"Every vaccine is a little seed,
He will eventually grow into a warrior who guards life and health."
Say this affectionately
She is Li Mingxi of the new crown vaccine research and development team of Tsinghua University School of Medicine
She has just graduated with a Ph.D
Not long ago at the graduation ceremony of tsinghua university graduate students
Because of its excellent performance in anti-epidemic scientific research
He was praised by principal Wang Xiqin by name
Loved creatures since childhood
Li Mingxi, who is full of curiosity about the mysteries of life
I have always wanted to be the first discoverer of the phenomenon of life
After being admitted to Tsinghua University
She firmly chose to major in biological sciences
However, in my freshman and sophomore years, my grades were not ideal
Just entered the Tsinghua campus where the masters gather
She had a deep sense of loss
"I used to think I could learn anything.
When I go to college, I find that others don't learn."
Went through a tough time of self-denial
She struggled to adjust herself
Insist on daily study planning
Constantly looking for the right direction for you
After her sophomore year, she found herself good at experimenting
So I slowly rebuilt my confidence in the experimental project

Early 2020 The COVID-19 pandemic struck suddenly
Professor Zhang Linqi of Tsinghua University quickly set up a scientific research team
Carry out research and development of COVID-19 vaccines
The eighth day of the first lunar month of the New Year
Li Mingxi, who was still at home for the New Year, immediately returned to school
Become the first full member of the vaccine development team
The next 200+ days
She followed the team throughout the lab
Day and night with the virus "grab time"
She said she wanted her to participate in the development of the vaccine
Can be combined with other vaccines
Increase global vaccine coverage
Delay the spread of the epidemic
The picture shows Professor Zhang Linqi's team of doctoral students Wei Jing, Li Mingqian, and Lei Yuqing (from left to right) measuring the neutralizing antibody content in the serum of mice and evaluating the immune effect of the vaccine.
Team member Lei Yuqing said
Li Mingxi's attention to the details of the experiment impressed her
Some very basic operations are also checked repeatedly
When evaluating vaccine efficacy
She collects serum from dozens or even hundreds of mice every month
Due to the continuous emergence of variants of the new crown virus
As a result, she has evaluated 12 vaccines
Efficacy was evaluated on 14 mutant strains
April 2021
Li Mingxi was busy with an experiment
Stay up late every day to catch up on data
However, the expected effect was never obtained
At the same time, she also had to prepare for the departure for Nanjing
Represented the team in a youth speech program
"I couldn't stop the weekend,
I went to the lounge and cried a few times.
Then dry your tears and continue to do the experiment."
In this show
Li Mingxi accepted questions from young students from many countries
Narrated on the road of "new crown vaccine research and development"
How China can act quickly
Increase vaccination rates
It is one of the effective measures to strengthen epidemic prevention and control
This form of popular science has been affirmed by the tutor Professor Zhang Linqi
Through this popular science experience
Li Mingxi realized that she should go more from behind the scenes to the front of the stage
Answer questions from an easy-to-understand perspective for your audience
Build bridges to popularize scientific knowledge to the public

May 2021
The new crown vaccine that Li Mingxi participated in the research and development of has officially entered the clinical trial stage
December 2021
Research results of Professor Zhang Linqi's team
The combination of ambavir monoclonal antibody/romizumab is approved for marketing
And was incorporated in March of this year
Diagnosis and Treatment Plan for Novel Coronavirus Pneumonia (Trial Version 9)
Li Mingxi said that every R & D team progresses
It's all human progress
After graduation, she was obsessed with scientific research
Choose to westlake University Emergency Medicine Research Center
Continue research and development of new vaccines and antibody drugs
In her opinion
Most of the failures on the road to scientific research
But moments of success are like stars lighting up the darkness in an instant
This is the charm of scientific research
"Like and recognize the value of scientific research,
Enjoy it without feeling hard"
"Although the trajectory of life has taken a thousand turns,
But the original mission cannot be changed."
Principal Wang Xiqin said in his graduation speech
Every challenge
It's all a test for the younger generation
On the road to scientific exploration
Closely link individual struggles to the destiny of the country and the times
Only then can we be more courageous in exploring new frontiers in the world of science
PhD student Li Mingqian
Congratulations on graduation!
Researcher Li Mingxi
Thank you for your efforts in the development of a COVID-19 vaccine
Thank you for your new contribution to China's scientific research!
