CDC’s Vaccine Adverse Event Reporting System (VAERS)

Here’s the CDC’s database for adverse reactions to vaccines, including the COVID-19 vaccines. The data is submitted voluntarily. Anyone – healthcare providers, the public – can submit a report.

Vaccine Adverse Event Reporting System (VAERS)

The Vaccine Adverse Event Reporting System (VAERS) database contains information on unverified reports of adverse events (illnesses, health problems and/or symptoms) following immunization with US-licensed vaccines. Reports are accepted from anyone and can be submitted electronically at

Results are updated on Fridays, so this data is several days old. It’s not a complete list by any means and it may not be very accurate but it does provide some data. I don’t know how many people were vaccinated then but this shows 353 total adverse events. VAERS is known to underreport.

These are the top adverse reactions (to all manufacturers’ vaccines combined: Pfizer, Moderna, etc.), in alphabetical order. (Top reaction is headache.):

Joni Mitchell – Urge For Going

Urge For Going
Written, composed, and performed by Canadian singer-songwriter Joni Mitchell.

This is a live version recorded in Ontario on 24 October 1966. She was 22 years old here, an emerging artist. She recorded her first album in 1968. (I get a kick out of the other musicians watching her.)

“Urge For Going” was originally recorded by Tom Rush in 1967, Mitchell’s own version (recorded for Blue but left off the album at the last minute in favor of newer songs) was not released until 1972, as the B-side of the “You Turn Me On, I’m a Radio” single. It was first available on a Joni Mitchell album as part of her 1996 greatest hits compilation.

I awoke today and found the frost perched on the town
It hovered in a frozen sky then it gobbled summer down
When the sun turns traitor cold
And all the trees stand shivering in a naked row.

I get the urge for going but I never seem to go
I get the urge for going
When the meadow grass is turning brown and
Summertime is falling down and winter is closing in.

I had a man in summertime, with summer-colored skin
And not another girl in town my darling’s heart could win
But when the leaves fell trembling down and
Bully winds did rub their faces in the snow.

He got the urge for going and I had to let him go
He got the urge for going
When the meadow grass was turning brown and
Summertime was falling down and winter closing in.

Now the warriors of winter they gave a cold triumphant shout
And all that stays is dying and all that lives, is gettin’ out
See the geese in chevron flight
Flapping and racing on before the snow.

They got the urge for going
And they got the wings so they can go
They get the urge for going
When the meadow grass is turning brown
Summertime is falling down and winter is closing in.

So I’ll ply the fire with kindling
pull the blankets to my chin
I’ll lock the vagrant winter out and
fold my wandering in
I’d like to call back summertime and
Have her stay for just another month or so.

But she’s got the urge for going
So I guess she’ll have to go
She gets the urge for going
When the meadow grass is turning brown
All her empire’s falling down and winter’s closing in.
And I get the urge for going
When the meadow grass is turning brown
And summertime is falling down.

The Back. How To Prevent Injury. How To Heal It.

Lots of snow. Lots of shoveling. A good time to revisit Dr. McGill’s back post (reposted below).

If you read no further, the core lesson, for both prevention and healing is … keep the back straight. Walking, sitting, working, exercising … endeavor to keep the back and neck in a straight line. If you have to twist or bend, try not to do it with a load or at a great angle (shoveling snow!). Repetition is also not good. McGill says the muscles of the back and abdomen are meant to stabilize, to prevent movement.


In the very beginning of this video, Dr. McGill* is using a simulator to create a disc herniation by merely flexing and bending a spine repeatedly, in a movement that resembles a sit-up. The rest of the video shows how to perform his 3 basic exercises for strengthening the abdominal muscles without injuring the back (modified curl-up, bird dog, side plank).

Here he is discussing myths about exercise. Did you know that sucking in your stomach is harmful? It can cause the spine to buckle (a sideways deflection).

He says that a flexible back or a strong back are not protective of back injury. In fact, they are associated with more injury. The muscles of the back are meant to stabilize, to prevent movement. This is true for abdominal muscles and others of the core or torso. However, since back and stomach muscles are in constant use, they need to be maintained to provide endurance.

Here’s another video showing McGill’s “Big 3” exercises for stabilizing the back:

Bird Dog
Modified Curl-up
Side Plank

* Dr. Stuart McGill is a professor emeritus at the University of Waterloo where he taught for 32 years. His research involved how the back functions, how it becomes injured, how to prevent injury, how to rehabilitate an injured back, and how to enhance athletic performance. His clients include professional athletes. He currently serves on the editorial boards for the journals Clinical Biomechanics, Applied Biomechanics, and Spine, and is the author of several books.

Most people will not get through life without some element of back pain impinging on their activity. -Dr. McGill

Vitamin C Supplements Reduce Endurance, Fatigue Muscles Sooner

1000 milligrams, a gram, of vitamin C is a lot. The RDA is 75 mg (women), 90 mg (men). An orange has about 60 mg. Studies are finding that vitamin C can inhibit the body’s natural ability to adapt to exercise, blunting the body’s ability to produce its own powerful antioxidants.

Below is an excerpt from a post from my old blog, from February 2009. I’m revisiting it because I just read that a high-end supplement for athletes removed vitamin C from some of their formulations, citing this study and others.

Oral Administration Of Vitamin C Decreases Muscle Mitochondrial Biogenesis And Hampers Training-Induced Adaptations In Endurance Performance, American Journal of Clinical Nutrition, January 2008

Researchers trained a group of humans and a group of rats. Some received vitamin C.


1. Vitamin C reduced endurance.

Training increased the maximal running time in rats [by 186.7%]. However, this increase was prevented by daily supplementation with vitamin C. In the supplemented animals, the running time increased only 26.5%.

2. Vitamin C reduced the number of mitochondria (energy-producing cells) that bodies make in response to exercise.

The graph below shows the change in level of transcription factors needed for mitochondrial production. Look at the vitamin C group – almost equal to levels in untrained rats.

The number of mitochondria is linked to endurance and fatigue. (See No. 1 above.)

Endurance capacity [time to fatigue] is dependent mainly on the mitochondrial content of skeletal muscle.

3. Vitamin C reduced the amount of endogenous (made by our body) antioxidants.

Two antioxidant enzymes, superoxide dismutase and glutathione peroxidase (GP), were found in lower levels in those taking vitamin C. Recall that acrylamide in browned and aged foods is metabolized by GP – a good thing. In fact, GP is widely used in cells to prevent damage from oxidation.

The graph below shows the change in levels of these two antioxidants. Again, the vitamin C group was almost equal to levels in untrained rats.

Exercise generates oxidized compounds. It was thought that by consuming more antioxidants, e.g. vitamin C, we could protect our cells against these oxidized compounds (known as reactive oxygen species: ROS).

We’re finding that ROS aren’t altogether bad. The body uses them as signals. Previous posts discussed this, e.g. the case of too much selenium reducing ROS leading to insulin resistance and weight gain.

In this case, ROS signals the body to make more mitochondria, and more in-house antioxidants. It probably does other things, but this study measured just those variables.

Thus, the common practice of taking vitamin C supplements during training (for both health-related and performance-related physical fitness) should be seriously questioned.

The supplement I mentioned at the top of this post, the one that removed vitamin C from formulations, was First Endurance. Here’s an article they posted which pulls together other studies supporting this hypothesis.

Update: More Studies Show Vitamin C & E May Reduce Endurance Capacity & Performance, First Endurance, 28 March 2017

This is not just about athletes. It applies to anyone who exercises to keep fit.

The Link Between Eggs And Diabetes Is Not New

I was going to tack this on to my last post but decided it deserved its own. It’s not a new study, but it shows that the association is not new.

Egg Consumption And The Risk Of Diabetes In Adults, Jiangsu, China, Applied Nutritional Investigation, February 2011

After the adjustment for age, total calorie intake, education, smoking, family history of diabetes, and sedentary activity, egg consumption was significantly and positively associated with diabetes risk, particularly in women.

In addition, plasma triglyceride and total cholesterol levels were significantly higher in women who consumed ≥2 eggs/wk than those who consumed eggs less often.

“People Who Regularly Consumed One Or More Eggs Per Day Increased Their Risk Of Diabetes By 60%”

Higher Egg Consumption Associated With Increased Risk Of Diabetes In Chinese Adults – China Health And Nutrition Survey, British Journal of Nutrition, 8 October 2020 Online

Press release:
Go (Over) Easy On The Eggs: ‘Egg-cess’ Consumption Linked To Diabetes, Eurekalert, 14 November 2020

People who regularly consumed one or more eggs per day increased their risk of diabetes by 60%.

This is the kind of result you see when the study is conducted outside of the US, away from the influence of the American Egg Board and the USDA.
