Vaccine Effective From Date

[tiggerblue10]

Sorry if this has already been asked but once the vaccine is administered, when is it effective from? I read it's 28 days but is this after the first or second dose?

[Buenchico]

It's 7 days after the second dose which, as there need to be 21 days between the two doses, makes it 28 days after the first dose.

[ummmm]

First dose I think. I'm sure I heard the second dose is administered 21 days after the first.

Cheers both :o)

Buenchico you take medical info from the BBC? That is very scary to me :(

[ummmm]

It's not the BBC giving the medical advice....jeez.

the BBC are probably the most reliable media source. They would sooner get the news late than get it wrong. Like other media ssources, they also take pains to put the story into ordinary English rather than medical/statistical jargon.

RNA cannot change DNA the former is a much simpler construct for a start. Stop reading the anti vaxer's BS.

I wish I never commented. :(

You might want to read this. It might reassure you but of course anyone who beleives this is a conspirocy and the scientists and goverments are lying to us won't be convinced by the full fact checks

[tiggerblue10]

You are entitled to your opinion, Ukanonymous but that said, I've read that these vaccines were being worked on and tested for other viruses as well.

well take it from us then

if you are thinking about not having the vaccine - another thread - then yoy dont have to worry about when it works from

[tiggerblue10]

Forgot to ask - do we know how long the vaccine lasts? Will it be given yearly like the flu vaccine? Or is none of this known yet?

[theprof]

Tiggerblue10, we're still working on it and we can't answer the question right now. Time will tell.

[bednobs]

sorry in terrupt the prof, do you know if people taking monoclonal antibodies will be able to have the immuniation?

[tiggerblue10]

Thanks, TheProf, obviously far too early to tell.

[theprof]

Bednobs, yes indeed patients taking mAbs are likely to be offered the vaccination.

Monoclonal antibodies are already undergoing clinical trials to demonstrate their effectiveness against Covid-19 and right now, I like what I'm seeing. They seemed to have worked on Trump earlier in this pandemic too! The problem with mAbs is that they are eye-wateringly expensive to produce and the production facilities need to be ramped up. Durability is also an issue with them. The big advantage of course is that the right ones are immediately effective against Covid-19. The so called "convalescent plasma" may well be the way forward. One day, they may replace vaccination if the virus is still with us.

I was involved with this research way back in 2004 after the first recognised cases of SARS came to light and it has turned out to have provided a head-start in Covid-19 vaccination development.

SARS-CoV-1 was on the planet between November 2002 and around May 2004 and simple, public health measures such such as masks, isolation, quarantine and travel restrictions all proved to be its downfall. I sincerely hope that Covid-19's duration is similar or less because we have put precisely the same measures in place.

[theprof]

Oops, typo alert! I intended to say I was involved in SARS research way back in 2003 not 2004. My apologies.

// and right now, I like what I'm seeing. // monoclonal ab

prelimary studies show they dont work that well ( NEJM I think - implying that it is another trump non starter )
