That tells me that it's actually been fossilized, this pollen.

The new vaccine had twice the impact on these last couple of viruses as the old vaccine had, and we immediately started using this.

In the vaccine area,

A different pollen signature, if you like, or a different pollen fingerprint.

Now, retro vaccinology is just one technique within the ambit of so called rational vaccine design.

He advocates for vaccination.

The vaccine is given by injection.

Vaccines were promised to developing countries.

Pollen is produced by the anthers of flowers.

They get paid by pollen and nectar, to move that male sperm, the pollen, from flower to flower.

These are little bits of individual grain of pollen there and there, and here is a what you see as one little yellow dot of pollen, when you look in a microscope, it's actually made of thousands of little grains of pollen.

So they make nectar as well as pollen.

So let's explore how vaccines work.

And of course, they're made to carry this pollen.

The vaccine will probably be useless.

These are little bits of individual grain of pollen there and there, and here is a what you see as one little yellow dot of pollen, when you look in a microscope, it's actually made of thousands of little grains of pollen.

They build up a static electric charge and the pollen jumps on them and helps spread that pollen from bloom to bloom.

So, I'm here to trumpet vaccines for you.

So that's really how vaccines work.

The vaccine effort though is really quite different.

That means they can't the pollen in their bloom can't fertilize themselves.

That's a geranium pollen.

But anyway, take a look at its pollen.

Now, pollen from plants, which are wind dispersed

Now the way that plants transmit that information is through pollen.

You've heard about the vaccine we're stockpiling.

So this, for example, when you see bees flying around these little plants, and they're collecting pollen, those pollen grains that they're collecting, they pack into their legs and they take it back to the hive, and that's what makes the beehive, the wax in the beehive.

That little hole in the middle there is for the pollen tube, and when the pollen finds its special female spot in another Morina flower, just on the right species, what happens?

Most pollen that causes hay fever for us is from plants that use the wind to disseminate the pollen, and that's a very inefficient process, which is why it gets up our noses so much.

A cedar tree releases clouds of allergy inducing pollen.

We don't see scenes like this anymore because of vaccines.

Hundreds of millions of dollars were spent and flowed to accelerating vaccine manufacturing.

So here's a comparison of several of these new vaccine technologies.

So, that's 20 micrometers across, that pollen grain there.

But not all pollen is quite so simple looking.

So, what are pollen's properties? I hear you ask.

First of all, pollen is tiny. Yes we know that.

It's how the earth got made, how the wind continues to pollinate.

Seth Berkley HIV and flu the vaccine strategy

Without a vaccine, these responses would have taken more than a week.

Pollen is a flower's way of making more flowers.

Like I said, pollen carries the male sex cells.

Pollen is tiny. It gets on to things, and it sticks to them.

And that's actually rather useful for forensics and so on.
