Personally, I don’t think it is worth getting the vaccine if you are under 40. According to this paper in the BMJ, for people aged 18-29, per covid hospitalisation prevented, an MRNA vaccine will cause at least 18.5 severe adverse events. A serious adverse event is: An adverse event that results in any of the following conditions: death, life threatening at the time of the event, inpatient hospitalisation or prolongation of existing hospitalisation; persistent or significant disability/ incapacity, a congenital anomaly/birth defect or a medically important event, based on medical judgement.
This decision also depends on what you think the risk of long covid is, but I personally think it is extremely low, as I discuss in the comments here.
It’s worth noting that the JCVI in the UK, which I think has been one of the most sensible bureaus on vaccines doesn’t offer the booster to people under the age of 65 unless they are in a high risk group or caring for someone in a high risk group.
I think this is assuming that someone under 40 would be considering getting the vaccine because they’re concerned about getting hospitalized for covid, but that’s very far down my list. Instead, the main things I want to prevent are (1) getting reasonably covid-cautious elderly relatives sick, where large family holiday gatherings are a decent portion of their annual risk and (2) having to cancel plans because I’ve contracted covid and am expected to isolate.
(Your comment also seems to conflate “under 40” and “under 30″)
As mentioned in my other comment, unless the people you are visiting are hiding at home all the time, you are not going to have much effect on the chance they get covid over any six month period. you might just bring it forward a bit time. but if they are living a relatively normal life eg going to shops (as I think they should) then it’s not going to make much difference since covid has been let rip in the US.
Re (1) I think you could do that with lateral flow testing rather than taking a vaccine that may be net harmful to your health. The false negative rate of a LFT is much lower than the protection against transmissible infection you would get at any point after having the vaccine.
I meant to say under 40. Given that the ratio of severe adverse events for 20s-30s is >18.5:1, I would also expect it to be bad to get the vaccine aged 30-40 given the extremely low health risks of getting covid in that age group.
Surely your self-estimated chance of exposure and number of high-risk people you would in turn expose should factor in somewhere? I agree with you for people who aren’t traveling, but someone who, eg, flies into a major conference and then is visiting a retirement home the week after is doing a different calculation.
I don’t think that makes much difference because I don’t think it has much effect on the total number of infections—you would really be changing the time at which someone gets the virus given that we’re not trying to contain it anymore.
One way round the concern about visiting the retirement home would be to do a lateral flow test before you go in. If you’re seeing extremely vulnerable people a lot, then it might be worth getting the vaccine. But the IFR is now lower than the flu for all ages and I think should be treated accordingly
I think the people I know well over 65 (my parents, my surviving grandparent, some professors) are trying to not get COVID—they go to stores only in off-peak hours, avoid large gatherings, don’t travel much. These seem like basically worth-it decisions to me (low benefit, but even lower cost). This means that their chance of getting COVID is much much higher when, eg, seeing relatives who just took a plane flight to see them.
I agree that the flu is comparably worrisome, and it wouldn’t make sense to get a COVID booster but not a flu vaccine.
Note that the serious adverse events (SAEs) that were recorded as attributable to the vaccine in the study were much more mild:
Of the 12 SAEs reported in the intervention arm of the randomised controlled trial (RCT) for BNT162b2 (n=5055), three were found by blinded investigators to be attributable to the vaccine, providing a rate of 1 in 1685 (3/5055).19 The three SAEs considered vaccine related included: moderate persistent tachycardia, moderate transient elevated hepatic enzymes and mild elevated hepatic enzymes.
Seems a bit misleading to list those much scarier sounding SAEs (as the paper does as well) like death and birth defects when none of them occurred in the study.

They aren’t: they are being very cautious.

Everyone in our family is already testing before each visit with our most vulnerable relatives, which is additional protection on top of the booster.
But even if this were not a factor in my life, (2) would still be sufficient.
