Do we know yet how long the covid vax is good for?

[The Blue Flower]

Are the experts projecting this to be a yearly shot?

1. i don't think we know

but i'm marking this thread in case someone does.

2. Great question, I never considered that it won't last forever like our childhood shots. Perhaps a

booster down the road.

3. How long are the flu shots good for?

I look for these Covid vaccines to be given every year just like the flu shots are, at least for the foreseeable future. Look at all the mutations, you just know that Big Pharma is working on booster shots.

9. Flu shots are different.

The flu is actually a collection of diseases that share a name and similar characteristics. Each year a different strain, or strains come around. Researchers make an educated guess about which version will be circulating, and create a vaccine targeting that strain. So the reason for a new flu vaccine is that it is a different disease you are fighting each year, not that the vaccine wears off.

So far there are only a few strains of the coronary that impact humans in a serious way - SARS and MERS are the two I'm aware of. So this vaccine isn't targeting a collection of disease that are constantly changing - so the question will be primarily about how long the immunity lasts (like it is for the measles vaccine, for example), rather than the guessing game researchers play every year to create the influenza vaccine.

4. I don't think it's lifetime like smallpox immunity.

5. Best guess is this will need an annual booster

6. They are uncertain

The last article I read about it (NYT or WaPo), had a discussion about post vaccine guidelines. The experts appeared to be at a loss over its time line. The general consensus I got from my read was that just as the flu shot is updated annually with what the expected flu variations will/are, so too would a covid shot.

The big concern was how fast the virus is mutating, and how many different mutations were popping up. It then went into more scientific specs that were above me. The specs had to do with protein on specific spikes, types of mutations, less "sticky" more "sticky", less virulent, more virulent, easier to spread, harder to spread. Umm, mostly they just are uncertain what is going to happen.

7. I read they are considering combining it with the flu vaccine for one annual shot But

they don't know for sure

8. Partially depends on how the virus mutates. n/t
