Here’s Why Vaccinated People Still Need to Wear a Mask

The new Covid-19 vaccines from Pfizer and Moderna seem to be remarkably good at preventing serious illness. But it’s unclear how well they will curb the spread of the coronavirus.

That’s because the Pfizer and Moderna trials tracked only how many vaccinated people became sick with Covid-19. That leaves open the possibility that some vaccinated people get infected without developing symptoms, and could then silently transmit the virus — especially if they come in close contact with others or stop wearing masks.

If vaccinated people are silent spreaders of the virus, they may keep it circulating in their communities, putting unvaccinated people at risk.

“A lot of people are thinking that once they get vaccinated, they’re not going to have to wear masks anymore,” said Michal Tal, an immunologist at Stanford University. “It’s really going to be critical for them to know if they have to keep wearing masks, because they could still be contagious.”

In most respiratory infections, including the new coronavirus, the nose is the main port of entry. The virus rapidly multiplies there, jolting the immune system to produce a type of antibodies that are specific to mucosa, the moist tissue lining the nose, mouth, lungs and stomach. If the same person is exposed to the virus a second time, those antibodies, as well as immune cells that remember the virus, rapidly shut down the virus in the nose before it gets a chance to take hold elsewhere in the body.

...a little bit of important continuation...

The coronavirus vaccines, in contrast, are injected deep into the muscles and stimulate the immune system to produce antibodies. This appears to be enough protection to keep the vaccinated person from getting ill.

Some of those antibodies will circulate in the blood to the nasal mucosa and stand guard there, but it’s not clear how much of the antibody pool can be mobilized, or how quickly. If the answer is not much, then viruses could bloom in the nose — and be sneezed or breathed out to infect others.

“It’s a race: It depends whether the virus can replicate faster, or the immune system can control it faster,” said Marion Pepper, an immunologist at the University of Washington in Seattle. “It’s a really important question.”

This is why mucosal vaccines, like the nasal spray FluMist or the oral polio vaccine, are better than intramuscular injections at fending off respiratory viruses, experts said.

The next generation of coronavirus vaccines may elicit immunity in the nose and the rest of the respiratory tract, where it’s most needed. Or people could get an intramuscular injection followed by a mucosal boost that produces protective antibodies in the nose and throat.

The coronavirus vaccines have proved to be powerful shields against severe illness, but that is no guarantee of their efficacy in the nose. The lungs — the site of severe symptoms — are much more accessible to the circulating antibodies than the nose or throat, making them easier to safeguard.

... Dr. Bhattacharya said he was encouraged by recent work showing that people who received an intramuscular flu vaccine had abundant antibodies in the nose. And a study of Covid-19 patients found that antibody levels in saliva and blood were closely matched — suggesting that a strong immune response in the blood would also protect mucosal tissues.

So your body is immune, but your NOSE will be a virus factory and you will spew virions all over the world AFTER you get vaccinated. Therefore you will have to wear a mask the rest of your life. Biden should change his "100 Days to Wear a Mask" to "Wear a Mask for All Eternity."

Here’s why you can shove all of that stuff up your home six....

[AFB-XYZ]

Amen to that, #2.

So how was being vaccinated any different than being an unsymptomatic carrier?

[Edward Teach]

"That leaves open the possibility that some vaccinated people get infected without developing symptoms"

Epidemiology FAIL! Immune means you CANNOT become infected, AT ALL! Your immune system will produce antibodies IMMEDIATELY when a targeted invader appears, at a rate hundreds of times faster than the invader can replicate itself. It will NOT be able to gain even the tiniest of toeholds in a system that has been IMMUNIZED.

[Responsibility2nd]

Let’s say I have had COVID-19, and let’s say that I have subsequently been vaccinated against COVID-19, will I still need to wear a mask?

Don’t answer that. You know and I know health officials could not possibly dream of any situation where masks are not required.

[mask] == [niqab]

[TheRake]

FUNYT

[Hulka]

So, for ever and ever we must wear a mask?

Don’t think so.

[RoadGumby]

No.

[Zeddicus]

You vill vare zee muzzle! No exception!

[Diogenesis]

IF the slave masks of the DNC collected viruses
and the DNC/Xi/FauXi/Soros WANTED to not murder people
... why were they never collected and destroyed??

“That leaves open the possibility that some vaccinated people get infected without developing symptoms, and could then silently transmit the virus —”

The media is being told to repeat the asymptomatic bogey man.

There is no empirical science or study show the majority of asymptomatic people being “silent spreaders”.

Why? Viral load.

If the asymptomatic person had a transmissible level of a viral load they would not be asymptomatic - they would not be internally succeeding against the virus, as they demonstrably are, they would be symptomatic not asymptomatic. Like nearly all Covid-19 children, asymptomatic people do not typically have high viral loads and do not expel virulent doses of the virus. Like most all children they are neither ill nor spreaders of the bug.

The asymptomatic “spreader” is part guessing and part social behavior controlling bogey man.

[ProudDeplorable]

So Masks indefinitely - What a joke!!

[Golden Eagle]

If vaccinated people are silent spreaders of the virus, they may keep it circulating it

Insane. If vaccinated people are spreading the virus, it clearly means the vaccine doesn’t work!

At least it doesn’t work at stopping the disease, but who knows what all else they are programming into it.

[Socon-Econ]

Has the nature of viruses changed? The proponents of this absurd theory have not identified any other VIRUS that has been shown to be an ongoing asymptomatic silent spreader. This not like the Typhoid Mary bacillus.

[Adder]

What a complete load of crap.

They already see that there will be an issue with the vaccinated and non vaccinated comingling in an amorphous mass that they can’t visually see or check.

Correct me if I am wrong, but if you have the chicken pox vaccine, you don’t become a spreader of chicken pox.

Sounds more like these snowflakes don’t want people daring to live life again.

[Mr Rogers]

I’ve seen no evidence asymptomatic people transmit the disease. Even the WHO estimated it at less than 1% of all transmissions. So....what part of FU does Biden understand?

[wastedyears]

GFY, NY Slimes.

[Vendome]

The masks carry pathogens from days of use without changing
