process already began a month or 2 ago. I believe that annual Covid vaccinations are in our future.

Practically if not technically, these drugs sound a lot like the current vaccines, no? I mean I guess there's a clear difference between developing antibodies versus being injected with them, but I imagine the end effect should be similar.

Also Rochelle Walensky, a couple weeks later...“I would encourage people to continue, once they’re vaccinated, to use all the prevention measures that we’ve been talking about when they’re outside their home, including masking and distancing and whatnot.

For the record, it's clear that the vaccine, at the least, meaningfully reduces transmission (by decreasing asymptomatic disease) and significantly reduces the consequences of infection (severe disease)
AND dramatically decreases de novo PCR + symptomatic or asymptomatic disease - both in the clinical trials & MULTIPLE*** real world post-emergency approval studies.
***and here is the citation for 1 of those real world studies published in the world famous NEJM on 2/24/2021 - https://www.nejm.org/doi/full/10.1056/NEJMoa2101765
That's fine by me and I'm not worried about whether the vaccine by itself prevents transmission as well as some studies show (or as well as Rochelle Walensky claims).

The proverbial cow would already be out of the proverbial barn.
As you know, there already is a bushel of epidemiologic data demonstrating a marked reduction in the mean age of hospitalized Covid patients - consequent to more VAX of older people.

How often do you see Covid-associated coagulopathy? How closely does it overlap classic DIC?
How are you treating it?

COVID‐19 coagulopathy: is it disseminated intravascular coagulation?
Marcel Levi and Toshiaki Iba
Received: 5 November 2020
Abstract
One of the significant complications of severe COVID-19 infections is a coagulopathy that seems to be related to the occurrence of venous and arterial thromboembolic disease. The coagulation changes mimic but are not identical to disseminated intravascular coagulation (DIC). The vast majority of patients with COVID-19 do not meet the criteria for usual forms of DIC. In addition, there seem to be features of a strong local pulmonary thrombotic microangiopathy and direct endothelial cell infection and injury by the virus that affect the coagulopathic response to severe COVID-19. It seems COVID-19 leads to a distinct intravascular coagulation syndrome that may need separate diagnostic criteria.
How does Covid-associated ARDS compare with classic sepsis-associated ARDS?
To the best of my knowledge, we are the only docs who regularly post here.

There's certainly is a pro-thrombotic propensity; our approach has been to follow daily d-dimers and adjust heparin/lovenox as needed. In terms of a DIC-like disease, we see some similar markers but so far have just been chalking it up to a consumptive coagulopathy associated with sepsis (seems like what the article suggests)
Covid ARDS has some differrences - main things are that they seem to have lower airway pressures and better compliance than classic ARDS. Early on there was a suggestion that certain modes of ventilation (mainly bi-level) shouldn't be used in covid, but thats since been disregarded and for all intents and purposes the two are managed similarly now.
On the back end, a lot of the intubation survivors have to wait far longer than usual for their vent needs to be low enough to safely trach (4-6 weeks or longer), so post LTACH we're seeing a lot more issues with tracheal stenosis, granulation tissue and other airway problems.

You categorically stated a few days ago that “there's no factual evidence that vaccinated people can't transmit it.” You apparently did not think that there was any evidence that vaccination was effective in curbing the spread of Covid by asymptomatic patients (beyond the fact that vaccination DRAMATICALLY diminishes symptomatic & severe disease both in the clinical trials & MULTIPLE real world post-emergency approval studies).
And I told you at the time that was untrue & that there is excellent peer reviewed evidence accruing suggesting that vaccinated people are much less likely to transmit the virus.
Enclosed below are TWO excellent publications indicating that vaccination indeed decreases asymptomatic infection - thereby, by extension, dramatically decreasing the likelihood of fully vaccinated people spreading the virus.
1. A study published on 5/6/2021 in the prestigious JAMA:
https://www.mdlinx.com/news/covid-19-vaccine-is-associated-with-fewer-asymptomatic-sars-cov-2-infections/1wwq9821YdVUL0BYD1i8k0?show_order=6&tag=Evening&utm_campaign=ealert_050721&ipost_environment=m3usainc&utm_source=iPost&utm_medium=email&iqs=9z2zoi6evkikkj3fenpskqk5uuv2j5k66lbh7t77l9g
“Protection was even greater for employees who completed two doses. A week or more after receiving the second dose, vaccinated employees were 96% less likely than unvaccinated workers to become infected with SARS-CoV-2. When researchers looked just at asymptomatic infections, vaccination reduced the risk by 90%.”
2. CDC in 4/2021
https://www.cdc.gov/mmwr/volumes/70/wr/mm7013e3.htm
"Our data from the CDC today suggests that vaccinated people do not carry the virus, don't get sick, and that it's not just in the clinical trials but it's also in real-world data," CDC Director Dr. Rochelle Walensky told Rachel Maddow on Monday, March 29.

I hope this information somewhat allays your concerns.
