Covid-19 Vaccines: Even After Getting Vaccinated, You Could Still Infect Others
FiveThirtyEight ^ | 12/20/2020 | Maggie Koerth

Posted on 01/30/2021 8:31:27 PM PST by SeekAndFind

Now that the world has successfully completed history’s fastest development of a new vaccine, you might be wondering why we don’t always just make one this fast. If the Pfizer and Moderna vaccines are safe and effective and the process to produce them didn’t cut any corners … well, why does it normally take around a decade to do something we just did in less than a year?

The answer to that question is inextricably tied up with another question floating around: Once you get the vaccine, can you just go back to your normal life full of hugging people and not wearing a mask?

If only we knew for sure. And we don’t know because there are some things that got skipped over when scientists went and made a vaccine faster than anyone thought possible. Nice-to-know details were pushed to the back burner in a rush to make sure the new vaccines would be safe and effective. And one of those details is whether the vaccines keep people from spreading COVID-19 or whether they just keep those who do contract it from getting sick.

“Theoretically, a vaccine should stop both the infection as well as the transmission and spread,” said Dr. Purvi Parikh, an immunologist with the nonprofit Allergy & Asthma Network and a co-investigator on the Pfizer vaccine trials.

But we don’t know yet if that is true of the COVID-19 vaccines, she told me. That’s because the focus of the clinical trials was narrow. It had to be because of the time constraints. Scientists wanted to know whether these things prevented illness. They wanted to know whether the drugs were safe. And they got those answers.

But getting those questions answered fast came at the expense of answering other questions — like whether vaccinated people can still spread the virus. “With a lot of other vaccines, you have years of data to analyze that,” Parikh said.

So, experts are being careful — balancing their excitement and relief with caution that you can’t just switch off 2020 Mode and return to a normal state of being. They need a little more time to know for sure.

If someone was protected from symptoms of COVID-19 but still capable of spreading it, it wouldn’t be that shocking. There’s a hypothetical mechanism that could allow this to happen biologically, said Deepta Bhattacharya, a professor of immunobiology at the University of Arizona. And that mechanism is … well … it’s boogers and phlegm.

“So, the virus enters in through the upper respiratory tracts, either through your nose or your throat. And those are protected by a mucous layer. And so that mucous layer is good at slowing things down from getting into you. But it also acts as a barrier for things like antibodies, and certainly for cells from getting out and meeting the virus as it comes in,” he said.

Even if a vaccine has trained your immune cells to kick the butt of any SARS-CoV-2 viruses they spot, they might not be able to neutralize the ones resting in your nose, on the other side of your mucous barriers. Those COVID-19 viruses wouldn’t hurt you, but they still might be able to replicate and shed — coughed back out of your nose and mouth and into the community, where they could encounter your unvaccinated friends and loved ones.

We also have at least one example of a vaccine that can end up protecting the vaccinated person more than the community at large, Parikh told me. The flu vaccines are notoriously imperfect in how well they protect against infection, as effectiveness rates fluctuate but tend to be between 40 and 60 percent. That’s better than nothing for the people who get them — especially because we know that, even if you do get sick, having had the vaccine can result in a less severe illness. But, Parikh said, that means that person — vaccinated, less susceptible, and less sick than they otherwise would have been — can still spread influenza around the community.

That’s the kind of thing scientists are worried about. But they’re also optimistic. “I suspect the answer will be that people will not be able to transmit — that the virus will protect from transmission, because I think there will be enough antibodies made that will neutralize the virus even at the mucosal surface,” said Dr. Warner Greene, senior investigator at Gladstone Institutes, an independent, nonprofit research lab in San Francisco. “But it is just a guess at this point,” he added.

It’s a guess Bhattacharya agreed with. The Pfizer and Moderna COVID-19 vaccines have, after all, turned out to be much more effective than those tricky flu vaccines. “If you have a vaccine that’s 95 percent effective at reducing symptoms, there is no universe in which it wouldn’t also reduce the likelihood of transmission. It’s just not possible,” he said. “So we’re not talking about whether it reduces transmission or not, we just want to get an extent as to how much.”

Figuring that out, though, is going to take some time. Bhattacharya and Greene estimated months; Parikh said six months to a year. So, it’ll be a little longer until vaccinated individuals can let their guard down. Even after you get your two jabs, you should wear a mask and avoid crowds and situations where you could spread the virus to a lot of other people.

The Centers for Disease Control and Prevention is sponsoring studies that involve looking at the households of vaccinated people to see what impact vaccination has on that kind of close contact spread, Bhattacharya told me. And researchers with Pfizer and Moderna will continue to monitor trial participants to see if they’re spreading the virus, Parikh said. But what we’re really waiting for is the real-world evidence that duplicates that study work.

“What would be even more powerful is once the general population, enough of the people get vaccinated, and then we really see the rates drop,” Parikh said. “That would be the greatest evidence.”

I got a slap-down from FacePlant for posting this very thing a few days BEFORE Jan 20. Maybe all is ok now, or has anyone tested the Fake Checkers lately???

I think FakeViews Falsie is recommending three (or is it now four?) masks.
At some point essentially zero covid will get in or out, but neither will Oxygen.

The two or three week stay home directive has not fully expired in some people’s minds.

Just give me the HCQ, some extra vitamins and a little Z-Pack and JUST GO AWAY

I am not getting a COVID-19 vaccine. I don’t care, there’s no way in (Nicholas Cage from the movie “The Rock” here) ZEUS’ BUTTHOLE! that a vaccine can be produced in mere months.
*****************************************************
I agree. And there sure as hell is no way that a Boeing 747 weighing over 700,000 pounds can ever lift itself into the air. Just not possible!

RE: WHY EVEN BOTHER WITH A VACCINE IF THE RISKS ARE WORSE THAN THE MARGINAL BENEFITS?

The only benefit I can see is the promise that you won’t get ill if you get infected.

The vaccine does NOT promise:

* immunity from infection
* inability to infect others

So, what does it promise? No bad symptoms.

If that can’t even be achieved, then the vaccine is useless for all purposes.

It doesn’t affect me. I will live and die without the vaccination. Not likely from this pretend Novel virus Covid though. I am immune, just like my President Trump.

You figured it out.

We are being played - or at least lied to.

I hear lack of oxygen kills the Coronavirus, thus solving the COVID-19 pandemic AND anthropogenic global warming!

Simple solution,,,,,,make both HCQ, Zinc Sulfate, Azithromycin and Ivermectin OVER THE COUNTER DRUGS so people can treat themselves. If treatment is started within 48 hours of the onset of a fever and cough the cure rate is almost 100%. Pandemic problem solved. The drugs have been around for years, with a proven track record ,,,,,what is the matter with the CDC/FDA????????????? The cost is nothing.........$18.00 for the Ivermectin and $50 for the HCQ,Zinc and Azithromycin..............

Well that about sums it up. NO VACCINE FOR ME

Let’s see here...........

The vaccine is developed for a mild cold like illness that has a very low mortality rate for most people even without treatment, and is even less lethal with proper treatment.

You need two shots for it to supposedly immunize you, but in spite of that,
-you can still get sick,
-still spread the virus,
-still must wear masks,
-still must socially distance,
-risk the side effects and whatever might happen if you actually catch the virus out in the real world,
-and they still want you to get the vaccine even if you’ve had COVID which would make you immune.

You have to ask yourself what the purpose of pushing the vaccine on someone who has had the disease really is, because that makes NO sense at all.

If the vaccine is not going to address the illness, then there’s no point in getting it.

Also to consider, is just who is pushing it the hardest and ask yourself if you trust them to really have your best interests at heart.

It is.

They should have those answers BEFORE putting out the vaccine.

And what a great way to monitor people. Makes Alexa and Siri seem like pikers.

Look at the studies done on animals and what happened to them after the vaccines when they encountered the virus for real in the real world.

The mortality rate was through the roof.

Demorats have made Covid such a political issue that they're dictating what can be made known and not to the public. This according to a major hospital in my area by those administering the vaccine to their medical staff.

They were asked if you can give covid to some else after you've been vaccinated....”they specifically said to the staff member...”we're not suppose to say but NO once you're vaccinated you can't spread it to anyone else”..

Likely because the after symptoms are also bad if you happen to get it. Some go on for months enough to prevent people from returning to work......this is for those with just light or moderate cases of covid and no underlying illnesses. rather healthy beforehand.

Apparently some believe covid hypes the immune system so high that it doesn't calm down for a very long time and could be the cause of these after symptoms. A couple of people affected said the after symptoms were worse than how they felt with active covid.

“what is it actually doing??”

According to the trials, many fewer vaccinated people had minor covid symptoms, vs placebo people.

In Pfizer, for example, 9 out of 21,500 placebo people had hospitalizable symptoms. 1 out of 21,500 vaccinated people had these major symptoms. No one died. In other words, the vaccine is effective in the tiny chance someone’s immune system can’t handle a bad covid viral load.
