Will the definition of fully vaccinated remain two shots or will it change to three?

DBH was asked specifically about this a couple weeks ago, she said they are not going to change the definition of fully vaccinated. She also said that right now there's no evidence that the general population needs boosters. The only people who show waning immunity at this time are: * Those who are very old and/or frail * Those who are immunocompromised * Those who got 2 doses in a shorter (3 or 4 week) interval, in contrast to the vast majority of us who got them 8 weeks apart, which was primarily: LTC residents, LTC staff, and some health care workers. Not sure what tomorrow's announcement will be about, but my guess is a comprehensive plan to roll out boosters to the 3 groups above. I don't think general boosters are coming at this time.

At least two First Nations in BC are calling for boosters for elders in their communities: [Wet'suwet'en](https://www.cbc.ca/news/canada/british-columbia/wet-suwet-en-first-nation-calls-for-urgent-booster-shots-after-covid-19-deaths-positive-tests-in-community-1.6222472) [Lake Babine](https://www.cbc.ca/news/canada/british-columbia/lake-babine-booster-vaccine-covid19-1.6223900) I expect this will be discussed tomorrow and wouldn't be surprised to hear that boosters will be offered to seniors in First Nations communities.

I saw some of the initial numbers from a UBC study looking at vaccine antibodies in the LTHC/group housing environment. It drops about 50% after 5 months past D2, which is probably why these three groups are getting prioritized (as most would have gotten D2 in April/May, if not even earlier back in Jan/Feb) For genpop, since we got our D2 in May/June, I’ll take an uneducated guess and say if the govt is rolling out D3 it’ll be in the new year.


corvideodrome

It’s unfortunate that the (potential) D2 efficacy dip might sync up with the holidays/end of the year for many people. Hopefully any waning of protection might be less-pronounced in the general population; a post-holiday-gathering spike wouldn’t be fun.

We're still waiting to see what happens with our 8-week delivery schedule, mostly by watching the UK. So far, so good in the general population.


Delicious-Tachyons

> she said they are not going to change the definition of fully vaccinated. Good. I don't need a booster for now.


ygjb

Do you have evidence that illustrates that?


Delicious-Tachyons

Sure let me draw a blood sample and get an antibody titer. (?) I had my two doses. Until they can vaccinate the rest of the world, I shouldn't be in a position to receive additional doses. I'm a normally healthy 40-something.


ygjb

Sure, your first sentence outlines the test that would be necessary. Just a lot of folks making baseless claims, and I 100% agree with you on the rest of the world getting vaccines first, the main reason I wanted a third shot before is for international travel before the US and other countries indicated they would accept mixed vaccines.


Delicious-Tachyons

> the main reason I wanted a third shot before is for international travel before the US and other countries indicated they would accept mixed vaccines. Me too. Luckily that was fixed!


Modoger

The elderly and the immunocompromised are already having their third shots. I had mine a week ago. Edit: curious why I got downvotes here for stating a fact? Oh the internet.


coobrowning

Though none of the elderly living outside retirement facilities seem to have theirs yet. Hopefully that comes soon.


s0rmr

Awesome, thanks for that!


columbo222

No worries, again I want to clarify that this was based on what she said 2 weeks ago and I have no inside info about what tomorrow's announcement will hold :)

I imagine it will be at least six months. Ethically it would be borderline for us to vaccinate our general population a third time (under 65) before billions of people who don't have access due to Western hoarding.


Smoeey

I’m going to go out on a whim here and assume they have data of when/if the body becomes less immune to covid. Therefore, they will probably have dates tagged on the last dose to be considered fully vaccinated. I.e. after 12 months you’re no longer considered vaccinated. (This is full of assumptions and opinions)


dramatic-ad-5033

I reckon we’d see a really low uptake for the boosters if normal people were offered them


timmywong11

Since Jan 2021, UBC has been doing an ongoing study with VCH on vaccine efficacy and antibodies in the LTHC/group housing populations. So yes, there is data to support whatever decisions are being made


corvideodrome

It’s possible that numbers out of other countries with similar extended-interval dosing (like the UK) may help as well? Though there may be confounding factors admittedly


s0rmr

The vaccine doesn't provide immunity it reduces the severity and duration of symptoms.


Smoeey

What? of course it provides immunity, there’s a 90+ % immunity factor of the vaccinations, the symptom severity is a plus. This is why people can go to large events vaccinated and the spread is still low.


burnabycoyote

> there’s a 90+ % immunity factor of the vaccinations It is very difficult to find data about this. The CDC, Sinagpore and Israel have definitely stopped publishing it. Not sure about the UK, but I can't find it. Data from BC like most places that don't randomly test are suspect because they don't detect symptomless/mild cases. Even if data were available, some respectable Canadian scientists seem ill-equipped to extract the necessary information from it (an exercise in Bayesian statistics). Here is a particularly sad effort of one who gave up: https://www.mcgill.ca/oss/article/covid-19/statistics-behind-breakthrough-infections


PlanetaryDuality

I doubt they would change that requirement until everyone has had ample time to get a booster. They waited until yesterday for two doses, people have been able to be fully vaxxed for months.


[deleted]

I imagine it will change eventually but in terms of vaccine passport I don’t imagine 3 would be a requirement until everyone can get one


dachshundie

A good rule of thumb is that the US, despite lagging behind in vaccinations, will likely have the best and most trustworthy data for the western world. The US CDC came out with an 8-month booster shot recommendation in late summer. I don't think that was arbitrary, and I would imagine we will follow suit. Edit: Lmao - hope all of you who downvoted me saw today’s announcement. Sorry for providing a logical prediction.


crap4you

If they are giving everyone booster shots, they’ll have to open up some more clinics. Can’t do them at pharmacies or doctors office as they are all packed with people getting the flu shots right now.
