Mix and match vaccines

I got my 2nd vaccine dose last night. In the lineup I was asked, “First or second dose.”

“Second.”

“Which Vaccine did you get for your first shot?

“Pfizer.”

“We only have Moderna right now, are you ok with that?”

“Yes. I don’t care,” then I asked, “Are many people saying they do care?”

“Quite a few.”

This baffles me. The vast majority of people in BC had Pfizer as their first shot… a mRNA vaccine. Moderna is also an mRNA vaccine and there have not been any adverse affects from mixing. Also research on the efficacy of mixing vaccines seems very positive.

When I was asked which vaccine I got after sharing my first shot, I shared,

A good friend asked on Facebook: “Which one did you get Dave?”

My response, “The one I could get… I’m leaving it at that because I want to encourage others to do the same.”

Now I am sharing which ones I got because I would hope others will mix and match as needed to get vaccinated sooner, rather than delaying. We are getting much closer to living with some normalcy. The only mix and match stories that I could find that were negative were related to concerns when shots were mixed accidentally, months ago, before the positive research was out, and one article saying the short term effects might last a little longer.

Meanwhile, anecdotally, I’ve seen quite a few Pfizer/Pfizer vaccine recipients take more than a day off of work after getting their second vaccine, and most people that I know who have recently received Pfizer/Moderna have found the side effects are lasting less than 24 hours.

The other research I’ve seen suggests that mixing AstraZeneca with an mRNA vaccine seems to provide an even more robust immune response. So, I hope that no matter if you had AstraZeneca or Pfizer first, you would be willing to take Moderna second, rather than avoiding mixing and matching and delaying your second shot.

Early warning systems

I received word last night that a retired colleague and friend died yesterday. Cancer sucks. I know there will be a time in the future when we will be able to beat cancer consistently. Even before that, I think we will develop very early methods of detecting it. We might prick our fingers once a month and hundreds of health concerns might be detected early on, or maybe we just go to the bathroom and the toilet itself will detect concerns by doing a daily water test of our waste.

Essentially, early detection will help us detect the cancer early and we can knock it out before it kicks the hell out of us. This will likely happen before we actually beat cancer altogether… we just become really good at detecting it early. “Kill a snake when it is small,” my grandfather used to say.

My wife has an Apple Watch. In a decade or so, most of us will have a device like this that will monitor our health and do daily diagnostics for us. It will monitor our heart rate, blood pressure, temperature, sleep patterns, and a whole series of other biometrics that will create a baseline for us, and let us know when things aren’t at homeostasis. We will get medical feedback that will become an early warning system for us when our readings are off.

Imagine getting a little warning from a wearable device that tells us that our heart is doing something that has been detected in thousands of people a month or so before they got a heart attack, and suggesting you go for a checkup… and sharing this data with your doctor. Imagine learning that you have the flu before feeling the symptoms, and this device tells you to stay home and not spread your contagion.

We aren’t there yet, but I look forward to the day when we can count on an early detection device saving our lives, and extending the lives of those we love and care for.

3 trips

On the weekend I spent some time putting water fed solar panels up on our roof. I thought 50 feet of flexible piping would be enough, but that only covered getting the water to and from the low garage roof, and not taking care of the piping also needed to get the water from the pool to the pump and filter.

Yesterday after work I bought more piping from a pool & hot tub store and then went to the hardware store to buy more connectors than I needed so that I wouldn’t have to make another trip.

Then I made another trip to the hardware store… and then another. I finally had all the proper connection pieces, but only after assembling 3 pieces together to replace one piece that was there previously. Without going into details, the small pump currently attached to the pool, which is too small to pump water up onto the garage roof, is attached by parts unique to the pump and so the transition from the pool to the new pump was not as simple as I thought it would be.

So, I continued my tradition of always having to go to the hardware store more than once whenever I do any kind of handy work. I’m glad it’s a short drive, but when I have to go a third time, it’s really frustrating. I ended up re-hooking up the old pump after dark, and will put everything together later this week, but probably not until the weekend, with a very busy after school schedule until then.

‘Measure twice cut once’ is a phrase you often here tradespeople say. Well, it seems mine should be ‘measure twice, visit the hardware store once’… but no matter how much I measure, how much I think I’ve prepared, I end up not realizing I needed another item, or buying the wrong item, or running into an unforeseen issue. Chalk up one each for those reasons last night.

The day I am able to visit a hardware store just once, and complete a full repair of project will be a day of celebration for me. But last night was not that night. Last night it took 3 trips to the hardware store. And now the task that I had hoped to be completed must wait longer to be done (again).

The longest day

Happy Summer Solstice! It’s hard to believe that today is the longest day of the year.

When the shortest day comes on December 21st, I’m ready for the days to get longer. It’s dark early and it feels like the right time to swing the pendulum back, and to start seeing more daylight. But June 21st seems too early in the summer to be at the maximum daylight length.

School is still in session, and the entire summer holiday is ahead of us. In my head the long, bright days of summer are just approaching. But every day from now until next December will get a little shorter.

There are reasons why the dead of winter is delayed until after the shortest day of the year, and why summer is hottest after the longest day… but intuitively it doesn’t make a lot of sense. This day just seems to come too early in the year. This timing does explain why the summer solstice was such an important event to pre-industrial humans. This is the day that leads to a bountiful summer, when the sun provides the greatest rewards. It’s a time when all crops have been planted and many early crops will already be ready, and ripe for picking. And so there is enough food for a feast, and the hard work of caring for crops and harvesting are ahead.

Now, the solstice is just an interesting fact, rather than a big celebration. But I always look forward to the summer and winter solstice. The winter solstice because it’s nice to think of each day getting longer as the winter approaches. The summer solstice because the whole summer lies ahead. So, while many don’t think of this day as special, I do.

Happy Father’s Day

I still haven’t spoken to my father yet, but I’ve got my kids here and dinner is being picked up as I write this. Sushi. All my favourites.

I spent the morning shooting a round of arrows followed by a quick workout. While I didn’t shoot my best, it was my first round where I scored all gold.

A success even if it wasn’t a personal best. I had a few line breakers that squeaked in, but as my buddy always reminds me, a 9 is a 9 and a 10 is a 10… take them when you get them.

My afternoon was busy. I installed my water fed solar panels on my garage roof. This took longer than expected and everyone was pitching in, but the hard part is done!

And food has arrived. To all the dads out there, happy Father’s Day! It’s time to have dinner with my family.

A rose by any other smell

I had the opportunity to stop and sniff the roses today. They were beautiful, and their smell… well their smell reminded me of bathroom spray.

Growing up, my mom always bought rose scented bathroom air deodorizer for all of our bathrooms… especially the main floor bathroom that had a very noisy fan and poor air circulation. If you ever used that bathroom for a ‘number 2’, you were sure to mask the odour with the rose scented spray. Now, decades later I can’t smell a rose without flashing back to the memory of bathroom spray and hints of fart.

If my wife is trying a new perfume out, a common complaint I’d have if I didn’t like it would be ‘too flowery’.

It’s weird how smell can incite such powerful memories. And weirder still how those memories can impact us so many years later. I don’t have a great sense of smell, but I will sometimes smell something and instantly I’m thinking about a memory, or thinking ‘this smell reminds me of something’, but not remembering what?

If you have have reason to buy me flowers, roses may not be the best choice. 😜

Good news on the vaccine front

I will admit that I’ve been critical of the vaccine rollout in Canada. I really thought that it took much too long to get things started. However, I now have to say that I’m very impressed with how things are going. Have a look at this chart as of yesterday:

It seems that Canada’s strategy of getting the first shot to as many people as possible is paying off. I get my second shot next week, and I just read that the new Canadian goal is to have every person from the age of 12 and up to be able to get their second shot by September… every person that wants it.

That’s the new challenge we face, how many people in our population will not choose to get vaccinated? With the Delta variant hitting the unvaccinated population extremely hard, Covid-19 is proving to be hearty and resilient. The Delta variant spreads very easily, and on average causes much harsher symptoms, putting more people in hospital than other variants.

Reducing the threat of this variant, and subsequent variants is best done with a comprehensive vaccine rollout. Reduce the likelihood of spread, and you also reduce the likelihood of mutation and new variants. The spread of measles provides a good lesson for us. Measles is preventable by vaccine and numbers have gone down for years heading into 2010. But the last decade has seen spikes due to anti-vaccine sentiment, and a larger population of unvaccinated kids in different populations.

Canada is lucky. For such a large country, we don’t have a massive population, and the population we do have predominantly lives in a narrow band near the US border. So, not many people, but mostly living in a concentrated area. This makes vaccine distribution easier on two fronts. The third and final frontier is the willingness of the population to do their part.

Our younger generation seems to be more willing to do their part than in other countries. As soon as the 18+ population were given the opportunity to get a vaccine in Canada, uptake has been good. Since younger age groups seems hard hit by the Delta variant in England, it is comforting to know that the Canadian population that had to wait the longest for their turn at getting the first shot have been so willing.

It’s good news all around in Canada, and so now as the vast majority of the population lines up for their 2nd shot, it’s my hope that we also see more people take advantage of their first shot. This is the challenge ahead of us. Not the rollout of the second shot, that is going very well. Rather it’s the rollout of the first shot to the population who seems hesitant to do their part. The closer we get to full immunity, the more likely we are to be protected from dangerous variants spreading through our communities… and our loved ones.

Public and private work

At Inquiry Hub students learn the difference between a working portfolio and a presentation portfolio. They don’t get electives in the same way a student in a large high school gets theirs. Instead of a Grade 9 looking at a large catalogue of courses to choose from, students get a couple ‘mandatory electives’… yet they end up with more choice and variety than students in big schools with many elective choices. This is possible because one of the mandatory courses is Foundations of Inquiry, where students get to choose their own topics.

Here is a Grade 10 student, Thia, describing her inquiries in her grade 9 year:

In Foundations of Inquiry, students create a working portfolio. Using OneNote, they share their documentation of work and progress with their teacher. They will include photographs, videos, and journaling, as well as reflections, progress reports, and copies of presentations done as part of the process. These notes are not public, beyond teacher access. In a way, these portfolios are the rough draft of what’s being done.

We also encourage students to publicly share their work. This can include on a blog or website, or a presentation beyond the classroom. It can include contacting mentors and experts and sharing what they have done. And it can include creating videos or doing presentations to family and community at school. These are public opportunities to share their portfolio, and this portfolio is polished and ready for sharing out in the open.

A daily journal like this is sort of a mix between the two kinds of portfolios. Writing every day, I don’t get to share polished work. I have no editors, I am generally sharing my first draft, looked over only by myself, once or twice, before scheduling the post to go live at 7:22am on most mornings… a random time I have selected and stick to on weekdays, when I’m up and writing before 5:30am. Weekends I publish later, and immediately after writing, rather than scheduling.

This is by all means a working portfolio. Some of my ideas are half baked. Some are fleeting thoughts expanded into a handful of sentences. Some are ideas like this where I give a long background before getting to the idea at hand. Some are thoughtful reflections that seem far more thought out than they actually are. And some really aren’t that good, and wouldn’t pass an editor, or even myself if I looked at it two days later.

A journal like my Daily-Ink is a constant work in progress, it is a working portfolio of ideas and thoughts. Yet, it is also very public. When I schedule a post, it automatically goes to RRS feeds, it gets put onto a Facebook page, and it is shared through Twitter and LinkedIn posts. It is put on public display on many fronts for anyone interested to see. It’s a glimpse into my mind, and it shows the rough edges. It is at once a draft and a final copy.

I don’t think many people would be comfortable doing this every day. I have to say that it is a huge commitment, but a rewarding one. Sometimes words flow and I feel an incredible sense of satisfaction. Sometimes I stare at a blank page with no idea what to write, questioning why I do this to myself? But, I wrote this one day and now share it as my blog tag line:

Writing is my artistic expression. My keyboard is my brush. Words are my medium. My blog is my canvas. And committing to writing daily makes me feel like an artist.

As I state in the post, “The act of writing makes me a better writer. The commitment to this act every single day is itself a reward, making me feel like I’ve accomplished something before I even start my work day.”

It’s not perfect, (in fact I found a typo in the quote above that I went back and changed). This is a working portfolio… it just happens to be one that I share publicly.

The Resilience of Students

We had our final PAC meeting of the year last night for Inquiry Hub. At the end of the Principal’s Report I did a quick ‘Thank You’ to parents, students, and teachers. One thing I mentioned when I talked about the students was resilience. I am so impressed with how resilient students were this year.

We’ve had students deal with family hardships that no kid should have to deal with. We’ve had students who have had their own struggles that they need to face. We’ve had students who have struggled previously that have stepped up and found ways to be more successful. These students are especially resilient, and may not even realize it.

We’ve also had many students who have come to school every day and just made the most out of this year. In many respects it has been a challenging year, one where things did nothing go as expected. But students have come together and created community. They have supported each other. They have found ways to thrive.

And they’ve learned so much! I’m absolutely impressed with some of the inquiry projects that were done this year. And when I’ve watched student presentations, I’ve seen slides that are so well put together that you would think they were going to a design school. They aren’t just putting information on a page, they are conveying a coherent story. While this is usually something we consistently see with seniors, this is now something that we are seeing at every grade.

And students are committed to helping each other. They have come together and showed how much they care for one another, and supported each other. The examples I can think of are plentiful, but also a little too specific to share here without asking permission. The point being that during a global pandemic, when I’d expect to see more individual concerns for student well being, I’ve instead seen resilient kids coming together to help each other.

We don’t always give kids the credit they deserve. They are amazingly resilient and at a time when many people are dealing with hardships greater than they normally have to face, our students, our kids, have been dealt a challenging school year and have made it through this year surprisingly well.

I can’t wait to see what these kids do when we are able to provide them a full school experience next year… it’s something I really look forward to. I’m already excited about what September will bring.

Aches and pains

I do a lot to take care of myself and for the most part, I feel good about my progress. But today I feel old.

I usually take in the attitude that age is just a number. I’m as young as I believe that I am. Today my age wins.

Saturday on my 5km walk with my wife, she decided to jog for some of it. I enjoy jogging at my wife’s pace and thought nothing of it. I will run on my treadmill faster than this, and for longer than the two sections we jogged for. Sunday after my archery I did an 8 minute leg workout that I usually do, and added about 4 reps of an assisted pistol squat, because I’m very slowly trying to get myself to the point that I can do these.

But by Sunday night my knee was hurting. I don’t know why, but think it might be running on uneven terrain rather than on the treadmill, or trying the pistol squat after my 8 minute workout, when my legs are fatigued. Then I got a hip cramp that night.

After this my shoulders and back tightened up and for the first time in several months I felt shoulder pain. I only did one exercise with my arms that was slightly different than my usual routine, and I intentionally did it with light weights since it was new. Besides, it was a bicep exercise, not a shoulder one.

This ache caused me to tense up my upper back and the tension between my shoulder blades was so tight, I had to push my back into doorway jams to work the kinks out several times during the day… basically using the corners of the doorway to massage the knots out of my upper back.

Old. That’s the feeling this morning. I feel like the rust has formed on my joints, and the whole machine is seizing up. This morning I’ll ride my stationary bike for 20 leisurely minutes, do some stretching, and that will be my workout. Tomorrow I have a massage booked and it will be a painful one. A lot of deep tissue work on my upper back, and hamstring work because my tight hamstrings tend to be the root of my leg and hip issues.

Maybe after that I can remember why I work so hard to take care of myself, remember to spend more time stretching, and start to feel young again. Maybe I need reminders like this to refocus me. When I don’t exercise, my back pain becomes chronic. But I have to say that it’s not fun to ache in several places at once, and while exercise usually keeps the rust away, right now this machine feels old and rusty.

This morning my age is getting the best of me… but I’m not done feeling young. I’ll work my way back to healthy, and oil these joints back to fully operational again. The alternative to this is being lazy and letting myself fall back into a life of daily pain, and feeling even older than I do today. No, I’d rather keep active and find my way back to feeling young again.
