Pfizer CEO: A new crown vaccine may be launched before the end of March.
On January 11, Pfizer CEO Albert Bourla said that the company expects to need a redesigned new crown vaccine to specifically respond to the outbreak.
Mikron strain, Pfizer should be able to launch this vaccine by the end of March
.
"I think that's the most likely scenario, " Able told JPMorgan's annual healthcare conference on Monday (January 10), according to Reuters
.
He revealed that Pfizer and its German partner BioNTech are developing a special A vaccine against Omikron, and a vaccine that contains ingredients from an older version of the vaccine but also works against Omikron
.
"We're looking at higher doses, we're looking at different timelines
.
We're doing a lot of things right now ," Able said
.
He said Pfizer could apply to U.
S.
regulators as soon as March for a redesigned vaccine.

Henan faced Delta and Omicron at the same time.
The Office of the New Coronary Pneumonia Epidemic Prevention and Control Headquarters in Anyang City, Henan Province urgently reminded on the 10th that 2 cases of nucleic acid test positive people found in the local screening on the 8th were tested by the Henan Provincial Center for Disease Control and Prevention.
Whole-genome sequencing of the room virus showed that the two infected viruses belonged to the BA.
1 branch of the Omicron variant.
After analysis and comparison, they belonged to the same transmission chain as the existing local epidemic in Jinnan District, Tianjin
.
At present, Henan is facing both Delta and Omicron at the same time
.
Since December 31, 2021, Henan Luoyang, Xuchang, Zhengzhou, Zhoukou, Shangqiu, Xinyang, Anyang and other places have successively found positive cases of new coronary pneumonia
.
According to data from the Henan Provincial Health and Health Commission, as of January 9, a total of 289 local confirmed cases have been reported in this round of epidemic in Henan
.
Zhang Ruoshi, member of the party group and deputy director of the Henan Provincial Health and Health Commission, reported at a press conference on the 9th that there were clustered epidemics in Zhengzhou and Xuchang.
The sequence homology is high, and the virus gene sequence is Delta strain
.
As of January 9, 160 cases have been diagnosed in Xuchang, 92 in Zhengzhou, and 16 in Anyang
.
Combined with the results of epidemiological investigation and gene sequencing, Anyang City basically identified the source of infection for this outbreak as a college student who returned to Tangyin County, Anyang City from Jinnan District, Tianjin City on December 28, 2021
.
However, the source of the virus in Zhengzhou and Xuchang is still unclear, and the prevention and control situation is severe and complicated

The hospitalization rate of new crowns in children in the United States hit a new high.
Doctors talk about "children are more susceptible to infection with Omicron": it may be related to the susceptibility of infants and young children.
According to the latest data released by the US Centers for Disease Control and Prevention (CDC) The number of children under the age of 5 hospitalized with coronavirus has risen sharply, reaching the highest level since the outbreak began
.
As of January 1, 2022, 4 out of every 100,000 hospital admissions in the U.
S.
for children 4 and younger were infected with COVID-19, double the rate a month earlier and triple the rate at the same time last year around
.
For every 100,000 children aged 5 to 11 admitted to hospital, only 0.
6 were infected with the new coronavirus, and this rate has not changed significantly from the past
.
According to the American Academy of Pediatrics, in the week ended December 30 last year, more than 320,000 cases of children infected with the new crown were reported in the United States, an increase of 64% compared with the 199,000 confirmed cases in children reported in the previous week.
twice as much as the previous two weeks
.
In addition, China recently "confronted" Omicron head-on for the first time
.
Zhang Boli, an academician of the Chinese Academy of Engineering, said in an interview with the media on January 9 that one of the manifestations of the Tianjin epidemic is that the proportion of young infected groups is high, which is also a new feature of the Ormicron strain, which deserves a high degree of vigilance and response
.
Foreign media reports and analysis pointed out that one of the reasons for the increase in the rate of hospital admissions for children 4 years and younger due to infection with the new crown is that children 4 years and younger in the United States cannot be vaccinated
.
It is reported that the CDC has not yet approved the vaccine for children under the age of 5
.
Previously, World Health Organization officials had stated that more evidence showed that the Omicron strain mainly stays in the upper respiratory tract of the human body, so it is more likely to cause upper respiratory tract infection in the human body
.
Dr.
Christine Oliver, a pediatrician from New York, believes that young children have shallow airways, so they are more susceptible to upper respiratory tract infections and are more susceptible to the Omicron strain
.
"The disease that affects the upper respiratory tract is more likely to affect young children," she said
.
U.
S.
federal health officials have also expressed concern, arguing that the Omicron strain is more likely to be more common in children than in older children Children 4 years and younger will be "less gentle"
.
However, some doctors said that compared with adults, children infected with Omicron are still at a much lower risk of severe illness
.
Dr.
Rochelle Valensky, director of the US CDC, also said at the press conference that there is currently no signal that the Omicron strain will pose a huge threat to young children
.
Children infected with the Omicron strain may develop another condition: roaring
.
It is reported that this is an inflammation and edema of the larynx, trachea and bronchi caused by influenza virus.
The main symptoms are difficulty breathing and a low-pitched cough similar to a seal.
Infants and young children are the main infected people.
.
"Children's airways are so narrow that they are susceptible to inflammation, which can lead to swelling of the upper airway and strange coughing noises , "
explained Dr.
Buddy Creech, a pediatric infectious disease specialist at a Tennessee Medical Center .
And his colleagues noticed that many of the children infected with Omicron developed this cough .

The number of infections in India hit a new high.
India's newly confirmed cases exceeded 161,505 on January 8, reaching the highest level since the end of May last year .
But even as the epidemic is so severe, many people are still participating in rallies of up to tens of thousands of people without wearing masks .
At present, parts of India have begun to close swimming pools, gyms, schools and other places .

Vaccination with the third dose of vaccine can actively respond to Omicron.
Recently, the world's authoritative academic journal "Cell" published two consecutive studies on the antibody against the mutant of Omicron.
Both papers pointed out that the third Positive effects of vaccines against Omicron variants .
Stefan Pöhlmann's team from the Georg-August-University Göttingen and the German Primate Center published a paper in the Cell Press journal Cell entitled "The Omicron variant is New research on highly resistant against antibody-mediated neutralization –implications for control of the COVID-19 pandemic” . The study pointed out that the new coronavirus Omicron variant is resistant to several therapeutic antibodies and can effectively escape antibodies induced by previous infection or two doses of the Pfizer vaccine (BNT162b2)
.
In contrast, the antibodies induced by three doses of Pfizer vaccine or mixed vaccination with Oxford-AstraZeneca/Pfizer vaccine (ChAdOx1/BNT162b2) were more effective in neutralizing the Omicron variant
.
Alejandro B.
Balazs' team from the Ragon Institute of MGH, MIT, Harvard, Massachusetts General Hospital, MIT, and Harvard published a paper in the Cell Press journal Cell titled " mRNA-based COVID-19 vaccine boosters induce neutralizing immunity against SARS-CoV-2 Omicron variant new research
.
The study reported that the Omicron variant was able to escape vaccine-induced humoral immunity, but the third dose of mRNA vaccine-induced humoral immunity was able to cross-neutralize the virus
.
In addition, pseudoviruses with Omicron spikes showed more efficient transduction of ACE2-expressing target cells than other strains
