【Hot spot】Just now, Academician Zhong Nanshan's lecture brushed the screen! Respond to hot topics!

On the afternoon of the 15th, in the National University Anti-epidemic Lecture Hall, Academician Zhong Nanshan will systematically analyze the characteristics of the second wave of the national (Omicron) epidemic, introduce its biological characteristics and pathogenicity
.

Taylor listened for a while and took a few screenshots
.

Regarding the recent statement on the Internet that "the northern strain is more fierce than the south", Zhong Nanshan said that the variant circulating in Beijing is mainly BF.
7, and the variant circulating in Guangzhou is mainly BA.
5.
2, and there is no difference
in essence.
Zhong Nanshan said that in contrast, the incubation period in the north is further shortened, sometimes symptoms appear after the second day of exposure, most people do not have obvious symptoms after infection, and some people have dry throat headache and fever
.
"As long as it does not invade the lungs, it is medically mild
.
"

Some people have pain all over their bodies, high fever, and are very uncomfortable, but this discomfort is different from a serious medical illness
.
He also said that there are also some fevers in Guangzhou that are high and the pain all over the body is obvious
.
The symptoms in Beijing appear obvious, which may be related to the temperature or the escape of the virus
.
"Omicron spreads very quickly, but there can be no such idea that where the strain is stronger and where it is weaker
.
"

Academician Zhong Nanshan also said that many data show that after being infected with Omicron once, the proportion of reinfection within one year is very small
.
He said that after being infected with Omicron, antibodies will be produced in the body, which is equivalent to a vaccination
.

In addition, Taylor was recruited by his family in Guangzhou, had a low-grade fever last night, ate some ibuprofen, and felt better today, which should belong to a mild disease
.

In view of the next step of epidemic prevention and control, Zhong Nanshan suggested that vaccination should continue to be strengthened
.

As for how to vaccinate well, Zhong Nanshan gave some data, you can watch the shot
.
The approximate recommendation is that the first two injections are inactivated, and the third injection is better to change to something else
.
Shanghai's epidemic data from March to June show that vaccines have a significant
protective effect on the elderly.
Compared with unvaccinated people, people over 60 years old who completed booster immunization had a 98.
08% lower risk of death; The risk of death was reduced by 95.
83%
in people over 80 years of age who completed booster immunization.
The effect of heterogeneous vaccine plus (subprotein vaccine/adenovirus vaccine/mRNA vaccine on top of two doses of inactivated vaccine) was significantly improved
.
It is recommended that the Food and Drug Administration accelerate the development and approval of nasal spray and inhalation vaccines
.

Some time ago, Taylor listened to the advice of teacher Zhong Nanshan, after the first two injections
of Sinovac, the third injection was sub-protein.

In the summary, teacher Zhong Nanshan also revealed that his niece (or granddaughter) also had Omicron, but it was fine three days later
.
In addition, he also suggested that everyone should not go to the "morning sun", it is better to stagger.

Finally, Academician Zhong Nanshan thanked these experts
.
