What are the details about the vaccine for the Omicron strain of corona? And who is the president who announced that he was infected with Corona for the second time? How long do Omicron symptoms last? The answers are in this report.
Who is working on the new vaccine against the Omicron strain?
The American company Pfizer.
When will human trials of the Omicron vaccine begin?
The US company Pfizer plans to begin human trials of its new Omicron vaccine before the end of January, according to a Business Insider report.
When will the Omicron vaccine be ready?
Michael Dolsten, chief scientist at Pfizer, told Business Insider that the vaccine would be ready by late March.
It is unclear whether the new vaccine is needed or will be used, and Dolstein said the current vaccine still works against the Omicron strain.
The new clinical trial schedule for an updated dose comes with the omicron variant spreading worldwide and causing an increase in infections.
“This vaccine will be ready in March,” Pfizer CEO Albert Burla told CNBC on Monday morning. “I don’t know if we’ll need it, I don’t know if it will be used, but it will be ready.” “.
A Pfizer spokesperson said details of this new research were still being worked out with regulators, including how many volunteers would be registered and which countries the trials would be conducted in.
Do current vaccines protect against Omicron?
Dolstein said that the current vaccine – developed by Pfizer and German biotech company BioNTech – still provides “really strong hospitalization protection” against the omicron variant, but current doses are less effective in stopping less severe disease.
Dolstin added that an updated version of the vaccine may address this decline.
Are other companies working on an Omicron vaccine?
Stefan Bancel, General Manager of Moderna, said that the company’s laboratory is preparing an additional dose of the mutant Omicron that will be ready in the fall, noting that clinical trials will begin soon, according to the French press agency.
In a statement to CNBC, Bancel said, “We are currently discussing with health officials around the world in order to make a decision on what we believe is the best strategy to give an additional dose in the fall of 2022.”
He stressed the importance of maintaining the progress that has been made in confronting the virus, warning of the danger of losing this progress.
Who is the president who announced that he was infected with Corona for the second time?
Mexican President Andres Manuel Lopez Obrador announced yesterday, Monday, that he had contracted Covid-19 for the second time, assuring his citizens that he was suffering from mild symptoms.
“I am informing you that I have COVID-19, and although my symptoms are mild, I will remain in isolation and will only do office work, and will communicate via virtual space,” the president wrote in a tweet on Twitter.
And Lopez Obrador, 68, rarely wears a muzzle, and he appeared ill on Monday morning during his daily press conference, as he spoke in a hoarse voice, stressing that he intends to conduct a Covid-19 examination despite his belief that he only had influenza.
The Mexican president was infected with the Corona virus in January 2021, and the symptoms of the disease at that time were also mild.
Lopez Obrador received the AstraZeneca vaccine last year, as well as a booster dose on December 7.
How long do symptoms of mutant omicron last?
Symptoms of Omicron or any other Covid-19 mutant vary from person to person, and factors such as vaccination status, health history, age and lifestyle play a role in the duration and severity of the disease, according to a report by Derek Hawkins for The Washington Post. American.
The author stated that the perception arising from the Omicron mutant indicates that it may be less likely to cause hospitalization for those infected with it compared to the Delta mutant.
Some preliminary data indicate that Omicron infection may be less severe and have cold or flu-like symptoms in some patients.
A Norwegian study described an outbreak of the Omicron mutant at a party held on November 30, attended by 117 fully vaccinated people, of whom 66 tested positive for the virus, compared to 15 suspected of being infected.
Health authorities who investigated the outbreak found that coughing, nasal congestion, fatigue and sore throat were the most common symptoms among those infected, followed by headache and fever.
More than a dozen of those infected said symptoms disappeared within two days, while 62 attendees said they experienced some symptoms for one week.
The researchers found that none of the injuries required hospitalization until December 13, two weeks after the party.
Research shows that people with an average degree of infection with the Covid-19 virus – whatever the strain – have a lower risk of transmitting the infection to others 10 days after the onset of symptoms, provided that their symptoms have improved by that time and they have not developed a fever.
On the other hand, severe cases of infection can extend for more than a month, which means that the period of infection is longer, and in this case there is a “long-term Covid-19” problem, which can cause some symptoms to persist for several months even if the person pollinator.
And according to Joshua Septimus, medical director at Houston Methodist Health Care, some symptoms of the Corona virus may also last longer than others.
“In particular, fatigue and loss of taste and smell can persist beyond the period of infection,” Septimus wrote recently.
The author said that the best way to reduce the severity of the disease and reduce your risk of developing it for a long time is by getting a vaccination and a booster dose. According to a growing body of research, healthy people who receive a booster dose of the vaccine are less likely to become seriously ill or end up in the hospital.
He added that it appears that people who received the initial doses of vaccination without receiving the booster dose are also protected from severe disease as a result of this virus, while unvaccinated people and those with special health conditions have an increased risk of severe disease as a result of the Covid-19 virus, the possibility of hospitalization and death.
