COVID vaccines slightly affect menstrual cycles but do not affect menses

A new peer-reviewed paper showed that COVID-19 vaccines slightly and temporarily increased the length of menstrual cycles. The research also showed that the vaccine did not change the number of days of menses. The effects are so minor as to not warrant concerns about these vaccines.

This brief post is just going to lay out the data from the article and try to show that if you are a woman considering the vaccine, this shouldn’t be a concern.

COVID-19 vaccine facts and myths – UPDATED info about the new vaccines

COVID-19 vaccine facts

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.

FDA rejects ICAN petition to revoke of EUAs issued for COVID vaccines

ICAN COVID-19 vaccines

This article about the FDA’s actions on a petition from ICAN to revoke EUAs for COVID-19 vaccines was written by Viridiana Ordonez. Ms. Ordonez has contributed other articles to this website and is aJ.D. candidate at the University of California, Hastings College of Law.

Del Bigtree‘s Informed Consent Action Network (ICAN) submitted a Citizen Petition to the Food and Drug Administration (FDA) on September 27, 2021. In its petition, ICAN requested that the FDA revoke the Emergency Use Authorization (EUA) granted to ModernaTX, Inc. (Moderna) and JNJ Jansen Biotech, Inc. (Janssen) for their COVID-19 vaccines.

ICAN argued that because the FDA has now approved Comirnaty – the COVID-19 vaccine created by Pfizer-BioNTech – the requirements for issuance of the EUA for the other vaccines are no longer met.

The FDA replied to the petition on October 20, 2021, and rejected the request, explaining that ICAN’s petition did not contain facts demonstrating any reasonable grounds for its request. This post summarizes FDA’s response.

COVID-19 vaccine mortality risk is lower than in an unvaccinated group

COVID vaccine mortality

The COVID-19 vaccine mortality risk has been a subject of a lot of myths and misinformation ever since the vaccines were released. Too much of the false information relies upon dumpster diving into the Vaccine Adverse Event Reporting System (VAERS) rather than good science that might show causality.

The CDC published a study in the peer-reviewed Morbidity and Mortality Weekly Report on 22 October 2021 which examined the risk of non-COVID mortality in a COVID-19 vaccine group compared to an unvaccinated group. So that I don’t bury the lede, the risk of death from non-COVID causes was much higher in the unvaccinated group compared to the vaccinated one.

Let’s look at the details.

COVID-19 vaccine boosters FAQs – what you should know

COVID-19 vaccine boosters

Following the advice of the Vaccine and Related Products Advisory Committee (VRBPAC), the FDA announced that COVID-19 vaccine boosters can be given to those individuals who received the Moderna and JNJ vaccines. This follows a previous announcement about the Pfizer vaccine booster shots. The FDA also stated that all eligible individuals could mix and match vaccines for their booster dose.

There is a lot of information about these boosters out there, so I thought I would take a moment to try to provide some facts and clarity about what the recommendations are about these COVID-19 vaccine boosters. Also, this is related to a US FDA set of decisions and recommendations from the CDC, so this article is going to only apply to the USA. However, don’t be surprised if the EU and other regulatory agencies across the world do the same thing.

No graphene oxide in COVID vaccines – debunking another anti-vax myth

graphene oxide COVID-19 vaccines

While reading anti-vax propaganda, I found a claim that there is graphene oxide in COVID-19 vaccines. I know, what the everlasting F*** is graphene oxide and why is it in our COVID-19 vaccines?

Well, I decided to dig into this myth and figure out what this nonsense is all about. It’s been around for a few months, but it seems to be rearing its zombie meme head again in several places.

But you and I both know that if it comes from the mouth of an anti-vaxxer, we can be assured that it’s far from factual or scientific.

Nicki Minaj, COVID-19 vaccines don’t cause swollen testicles or impotence

people holding small clear glass bottles

I don’t know what it is about vaccines and fear of infertility, but now rapper Nicki Minaj has stepped into the COVID-19 vaccine “discussion.” And like every claim that, in some magical way, vaccines have an effect on fertility, she’s wrong.

Worse yet, Nicki Minaj knows as much about vaccines as my cat, yet she gets to use her platform on social media to spread her misinformation. That’s the battle for the hearts and minds of people in these vaccines discussions is so difficult – maybe 10,000 people will read this article in which I debunk the “COVID-19 vaccine causes infertility” myth for the 10th time. But millions will see her social media posts.

So, here I go again, I’m going to tell you again that vaccines, specifically the ones for COVID-19, are not going to cause infertility in men or women. Sigh. And the thought that I have to write a debunking of something from Nicki Minaj is surreal.

COVID-19 vaccines and blood clots – a review of current science

COVID-19 vaccines blood clots

There have been extremely rare reports about blood clots being related to the JNJ and AstraZeneca COVID vaccines. Although science does not why this happens, researchers continue to explore why these COVID-19 vaccines might be linked to blood clots (thrombus).

A new review of the current research clears up some of the mystery, but, unfortunately, opens up some new questions. This article will examine the science, at least as far as we know, behind these blood clots and the two COVID-19 vaccines.

Experimental COVID vaccines? Another anti-vaxxer trope to be debunked


And here we go with another one of those silly anti-vaxxers tropes – the COVID-19 vaccines are experimental, and the government/Big Pharma/Bill Gates are conspiring to test the vaccine on innocent people. Nothing could be further from the truth.

The claim that the COVID-19 vaccines are experimental probably arises from the fact that most of them received anEmergency Use Authorization (EUA) in the USA and other countries. The anti-vaxxers what to use the EUA to make a strawman argument that EUA is equivalent to “a risky, experimental drug that will cause great harm to you.”

But if these anti-vaccine activists spent just a little bit of time to understand the high-quality science behind these vaccines and the Emergency Use Authorizations, they might move on to some other topic. But in case someone finds this article among all of the nonsense on the internet, looking to find out if COVID-19 vaccines are, in fact, experimental, let’s debunk that with actual facts.

America’s Frontline Doctors anti-vaccine affidavit – expert analysis

America's Frontline doctors affidavit

This article, about America’s Frontline Doctors anonymous anti-vaccine affidavit, was written by Kelsey S Hollenback, a Ph.D. student in Systems & Information Engineering at the Center for Risk Management of Engineering Systems, Department of Engineering Systems and Environment, School of Engineering and Applied Sciences, University of Virginia.

On reviewing America’s Frontline Doctors anonymous affidavit, part of a recent lawsuit over the COVID-19 vaccines, my first and most important takeaway is that, while Jane Doe apparently wishes to assert that she has discovered excess mortality associated with COVID-19 vaccines, what she describes in her affidavit bears absolutely no resemblance to how to conduct an actual such analysis.  Not even a little bit.

My second takeaway, which almost doesn’t matter given the first, is that, insofar as it’s possible to determine the methodology she used from the extremely limited description provided, that methodology is…flawed. 

Flawed in what ways? It counted more deaths associated with a COVID-19 vaccine than there are total deaths recorded in VAERS. It doesn’t account for differences between the CMS patient population and the general population. Depending on what criteria Jane Doe used to query the CMS claims database, she may have pulled patients receiving any vaccine, not just the COVID-19 vaccine; she may have pulled only patients receiving Moderna, or only Pfizer, or only Johnson & Johnson; she may have failed to pull patients receiving a no-cost or government-provided vaccine; and/or she may have oversampled patients at higher risk generally for all-cause mortality.

My third and final takeaway is that, while America’s Frontline Doctors affidavit does not in any way describe either a valid method for identifying excess mortality associated with the COVID-19 vaccine, doesn’t do anything at all to establish causality, and certainly doesn’t expose any cover-up, it does possibly reveal a serious HIPAA violation.
