Story is about Africa, primarily Somalia. I imagine vaccine hesitancy must be rising in the US as well, but this is about Africa.

Interestingly, our paediatrician in the US gave us a long lecture about why vaccines are important and this and that. He's an older gentleman and wouldn't brook any of my interruptions that I've been through this and to please proceed with the vaccination schedule and that I've had measles[0] when I was a young child and have no intention of subjecting my children to it. Presumably his insistence on the subject was because of hesitancy.

In the end, we got the usual ones but didn't give our daughter the COVID vaccine. I can't say it's a super principled position, except that I think I do want to minimize the number of vaccinations she gets to the ones that are the highest risk for her. That's the usual meningococcal, hepatitis for a neonate; the Tdap for an infant, and the subsequent measles et al. for older children. I think I'm content to leave the tail risk items in the tail.

0: I was eight months old, my parents were the only doctors in the rural Indian village, and consequently a local brought their very sick child to our home. The child was in the room for just a few moments before my mother rushed me to the other room. As it so happened it was too late for me. I became quite sick as well.

Perhaps the doctor deserves some slack.

"I'm not like those vaccine hesitant people, I just hesitated about a vaccine!"
arjie•56m ago
Haha you guys are funny. We went along with every one that he recommended. Just a straightforward Yes To All. The COVID vaccine wasn't on the list. No manual opt-out. There's a manual opt-in but I'm fine with things as they stand.

I should have known better than to mention that. For obvious reasons this one virus is a bit of a politicized subject and activates the outrage machine.

I've got no problem with our paediatrician. Rather like him, if I'm being honest. Wouldn't be going back for every subsequent appointment if I did have a problem. The "long lecture" bit is more affectionate than complaining.

uecker•11m ago
COVID vaccination for healthy children is not necessary because the benefit is small compared to the risk (but still considered positive and vaccination is recommended when there are certain risk factors). It is indeed unfortunate that this discussion is politicized.
AuryGlenz•54m ago
Considering many (most?) countries such as the UK, Germany, Australia, Spain, etc. don’t vaccinate healthy children for COVID because there’s basically no reason to, which presumably the doctor knows, he probably wasn’t disappointed. Having a blanket policy of vaccinating healthy children against COVID, especially now, was a terrible ideologically-driven idea that almost certainly drove more people to be antivaxers.
genuineresponse•1h ago
Covid is a serious illness. It can cause a wide range of effects from death, to myocarditis, to immune system resets, to long covid, to permanent scarring on the lungs, mood disorders, embolisms, and permanently reduced mental capacity.

Covid is not a tail risk.

Additionally, by not getting a vaccine, you potentially put people at risk who cannot get a vaccine -- immunocompromised folks, etc. Vaccinating your child also protects everyone in their communities.

Choosing not to vaccinate because you want to limit the number for no expressed reason is vaccine hesitancy. You have expressed a position of vaccine hesitancy here.

sedivy94•52m ago
Everything you listed are tail risks of COVID, even in individuals with comorbidities, and are far more characteristic of the early strains than what’s circulating today. The only exception in your list of side effects is myocarditis, which is also a side effect of the COVID vaccine. Furthermore, the vaccine’s target population is individuals over 65 years old, immunocompromised individuals, obese individuals… not newborns or infants.

Alarmism, militant shaming, and omission of details like the ones I mentioned above are three strategies that steer vaccine hesitant people away from taking vaccine advocates seriously. Personally, I would raise concerns about anything but COVID and ease up on the Newspeak.

eqvinox•16m ago
Except long term effects from COVID are not fully understood yet, especially in children. Feels like unnecessary gambling to me.
AuryGlenz•48m ago
In healthy children the chances of any of that happening are effectively 0, and while vaccine injuries and significant side effects are rare in their case it might actually be more likely. That’s why very few countries other than the US ever vaccinated healthy children, especially post-pandemic.

Almost literally everyone has and will continue to get COVID at this point. Not vaccinating your child, or all of the children in the US, won’t prevent that. I don’t know a single person that hasn’t had it, vaccinated or not. So, your child gets the vaccine. They’re then, what, maybe 50% less likely to get COVID for 6 months? Not exactly moving the needle as far as community transmission goes. This isn’t 2021 anymore.

If we had a better, longer lasting vaccine you might have an argument. Very, very few parents are going to do the COVID vaccine for their child every year. At the very least you’re risking them picking up something more serious just by going to a clinic or pharmacy to get it.

sfn42•35m ago
I don't know that I've had covid. My SO had it twice during the pandemic and i was testing myself daily but never tested positive. I like to joke that I'm immune. Of course I also had the vaccine but I understand that I should still get the disease, just less severe.

Anyway I haven't tested since the pandemic so I wouldn't have known if I'd had it afterwards.

rkomorn•26m ago
Did you do self-tests?

I've been exposed three times (twice by my SO) and only tested positive once, but I had symptoms both other times as well.

All my tests for those were done at home and I wouldn't take "I did it wrong" out of my equation.

sfn42•21m ago
Yeah, did self-tests and have thought the same. I definitely followed the instructions and my SO is a nurse so she knew how to do it, but who knows. I also had some very mild symptoms at least one of the times.

Could be something like our viral load wasn't high enough to register on the test, maybe our immune systems just dealt well with covid.

arjie•17m ago
Considering the response to the subject this is probably a bit risky, but I also like to joke that I'm immune.

Except I like to claim it's because of an intentional approach

https://wiki.roshangeorge.dev/w/Low_Dose,_Frequent_Exposure

Not very likely, but amusing nonetheless.

diordiderot•18m ago
Covid was literally 10x more dangerous than the vaccine for those without comorbidities, but it's played out now. The vaccine is about as effective as a flu jab.
uecker•42s ago
This seems like a bad way to phrase it. The vaccine is certainly a lot (many orders of magnitude) less dangerous than just 10x the dangerous of COVID. Maybe you wanted to say that the risks from the disease is only 10x more without vaccination than with it?
closewith•17m ago
You are incorrect and are harming public trust in vaccination with your comments.

COVID-19 vaccines are no longer indicated for most healthy children (or most healthy young adults) in most jurisdictions as the risk benefit analysis no longer supports it.

> I imagine vaccine hesitancy must be rising in the US as well, but this is about Africa.

You strike an interesting point.

From a scientific PoV, vaccine rejection in the West is pretty much unjustifiable according to mainstream medicine. But the not-worst-case, fairly bad outcome is kinda manageable. Your child gets measles, is probably OK, but if not, goes to an expensive hospital and will probably be fine. Even without vaccinations, it's probably not a life or death scenario. I'm not saying it's good, only that the price tag is likely low.

But of course it's completely different in poorer countries, many places in Africa among them. These are also places with poorer education on average, I'd imagine. And what do they think when the West is sending them (or they're buying out or scarce resources) stuff that we refuse because it's "dangerous"?

And if you get a measles outbreak in Somalia, you won't be worrying about childcare and copayment, it will literally be life and death.

People who peddle anti vaccine BS should think about this too.

What an incredibly selfish point of view. Both for ignoring the risks of measles in your own child, and more importantly, for completely leaving out of the equation the likelihood that they will spread it to someone who for medical reasons cannot be vaccinated or for whom the virus is even more dangerous.

rich_sasha•18m ago
Have you actually read my post? Or just the first 130 characters - and even then, maybe you missed the bit about

> From a scientific PoV, vaccine rejection in the West is pretty much unjustifiable according to mainstream medicine.

The post is against anti-vax.

gspr•12m ago
Yes. Did you read mine?

I do realize you mean to critique anti-vaxxers. That's good. But the way you paint measles as a minor inconvenience in the west is really bad.

arjie•10m ago
Pity you got whacked. I think people read the "you will survive even getting the disease" and assumed you were anti-vax when the reasoning is second order: if the First World won't use these drugs it signals danger to those who don't have the tools to independently verify.

An interesting angle, though I wouldn't say I agree. As one example, I believe all of us in India routinely receive the BCG vaccine against TB right after birth. It's not routinely done in the US (unless I'm wrong and don't remember it). The US choosing not to do it doesn't make Indian people want to not get it.

More likely, there's something else that's making people worried about the standard vaccines.

> I do want to minimize the number of vaccinations she gets

Imagine saying this about anything else that's good for children. I want to minimize the amount of food she eats. I want to minimize the number of friends she has. Insane mindset, tbh.

So what's the downside of the covid vaccine? A little arm pain for a day or so?
beeflet•26m ago
There is no downside to taking any vaccine. I've taken 4 different covid vaccines alongside all their associated boosters when they were available for free.

For anyone that isn't afraid of needles and a little arm pain, it's worth it for the peace of mind alone.

4gotunameagain•21m ago
The downsides of a very new, experimental vaccine that the covid vaccine is, have not been clearly established yet. Partially due to tribal, adherent behaviours like the one you are displaying right now.

I think it is a reasonable point of view to not want to be the testbed for vaccines that were also rushed to the market to reap the profits, let me remind you.

Oh and, I've gotten the vaccine. I'm just not tribal about it.

ZeroGravitas•21m ago
So minimize the risk, not the number of vaccinations.

Decisions that take you in opposite directions.

allan_s•14m ago
Everything has risks, every time you go out of for a run you can injure yourself, fall badly on the head and die. Nearly all Life decision are about risk/benefits
arjie•21m ago
Haha, I can simultaneously try to minimize neither kinds of food nor number of friends while minimizing number of medical interventions. I suppose to some people all three of these must either go down or all three must go up, but I think I can move the three for my child in different directions with different intensity.
fithisux•1h ago
Vaccines can help initially, but in the long run they are a band-aid to the economical divides and exploitation.

If wars motivated by resource exploitation and class-system were not a thing vaccines would see a limited use.

Unfortunately vaccines are seen as holy totems whose real purpose is to sweep under the rug the real systemic problem.

Just like in ancient years did the idols.
