Two doses of Pfizer COVID-19 vaccines only 23% effective against Omicron?
The latest data: Pfizer’s two anti-variant effective rate is only 23%, is the booster useful?
According to the latest research in South Africa, the effectiveness of two doses of Pfizer vaccine is only 22.5%, which is almost impossible to prevent infection. It can only provide the infected person with immunity to prevent aggravation of the disease.
This study analyzed the plasma samples of 12 participants. South African researchers found that compared with the antibody concentration levels in patients infected with the first-generation new coronavirus, the levels of neutralizing antibodies in patients infected with Omicron decreased by about 40 times.
The laboratory’s research director, Alex Sigal, commented on Omicron’s ability to escape the vaccine on Friday, saying that this actually impairs the vaccine’s protection against infection, but it can still prevent severe illness.
It is worth mentioning that after South African researchers just announced that the protective efficacy of two doses of Pfizer vaccine had decreased, a preliminary laboratory study released by Pfizer and BioNTech showed that the third dose of the vaccine can be effective against the Omicron variant virus. Protective effect, while the effectiveness of only two doses of the vaccine is significantly reduced.
US President Biden’s chief medical adviser, Dr. Fauci, also revealed new findings yesterday. Among the 43 Omicron cases infected in the United States in early December, 1/3 of the cases were people who had already received the third booster shot.
According to reports, of the 43 Omicron cases confirmed in the first 8 days of December, 34 were completely vaccinated with two doses and 14 were vaccinated with a booster. Unfortunately, the booster dose does not prevent Omicron infection.
It seems that the fifth wave of the epidemic is on the line and is about to begin.
Although everyone’s life has basically become normal now, you can go to restaurants to eat, you can go to the gym, you can organize gatherings, you can travel, etc.
But perhaps everyone still has a question in their hearts: when will we stop living in fear and let our lives fully return to the ease of 2019?
It seems that this COVID-19 epidemic, which has lasted for nearly two years, now seems to have become a vicious circle that we can never get out of.
The daily increase in confirmed cases has risen sharply again. Sports venues where restrictions have been relaxed have exploded with cluster infections. The immunity generated by the three doses of vaccines cannot stop the breakthrough of the new coronavirus. The mass production of vaccines against the new variant Omicron will take nearly 100%. Days…
In an interview with CBC today, even Dr. Fauci sighed that he did not expect the epidemic to last so long.
Dr. Fauci said that he once thought that the epidemic would not last for such a long time.
“Pandemics are usually characterized by a’big outbreak’ of infection, followed by a decline in cases and a tendency for the epidemic to slowly dissipate.”
“As we see now, many countries, including the United States, have seen three to four surges of infections, which is unprecedented in the history of epidemics.”
The United States has been fighting the epidemic for a year, and now the number of confirmed cases has returned.
According to Fauci, the average daily increase in the number of cases in the United States in the last 7 days (December 6-December 12) has exceeded 120,000.
In the week before December 6, the average daily increase in cases over the seven days was only 85,000.
Moreover, the number of deaths in the United States has exceeded 800,000. This year alone, more than 450,000 Americans have died from the COVID-19 epidemic, which also accounts for 57% of the total deaths in the United States since the beginning of the epidemic.
According to the prediction of the US authorities, the worst possibility is that nearly 2 million Americans will die from this epidemic…
Hope everyone in the world will not be fooled by the peace in the market before Christmas recently, and must warn yourself: The epidemic has never ended.
At ordinary times, pay attention to wearing a mask, maintain social distance, and get the third dose of booster in time for prevention. While protecting yourself, you also protect your family and friends. This is the top priority at present.
