Chapter 121: Catastrophe Bird_1

Inside Yihua Pharmaceutical Company.

Xu Changsheng eyed the first batch of vaccines within the equipment, some tension apparent in his demeanor!

They're here!

The first batch of vaccines had been produced.

Two types of vaccines, one therapeutic, the other prophylactic.

Although they didn't need to go through phase three clinical trials to be marketed.

But Xu Changsheng couldn't just toss them into the market for use either.

After considerable hesitation, Xu Changsheng directly called Yang Sheng.

"The first batch of vaccines is ready, we need some test subjects."

Hearing Xu Changsheng's words, Yang Sheng instantly became excited.

"Great! Wait for me... I'll be right over!"

After hanging up the phone.

It wasn't long before.

Yang Sheng arrived at Yihua Pharmaceutical Company with a team of several dozen people.

Seeing this, Xu Changsheng was momentarily stunned.

Because these people were not strangers...

Most of them were medical staff.
