Can someone answer a question please.

I guess a flu jab last 12 month in our bodies. That's why we need a new one the following year.

So can anyone tell me how long the Covid jabs stays in the body please?

No, we don't know yet. That's among the reasons why a) the studies on the vaccines are ongoing, and b) some of the advice might be more cautious at this stage.

(Imperial react studies show antibody levels, but they're pretty short term at this stage)

Generally - not so much at the moment - flu viruses mutate very quickly, while corona viruses like Covid mutate more slowly, which is one of the reasons why we need to rejab every year.

The virus mutates so each year we need a slightly different vaccine to take account of that.

The immunity that the covid jabs produce has an uncertain longevity, as they've not been in use for long enough yet. It's about having enough immunity that's effective and lasts. Pfizer issued an update from their trials that showed good immunity lasting 6 months so far. The other manufacturers will do likewise I'm sure, once the data becomes available. They're looking at combining flu and covid jabs, for an annual booster. The flu one can last longer than a year but the various different flus are monitored and they pick the ones that are predicted to be the most trouble, to put those in the jab for flu season.

The UK is discussing autumn boosters this year for covid, as it's approaching the annual date of the first ones done plus they may use a tweeked one that's geared to the newer varjants. This will be particularly important for the over 70s etc, who suffered more severely, in general on average.

It's not so much as sticking around in the body like drug metabolism, it's how effective our adaptive immune systems are primed to mount an early response. Influenza genomes drift and shift (genetic drift through mutations and shift through recombination of hemagglutinin and neuramimdase regions). Flu is seasonal so we attempt to predict which strain will be predominant based on those in the southern hemisphere season. Coronaviruses are relatively stable and I don't think there's much recombination going on so no way to predict how long immunity will last.

Tldr: don't know.

Work on this is ongoing, I did a blood test for antibodies this week as part of a research project. Was positive on a lateral flow type test for antibodies having had Covid in Dec & jabbed in Feb...second jab due in April.

I don't know in all cases, but I know in some research they're differentiating natural and vaccine induced immunity by looking for S antibodies for vaccines (spike) and N protein for infection (can't remember, it's not in the vaccines).

I'd read 6 months for the Pfizer one, not sure about the others.

I think the issue is that it's six months so far. (Like, how long will I live? Do I say 35 because I've lived to 35, or do I not know because I might live to be 100?)

Pfizer said 6 months. Moderna said a year. We don't know as not that long has passed since they came out.

surrounded by twinkly lights

Various medical journals report that the flu vaccine is about 6 months worth of protection

Covid-19 vaccines results are still being reported on

I am currently working on the new Covid-19 study, which is to assess how long the antibodies remain in the body. Just now there is no measuring tool so it’s quite an important continuous study. At the moment, study volunteers are being tested every month till April 2022

I've been helping with a study that sounds similar. To begin with it was on antibodies from those infected... now they are looking at how we react with the vaccine. I'm also on monthly testing. However I've been told unusually I've had very little dip in my antibodies since they began testing me. Apparently that is not the norm.

The antibody studies are interesting.

And make my head hurt. Immunology is hard

As the first generation of Covid vaccines AZ, Pfizer and Moderna have surpassed expectation so whilst 6 months may not seem a long time - it is a huge achievement.

No doubt the next generation of vaccines will be improved upon and could be available later this year.

Absolutely. This is just "stab at it, take one". (No pun intended

)

I fucking love science

The people who were vaccinated against the old SARS corinavirus 18 years ago still show excellent immunity. This novel corinavirus acts quite similarly and most experts believe immunity will be similarly long lasting.

The 6 month figure comes from research (ongoing) involving the first people to take part in human trials of the covid vaccines... Which was about 7 months ago. The easy scientists speak is to say this group still has good immunity after 6 months, so we can guarantee 6 months immunity.

The trouble is that unknowledgeable "journalists" pick up on this and write articles "panic! Jabs may only last 6 months"
