#Current affairs hot headlines say #Pfizer and Moderna want to harvest again: the new vaccine is effective against the new crown variant virus BA.2.86? Does anyone else believe it?
The two ruthless characters of Pfizer and Moderna came out again, and said how their new vaccine was useful.
Pharmaceutical companies Pfizer and Moderna said on September 6 that their updated COVID-19 vaccines have a strong response to the highly mutated Omicron BA.2.86 variant of the new coronavirus, or may be effective against it.
Moderna said that human clinical trials have found that compared with untreated natural antibody responses, the neutralizing antibodies against BA.2.86 increased by 8.7 times after injection of the updated vaccine.
Pfizer said that preclinical experiments using mice found that the new vaccine produced a strong antibody response to BA.2.86.
The new crown vaccine, once known as the "Pfizer vaccine", later appeared under the trade name "Fubitai". It was developed by the American pharmaceutical company Pfizer in collaboration with the German company BioNTech.
Both the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) are tracking a highly mutant variant of the novel coronavirus (SARS-CoV-2) called BA.2.86. It has invaded eight countries, including the United Kingdom, the United States and Canada, in recent weeks, and has appeared in human and/or wastewater samples, which has attracted attention from all walks of life.
Reuters quoted several experts on the 7th as saying that due to mass vaccination and the establishment of immune defenses worldwide by previous infections, BA.2.86 is unlikely to cause a serious epidemic or death wave.
A highly mutant SARS-CoV-2 variant called BA.2.86 has appeared in human and wastewater samples from the United States, Canada and the United Kingdom in recent weeks, attracting international attention.
The variant, nicknamed Pirola on social media (a combination of the Greek letters Pi and Rho), has undergone a large number of mutations compared to the previous Omicron subvariant, and some scientists are wary of it.
The U.S. Centers for Disease Control and Prevention (CDC) issued an update on August 30, saying that although BA.2.86 currently causes only a small number of infections, it is worth noting that it has multiple genetic variants and has been detected in multiple places in a short period of time.
The World Health Organization (WHO) listed BA.2.86 as a "variant under surveillance" on August 17 because "a large number of variants have been detected".
Some people are worried that experts warn of two major side effects
mRNA vaccines such as Pfizer's BNT vaccine and Moderna vaccine can cause side effects such as myocarditis and pericarditis, and people have died in the past. According to the European Medicines Agency (EMA) safety commissioner, such side effects mainly occur within 14 days of vaccination.
Fear of myocarditis, side effects of Guillain-Barré syndrome
Including Gruber and Deputy Director Crowther of the FDA's Office of Vaccine Research and Review, and a number of scientists from the World Health Organization (WHO) believe that there is no need for more booster shots for the general population, and there are more and more signs that the protection of the new crown vaccine is significantly weakened 4 to 6 months after the completion of vaccination.
Dr. Gruber and Dr. Crowther led the FDA's Office of Vaccines and oversaw vaccines for decades, and the article published in The Stabb is not based on the FDA's position. According to the New York Times, they disagree with the Biden administration's previous hasty decision to push for vaccines.
The U.S. Army Research Institute's Virology Department Laboratory noted that this hasty decision to administer vaccines has lessons in the past. For example, in the Gulf War, in order to prevent terrorist organizations from using anthrax as a biological weapon, the United States urgently developed an anthrax vaccine for the US military to administer, and as a result, these vaccinated soldiers successively developed symptoms of multi-organ confusion, known as the "Gulf War syndrome".
Moderna reportedly said its vaccine increased the number of neutralizing antibodies against BA.2.86 by 8.7 times, and the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) are tracking BA.2.86.
Jacqueline Miller, head of Moderna's infectious disease division, said in an interview: "We think this is what people want to hear when they prepare to go out in the fall. She added that the data should also help reassure regulators.
Despite the blockbuster news of the launch of the new vaccine, the shares of Pfizer and Moderna still fell during the trading session, and investors also saw through?
It should be noted that yesterday, September 6, the Moderna Omicron subvariant bivalent booster vaccine was launched in Hong Kong.
