From the Wallstreet Journal. Why Covid 19 shots don't last a lifetime.
Some Vaccines Last a Lifetime. Here’s Why Covid-19 Shots Don’t.
Researchers have calculated a key number—the threshold of protection—for other vaccines. Covid-19’s is still a mystery.
Why don’t Covid-19 vaccinations last longer?
Measles shots are good for life, chickenpox immunizations protect for 10 to 20 years, and tetanus jabs last a decade or more. But U.S. officials are weighing whether to authorize Covid-19 boosters for vaccinated adults as soon as six months after the initial inoculation.
The goal of a vaccine is to provide the protection afforded by natural infection, but without the risk of serious illness or death.
“A really good vaccine makes it so someone does not get infected even if they are exposed to the virus,” said Rustom Antia, a biology professor at Emory University who studies immune responses. “But not all vaccines are ideal.”
The three tiers of defense, he said, include full protection against infection and transmission; protection against serious illness and transmission; or protection against serious illness only.
The effectiveness depends on the magnitude of the immune response a vaccine induces, how fast the resulting antibodies decay, whether the virus or bacteria tend to mutate, and the location of the infection.
The threshold of protection is the level of immunity that’s sufficient to keep from getting sick. For every bug, it’s different, and even how it’s determined varies.
“Basically, it’s levels of antibodies or neutralizing antibodies per milliliter of blood,” said Mark Slifka, a professor at Oregon Health & Science University.
(T-cells also contribute to protection, but antibodies are easier to measure.)
A threshold 0.01 international units per milliliter was confirmed for tetanus in 1942 when a pair of German researchers intentionally exposed themselves to the toxin to test the findings of previous animal studies.
“One of them gave himself two lethal doses of tetanus in his thigh, and monitored how well it went,” Dr. Slifka said. “His co-author did three lethal doses.”
Neither got sick.
A threshold for measles was pinned down in 1985 after a college dorm was exposed to the disease shortly after a blood drive. Researchers checked antibody concentrations in the students’ blood donations and identified 0.02 international units per milliliter as the level needed to prevent infection.
With these diseases, the magnitudes of response to the vaccines combined with the antibodies’ rates of decay produce durable immune responses: Measles antibodies decay slowly. Tetanus antibodies decay more quickly, but the vaccine causes the body to produce far more than it needs, offsetting the decline.
“We’re fortunate with tetanus, diphtheria, measles and vaccinia,” Dr. Slifka said. “We have identified what the threshold of protection is. You track antibody decline over time, and if you know the threshold of protection, you can calculate durability of protection. With Covid, we don’t know.”
Historically, the most effective vaccines have used replicating viruses, which essentially elicit lifelong immunity.
Measles and chickenpox vaccines use replicating viruses.
Non-replicating vaccines and protein-based vaccines (such as the one for tetanus) don’t last as long, but their effectiveness can be enhanced with the addition of an adjuvant—a substance that enhances the magnitude of the response.
Tetanus and hepatitis A vaccines use an adjuvant.

T he Johnson & Johnson and AstraZeneca Covid-19 vaccines use non-replicating adenovirus and don’t contain an adjuvant. The Pfizer and Moderna messenger RNA Covid-19 vaccines, which work differently, don’t contain any virus at all.
Complicating things further, viruses and bacteria that mutate to escape the body’s immune response are harder to control.
Measles, mumps, rubella and chickenpox hardly mutate at all, but at least eight variants of SARS-CoV-2, the virus that causes Covid-19, have been found, according to the British Medical Journal.
“It does make it more complicated for the vaccine to work,” Dr. Slifka said. “You’re chasing multiple targets over time. Flu also mutates. With flu, we’ve adjusted by making a new flu vaccine each year that as closely as possible matches the new strain of flu.”

F lu vaccines can offer protection for at least six months.
Setting aside the complexities of crafting an effective vaccine to combat a shape-shifting virus, some hope has revolved around the possibility of defeating Covid-19 by achieving herd immunity, but, according to Dr. Antia, the way coronaviruses infect the body makes that challenging.
“Vaccines are very unlikely to lead to long-lasting herd immunity for many respiratory infections,” Dr. Antia said. “The herd immunity only lasts for a modest period of time. It depends on how fast the virus changes. It depends on how fast the immunity wanes.”
Part of the problem is that coronaviruses replicate in both the upper and lower respiratory tracts.
“We have good circulation in our lungs and body, but not on the surfaces of our nostrils,” Dr. Slifka said. “We can block severe disease because there are antibodies in the lower respiratory tract.”
But the risk of low-level infections in the upper respiratory tract can persist.
Moving forward, Covid-19 vaccines will be updated to combat variants of the virus, and according to researchers at Imperial College London, the next generation of vaccines might also focus on enhancing immunity in the moist surfaces of the nose and lungs.
In the meantime, avoiding the slippery virus might require another shot.

- HERE IS A GOOD QUESTION?
- -----------------------------------------
- WHICH COUNTRIES ARE BUYING BRAZILIAN BEEF AND/OR BRAZILIAN SOY PRODUCTS AND CONTRIBUTING TO THE DESTRUCTION OF THE BRAZILIAN AMAZON RAIN FOREST?
- "Harness agriculture: efforts will get underway to transform our agricultural systems with a view to curtailing emissions and improving the capture and storage of carbon in the ground.
- Adapt to climate change: a new National Plan for Adaptation to Climate Change (PNACC) will be unveiled to provide French citizens with more effective protection against extreme weather events and to build resilience among the main economic sectors so that they can better withstand climate change.
- Stop importing products that contribute to deforestation: imports of products that are bringing about the destruction of the world's three major tropical rainforests (Amazonia, South-East Asia and Congo Basin) will be swiftly brought to a halt."

GOOD IDEAS!
HERE ARE A FEW MORE GOOD IDEAS!!
INTERNATIONAL LABORATORIES CAN NOW RENDER DANGEROUS CORONA VIRUS SUCH AS COVID-19...HARMLESS! THE COMMON COLD IS ALSO A CORONA VIRUS AND IT IS A MONEY MAKER FOR PHARMACEUTICAL COMPANIES BECAUSE IT IS NON-LETHAL.
BLOCKING THE SYMPTOMS OF THE COMMON COLD IS GREAT FOR BUSINESS BUT WHEN IT COMES TO CURING THE COMMON COLD, THAT IS NOT SO GREAT FOR THE PRODUCERS OF ASPIRIN AND TYLENOL AND ADVIL...ETC. BIG PHARMA IS FUNNELLING IN BILLIONS BY SIMPLY BLOCKING THE SYMPTOMS AND ALLOWING THE VIRUS TO SURVIVE.
1. BLOCKING THE SYMPTOMS OF THE COMMON COLD VIRUS IS A MULTI MILLION DOLLAR INDUSTRY. THE COLD VIRUS HAS A ROUND CORONA SHAPE AND IS PART OF THE CORONA FAMILY AND FOR DECADES THE COMMON COLD WITH IT'S MORE SERIOUS COUSIN, THE FLU, HAVE HELPED TO CREATE AN EXTREMELY LUCRATIVE BUSINESS FOR THE PHARMACEUTICAL COMPANIES.
2. AS THEY ARE FOR THE MOST PART NON LETHAL, THE COLD AND FLU VIRUS MAY OR MAY NOT BE PROTECTED FROM COMPLETE DESTRUCTION BY THE SAME COMPANIES NOW PRODUCING VACCINES FOR THEIR MORE LETHAL COUSIN, THE COVID-19 VIRUS.
3.. A FEW IMPORTANT LABORATORIES AND THEIR GOVERNMENT SPONSORS ARE THREATENING THE ECONOMIC STABILITY OF MANY "SYMPTOM" BLOCKING COMPANIES BY CREATING AN HONEST AND ABSOLUTE CURE FOR THE COMMON COLD ALONG WITH ALL OF IT'S CORONA COUSINS, INCLUDING COVID 19.
4. TODAY, LABORATORY RESEARCHERS ARE USING CRISPR-CAS 9 TO TRANSFORM DEADLY VIRUS INTO BENIGN LIFE SAVING VIRUS. NEW VACCINES AND GENETIC MODIFICATION METHODS ARE NOW EFFECTIVELY PROVIDING PROTECTION AGAINST COVID-19 AND THE FLU AND THE COLD VIRUS,
PROTECTING AGAINST "CORONA" VIRUSES.
ALONG WITH VACCINES, LABORATORY RESEARCHERS HAVE DISCOVERED WAYS AND METHODS SUCH AS "CRISPER-CAS 9" AND "TIPS" TO ALTER THE GENES OF DANGEROUS VIRUS IN ORDER TO RENDER THE CORONA VIRUS MUTE. OF COURSE THESE DISCOVERIES WILL FINANCIALLY ENDANGER COMPANIES PRODUCING SYMPTOM BLOCKING AND CASH MAKING PRODUCTS LIKE: ASPIRIN, TYLENOL ADVIL...ETC.
CONCLUSION: Scientific breakthroughs are creating a future without deadly diseases.

THE BRAZILIAN AMAZON IS ON FIRE!!
Tipping point?
| Fri, Aug 20, 4:08 PM (3 days ago) | |||

Hi Nelson, It’s beginning. As people around the world struggle with the impacts of a heating climate, fire season is now underway in the Amazon. As you read this, landgrabbers are intentionally setting fire to the Amazon rainforest to clear land for cattle ranching and industrial agriculture. We’re being warned that this year’s fires in the Amazon could be the worst ever, due to a devastating combination: a historic drought, record high levels of deforestation, and the anti-environmental agenda of Brazil’s far-right President Jair Bolsonaro. [1] The situation is critical. Last month we learned that vast areas of the Amazon are already emitting more carbon than they absorb, as fires and deforestation ravage the landscape and the remaining rainforest dries out. [2] This is the tipping point scientists have warned us about — the moment is here. But there is something we can do. Take action now. International pressure from Brazil’s trading partners is critical at this moment — and has already caused the Bolsonaro government to delay the worst of its destructive plans. [3] And yet as other governments and companies around the world speak out, our current Liberal government has remained silent — and is even planning to reward Bolsonaro with a lucrative trade deal. This is unacceptable. But together we have the power to hold our government to account. More than 50,000 Canadians have already called on the current Liberal government to halt the planned Canada-Mercosur free trade deal and speak out against Bolsonaro’s destruction of the Amazon. Together we can and must pressure government to stop prioritizing corporate interests and prevent an ecological catastrophe. That starts with calling on the acting Liberal government to make this commitment during this important election period. Because losing the Amazon is not an option. Indigenous peoples of Brazil are sounding the alarm on this crisis [4] and have issued an international call for solidarity. It’s time for us to respond. Thank you for taking action.

Mistakes of government.
DEAR PRESIDENT BIDEN:
You mentioned on television how the U.S. government spent billions arming the Afghanistan military. Why the U.S. government did this is no longer important as Taliban insurgents took over from the U.S. sponsored Afghani military and now have control of the country.
In my not so humble opinion, U.S. funds may have been better spent improving lives inside impoverished rural areas of Afghanistan.
Afghanistan could use thousands of new: hospitals, schools, small businesses, community gardens and parks.
If providing guns to the Afghanistan military was so important, the U.S. should also have given small hand guns to every woman in Afghanistan with instructions on how to use them if attacked or abused. I believe it would have been a lot cheaper for the U.S. government and exceedingly more empowering as well as liberating for the women of Afghanistan.
These are only my opinions but political mistakes are often repeated in every government and maybe these ideas will help future politicians create alternatives to war, murder, bloodshed and human rights violations.
N.J.R.
P.S. There is something else I find curious. If governments and companies find it convenient to place small GPS chips in every telephone and computer identifying the location of the user in North America; why not hide these chips in all the guns delivered outside of North America? And why not make our guns look exactly like those made in China or Russia? Something to think about...right?

========================================== The 2021 campaign has officially started, Joseph – here’s how you can help today! Justin Trudeau and our Liberal teams across the country need your help – knocking on doors, making phone calls, and supporting our movement in any way you’re able to – and there’s never been a more important time to get involved! Just yesterday, Erin O’Toole’s Conservatives launched their 2021 platform, with plans to end COVID support programs, weaken Canada’s climate plan, scrap $10/day child care, make assault weapons legal again, and put Canadians at risk by rolling back mandatory vaccination. While Conservatives want to take us back, we’re for moving Canada forward – for everyone. That’s why what you do today is crucial in helping ensure our teams have the funds, volunteers, and support they need to power them all the way through to Election Day on September 20th! Here are some quick actions you can take right now: |
This movement is built on grassroots support from thousands of Liberals across the country, Joseph. That’s why we’re counting on you to get involved! Thank you for standing with us. |
