This pandemic just doesn’t give us much good news — research from the UK indicates that COVID-19 vaccine booster effectiveness may wane significantly at the 10-week mark post-vaccination. This may allow the Omicron variant to spread much further than originally hoped.
Before I explain the research, I want to make a few things very clear. First, this doesn’t mean the vaccine is ineffective, it is just that the immunity appears to wane more quickly than other vaccines. Second, this doesn’t mean that the vaccines are worthless — hospitalization and, more importantly, death rates are much lower in the vaccinated group. And finally, this is how science works — we accumulate data and then, after reviewing the data, change recommendations.
Let’s take a look at this new research and determine what it may mean for future vaccination efforts. Continue reading “COVID vaccine booster effectiveness may wane quickly against Omicron”
There are so many myths about the COVID-19 vaccine, I wanted to post some facts about the new vaccines which we can use for debunking purposes. I used to think that the HPV vaccine brought the most hatred and misinformation from the anti-vaccine world, but it’s clear that the new COVID-19 vaccines are their new targets.
This article will only focus on the five vaccines that I believe will eventually receive FDA or European Medicines Agency (EMA) approval – Pfizer, Moderna, AstraZeneca, Johnson & Johnson (JNJ Janssen), and Novavax vaccines. I remain unconvinced that any vaccine made in China or the Russian Sputnik V vaccine will ever get approved by countries with robust drug regulatory agencies. However, if they are, I will certainly add them to a future iteration of this list.
I’m going to make this in a basic chart form for ease of use. I will link to supporting evidence wherever relevant. Continue reading “COVID-19 vaccine facts and myths – UPDATED info about the new vaccines”
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. Continue reading “COVID-19 vaccine shedding – another anti-vaccine myth to scare people”
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. Continue reading “JNJ COVID-19 vaccine and blood clots – still safe and effective”
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. Continue reading “Adenovirus vaccines for COVID-19 – scientific facts vs anti-vax nonsense”
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. Continue reading “COVID-19 vaccine choices – which one should you get?”
On 26 February 2020, the Johnson and Johnson (JNJ) COVID-19 vaccine underwent an FDA expert review, similar to the ones for the Pfizer and Moderna COVID-19 vaccines. The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted unanimously in favor of the third vaccine in the USA to prevent COVID-19. On 27 February 2020, the USFDA gave clearance for an Emergency Use Authorization (EUA).
VRBPAC agreed that the vaccine was very effective, especially in preventing death and serious COVID-19 disease. They also found no serious safety signals, with the incidence serious adverse events were no higher compared to the placebo group or what would be expected in the general population.
The EUA approved the vaccine for use in adults 18 and older. Before JNJ can ship the vaccine, the CDC’s Advisory Committee on Immunization Practices (ACIP) will meet tomorrow to make recommendations on who can receive this vaccine. Continue reading “JNJ COVID-19 vaccine receives FDA emergency use authorization – great news”
On 26 February 2020, the Johnson and Johnson (JNJ) COVID-19 vaccine underwent an FDA expert review, similar to the ones for the Pfizer and Moderna COVID-19 vaccines. The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted unanimously in favor of the third vaccine in the USA to prevent COVID-19. This vote by the vaccine experts is the last step in advance of FDA clearance for an Emergency Use Authorization (EUA).
This article will review the key points about the Johnson and Johnson COVID-19 vaccine’s safety, effectiveness, ingredients, and other critical information. This scientific information should answer a lot of questions about the vaccine that will inevitably arise over the next few weeks.
This will be different than my myth debunking article (which will be constantly updated as the anti-vaxxers get going with their lies and disinformation), as this article will try to make sure that everyone is on the same page with what this vaccine is.

One of the enduring myths about vaccines is that they’re rushed to market, which has continued with COVID-19 vaccines. This myth doesn’t arise because the anti-vaxxers have some “gotcha” information about these vaccines, it’s because they are intent on pushing fear, uncertainty, and doubt.
If you read my articles since March about the development of this vaccine, I was very troubled about the speed of development. Most vaccines take 5-10 years to develop, mostly because we want a better handle on the expected effectiveness and to uncover any potential (and extremely rare) serious adverse events.
But were the COVID-19 vaccine rushed? Not really. Basically, two massive resources – money and brainpower – were thrown at developing a vaccine so that we could stop the inexorable march of the pandemic. The best scientists in the world collaborated with the best pharmaceutical companies with the backing of the richest countries to develop and manufacture safe and effective vaccines.
It wasn’t a magical process where scientists pulled ideas out of thin air to make these vaccines using dangerous technologies. They didn’t.
We know how to train the adaptive immune system to prevent pathogenic diseases with vaccines using all kinds of technologies. Once we were able to isolate the SARS-CoV-2 virus and determine what parts of its structure were the most immunogenic, we knew what to do, it wasn’t a huge mystery at that time.

Lest we forget, vaccines are one of the greatest medical inventions of all time. Without them, we would see cemeteries filled with children who would have died before they were even five years old. In fact, the best evidence we have tells us that vaccines prevented 200 million cases of diseases in the USA alone in the five decades since 1963.
A recent study, published in AIMS Public Health, estimates that around 200 million cases of polio, mumps, rubella, measles, adenovirus, hepatitis A and rabies have been prevented in the U.S. from 1963 through 2015 as a result of widespread vaccination. The study, authored by Leonard Hayflick and S. Jay Olshansky, two leading experts on public health and infectious diseases, also discloses that about 450,000 deaths have been avoided in the U.S during this period, although other studies put that estimate of lives saved at a much higher number.
Dr. Hayflick discovered the human cell strain, WI-38, in 1962 which was critical to the safe manufacturing of vaccines, which became widespread in 1963. According to the article, the vaccines produced from the WI-38 cell line prevented almost 4.5 billion occurrences of the diseases, and stopped them from returning to infect us. Dr. Hayflick developed the foundation that allowed the world to have relative safe and very effective tools to prevent infectious diseases.
Prior to the development of WI-38, anti-virus vaccines were grown in monkey cells, which had some issues that made many question their safety, although most of the concern appeared to be overblown. However, once the WI-38 was available, it became easier to develop and produce vaccines for many viruses.
Drs. Hayflick and Olshansky wanted to see what effect that seminal event had on public health. And the numbers were incredible. Continue reading “Vaccines prevented 200 million cases of disease in the USA from 1963 to 2015”
