I dont think you can have 2 different types mixed together, but I may be wrong here.

Actually various medical groups are talking about mixing vaccines (1st shot one vaccine and 2nd shot a different vaccine) as a way of potentially raising efficacy.

One would think if they can be mixed then must be made of the same thing.

Agreed, JGF.  I've read recently that the Chinese are considering a third "booster" shot to enhance it's efficacy or combining Sinovac with Sinopharm/  It will be difficult to get first and second jab here.  Sadly, not  sure if that would ever happen here. Maybe it won't be necessary.

Actually no... it is because they are different that they enhance the immune response (or at least that is the prevailing hypothesis).

And they're not talking about 'mixing them' the idea is you'll have one shot of one vaccine then later on a second shot of a different vaccine.

The idea is that one shot is followed by a different type of shot is not a new idea, there are two different types of pneumococcal vaccines and sometimes they're used together to enhance response.   And the Russian Sputnik V Covid-19 vaccine uses two kinds of adenovirus in its prime and booster doses to deliver genetic instructions to the immune system. The first jab uses a harmless common cold virus (Ad26) and the second, given 21 days later, uses another safe (but gene engineered) cold virus (Ad5).

The idea does not have universal support amongst the medical community.

 

Me I'm happy to say I don't know and I'll wait for the experts to do some more research.

Well if most shots require two dosages then shouldn't it be that a third of a different type might be the answer rather than half of one plus another?

Most shots don't actually 'require' two dosages to work... the first shot will work by itself, it's just that the seond shot gives a boost (thats why they call it a booster shot).

So it's not really half of one plus another... it's one of one type and one of another type.

One of the reasons for this is that the body can respond with an immune response to the harmless carrier as well as to the intended viral fragments... and if it does then it destroys the carrier before it gets a chance to 'learn' about the virus.  This can be reduced by using 2 different carriers as the body doesn't get to learn about the harmless 'carrier'.

Well some organisation called, Center of disease control and prevention say.

If you receive a Pfizer-BioNTech or Moderna COVID-19 vaccine, you will need 2 shots to get the most protection. COVID-19 vaccines are not interchangeable. If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot.  You should get your second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.

I think best to stick to the advice of a former leader and inject disinfectant. That should clear the system :smile:

Our politicians and health experts in Canada have informed us that the second shot will be whatever vaccine is available.  I was informed by the nurse yesterday, when I got my shot, that they are all basicly the same vaccine with differnet manufacturers.  When I questioned her about it she told me that information comes from the leader of our province and the leading health authorities in our country.

I am NOT saying that I believe that.  I am saying if one believes the leaders you will swallow a lot of bullshit.

If there basically the same why do they offer different amount of protection like from 50% to 94% or whatever it is? So now if I got a Chinese shot with 50% and one of the others Im getting up near the 100% marker.  

The only thing I believe is one day we will know if there's more ham than good done.
