32 分钟For Scientific American Science Quickly, I'm Rachel Feldman.
This is the final episode of our three-part series on bird flu.
On Wednesday,
we met scientists who are getting their hands dirty with dairy cows and poultry to better understand how H5N1 bird flu is spreading.
Today we'll take a look at efforts to create vaccines for H5N1 and learn why eggs are so critical to the vaccine making process.
Our host today is Naima Marcy, a multimedia journalist based in New York City.
Here's Naima now.
It's barely 10 a.m. in San Antonio, Texas,
and it's nearly 90 degrees in the middle of May,
while the rest of the city steps out in sandals and shorts.
I'm watching a team of scientists at Texas Biomedical Research Institute.
They're rummaging through metallic shelves to find the extra layers of protective gear they need to start their day.
Scrubs, gowns, gloves, shoe covers, hair nets, and long white coveralls.
So we need to change all our clothes and that's what we have these cabinets there.
That's virologist Luis Martinez Sobrido.
He observes with a keen eye as two members of his lab dress up for the next shift.
You take everything out, only the scraps and the bunny suit.
They also use this head net to cover the head.
I don't have that problem.
I don't need that.
