COVID herd immunity – vaccine denial may make that impossible

The only way to COVID-19 herd immunity is going to be via vaccines, but people throughout the world, especially in the USA, are refusing the COVID-19 vaccine. The anti-vaccine world is doing everything it can to sow fear, uncertainty, and doubt about these vaccines, despite our efforts to counter the disinformation campaign.

Let’s talk about COVID-19 herd immunity and how vaccines are important. And why we probably can’t hit herd immunity, a terrible consequence of the anti-vaccine rhetoric and lies.

COVID-19 vaccine shedding

COVID-19 vaccine shedding – another anti-vaccine myth to scare people

Here we go again – an expensive, privileged Miami private school has banned teachers who received the COVID-19 vaccine because of “shedding” concerns. Yes, you read that right, the school wrote to teachers that “we cannot allow recently vaccinated people to be near our students until more information is known.”

The school’s co-founder, Leila Centner, claimed that those people who had received the COVID-19 vaccine can somehow shed the spike protein, which in turn can cause menstrual cycle irregularities, miscarriages, and sterility in other women just by being in close proximity to vaccinated people who are shedding something.

Centner wrote, “we cannot allow recently vaccinated people to be near our students until more information is known.” She must get this nonsense from Kelly Brogan, anti-vaccine quack, who seems to have something with Centner and this school

Centner cited debunked claims that the vaccine causes infertility based on “reports have surfaced recently of non-vaccinated people being negatively impacted by interacting with people who have been vaccinated. Let’s be clear that that the scientific consensus about this vaccine is that is very effective and carries few risks.

Simply put, COVID-19 vaccine shedding does not exist, but I will spend a few moments debunking it again.

COVID-19 vaccines herd immunity – ignore anti-vaxxer disinformation

The only way to herd immunity to this pandemic is with COVID-19 vaccines, but still, people are refusing the vaccine, not only in the USA but also throughout the world. But the anti-vaccine world is doing everything it can to sow fear, uncertainty, and doubt about these vaccines.

Herd immunity is a form of indirect protection from infectious diseases that can occur when a sufficient percentage of a population has become immune to an infection, by vaccines or infection, which reduces the risk of infection by members of the community who lack that immunity. Although we don’t have a solid estimate for herd immunity levels for COVID-19, it is estimated to be between 60 and 75%.

Without herd immunity, there are a number of consequences. People who cannot get vaccinated or are immunocompromised will always be at risk of contracting the disease. The virus will continue to be transmitted, which will lead to more dangerous mutations. And there are local outbreaks of COVID-19 across the world that could bring the disease back to the USA and many other countries where we don’t reach herd immunity.

A large group of COVID-19 deniers and anti-vaxxers want to create herd immunity “naturally” instead of using vaccines – that is essentially genocide since so many people will die or suffer long-term consequences.

We need to get the COVID-19 vaccines into as many people as we can so that we can reach herd immunity. Right now, about 25% of Americans may refuse to get the vaccine, and that means we probably cannot reach herd immunity.

mbedThis article is just a list of my articles that can be useful in your arguments with the anti-vaxxers and individuals who are “on-the-fence.”

covid vaccine updates

COVID vaccine updates – large clinical trials will be unnecessary

The questions I keep getting are will we need COVID-19 vaccine updates and how fast could we get them. These are important questions going forward, especially since there are some dangerous variants that seem to be spreading widely.

I think we should look at the model for flu vaccines – each year the antigens are targeted by the vaccine are changed slightly to improve effectiveness. Admittedly, with the flu vaccine, it’s hard to do since the influenza virus can mutate rapidly.

However, regulatory agencies worldwide do not require massive clinical trials for the new formulations, as long as nothing else changes except for the antigens. That’s the model that we will probably require for future COVID-19 vaccine updates in the future.

COVID-19 vaccine blood clots

COVID-19 vaccine blood clots – the FDA and EMA are doing the right thing

If you have been watching the COVID-19 vaccine roll-out, you know that blood clots have become a concern with the vaccines from JNJ (Johnson & Johnson-Janssen) and AstraZeneca. Shockingly, some pro-vaccine types are trying to dismiss these concerns by posting ridiculous memes that try to compare blood clots from these vaccines to ones from birth control pills or smoking.

Setting aside the fact that memes are for the intellectually and scientifically weak, such as anti-vaxxers, these memes are trying to compare apples to bowling balls. Furthermore, ignoring these potential links play right into the hands of the anti-vaccine crowd.

mbedIn my not-so-humble opinion, the US FDA, European Medicines Agency (EMA), and other health agencies across the world have done the right thing by “pausing,” or limiting the use of the vaccines from JNJ and AstraZeneca. Science has been doing the right thing with regards to the COVID-19 vaccine blood clots issue.

JNJ COVID-19 vaccine and blood clots – still safe and effective

Like the earlier story about the AstraZeneca COVID-19 vaccine and blood clots, the JNJ (Johnson and Johnson) vaccine is being examined for a potential link to an extremely rare blood clotting disorder. The US Food and Drug Administration and the CDC have placed a “pause” on the use of the vaccine. They have not banned it. They have not recalled it.

Right at the top, I want to state that the JNJ COVID-19 vaccine is safe and effective by any rational measurement. My daughters and their significant others all received the vaccine over the weekend after I recommended it, despite the blood clots issue.

I want to review what is happening here. I hope that it helps, in some small way, to allay the fears from this issue.

JNJ vaccine clinical trial

JNJ COVID-19 vaccine trial – FDA rejects another ICAN petition

This article about the Informed Consent Action Network’s petition to halt the JNJ COVID-19 vaccine trial was written by Viridiana Ordonez, a J.D. candidate at the University of California, Hastings College of Law

This is a summary of the FDA’s response to a citizen petition dated October 16, 2020, filed on behalf of the petitioner, Del Bigtree’s Informed Consent Action Network (ICAN), relating to the clinical trial of Ad26.COV2S, a Janssen Biotech, Inc. (a subsidiary of Johnson & Johnson, JNJ) COVID-19 vaccine.

Like a previous ICAN petition about COVID-19 vaccine trials, the FDA denied the petition in its entirety. FDA concluded that the vaccine trials were thorough, vaccine safety was carefully tested and monitored, and ICAN’s requests are not well-founded. 

This summary is divided into three parts: (1) ICAN’s specific requests; (2) FDA’s description of the vaccine process and safety; and (3) FDA’s response to six specific requests.

Adenovirus vaccines for COVID-19 – scientific facts vs anti-vax nonsense

The new COVID-19 vaccines from Johnson and Johnson (JNJ) and AstraZeneca utilize an adenovirus-vector to prevent the SARS-CoV-2 virus that causes COVID-19. Of course, this being a new vaccine technology, like the mRNA vaccines used by Pfizer and Moderna, we will be hearing all kinds of false claims about the new adenovirus vaccine.

So, this article will just try to explain what an adenovirus is, how it works in vaccines, and why it is safe. There’s going to be a lot of science here, so I’ll do my best to link you to good articles that explain some of it.

The anti-vaccine squad used an ignorance of basic cell biology to make all kinds of odd claims about the mRNA vaccines such as claiming that it would change the DNA of the vaccine recipient. It can’t.

vaccine profits

Vaccine profits from Big Pharma – let’s take a closer look at this trope

The old myth of the huge Big Pharma vaccine profits – it’s the subject of so many memes, tropes, and outright lies from the anti-vaccine activists. These vaccine deniers, who not only lack knowledge of science but also of basic corporate finance, believe that every Big Pharma CEO relies on vaccines for their next bonus check, which they use to buy their new Ferrari to show off to imaginary vaccine-injured children.

I am not naive – public corporations have an obligation to their shareholders and employees to maximize profits. That’s capitalism, I suppose.

But where this trope goes off the rails is when you realize that vaccine profits would be eclipsed by medical industry profits if Big Pharma simply stopped producing vaccines – mass epidemics would mean that hospitals would be filled with patients, just look at the COVID-19 pandemic. It’s ironic that the anti-vaxxers claim that Big Pharma’s greed gives us vaccines, but if they were truly greedy they’d be out of the vaccine business.

This article is not going to be as much science as I usually do – it’s going to focus on finance and accounting. Yes, I’m a finance and accounting geek as much as I am a science aficionado.

COVID-19 vaccine choices

COVID-19 vaccine choices – which one should you get?

There are now three COVID-19 vaccine choices that have been given clearance under Emergency Use Authorization (EUA) in the USA. The one question I keep getting from friends and strangers is – which of the COVID-19 vaccines should they get?

The three vaccines which have the EUA in the USA, from Pfizer, Moderna, and Johnson & Johnson (JNJ), are very safe and very effective, so my simple answer to the question is succinct – get whichever vaccine is available to you. It probably does not matter in the long run which will be better than the other, they all prevent SARS-CoV-2, the virus that causes COVID-19.

All three of the vaccines, plus additional COVID-19 vaccines from AstraZeneca and Novavax (neither of which have submitted EUAs to the FDA as of this date), will be available in the developed world, that is, the European Union, USA, Japan, Canada, Australia, and New Zealand. Each country will have slightly different combinations of these vaccines available, but this discussion should be germane to anyone asking about which to get.
