Pfizer recently predicted that the COVID-19 pandemic will continue to last for one to two years in some parts of the world, and may fall to “endemic pandemic” (Endemic) levels in others during the same period.By 2024, the novel coronavirus is expected to be controlled globally, and will become a normal epidemic in some regions.

Public health experts and scientists around the world have revised their expectations for 2022 as the global spread of the omicron variant of the novel coronavirus brings great uncertainty to the epidemic.

Pfizer recently predicted that the “Pandemic” will continue in some parts of the world for one to two years, and could fall to “Endemic” levels in other parts of the world during the same period. By 2024, the Novel Coronavirus is expected to be controlled globally and become a regular epidemic in certain regions.

“This winter and the Spring Festival we will spend the last winter of the epidemic response together with the international community,” said Zhang Wenhong, director of the department of Infectious Diseases at Huashan Hospital affiliated to Fudan University. He explained to China Business News that once the global epidemic becomes normal, it will slowly enter the “epidemic” stage. The term ‘Endemic’ refers to a Endemic epidemic in a region, such as malaria, which is Endemic in parts of Africa.

MiKael Dlosten, Chief scientist at Pfizer, said: “The exact timing of [EMBRYONIC] remains dependent on the development of the disease, the effective deployment of vaccines and related therapies, and equitable global distribution of vaccines. The emergence of new variants can also affect the duration of the Pandemic.”

Just a few weeks ago, infectious disease experts were predicting that countries could begin to emerge from a “pandemic” in 2022 after novel Coronavirus variants such as Delta, with places with high vaccination rates ending outbreaks first. But the emergence of Omicron could significantly increase the rate of reinfection, undermining scientists’ optimistic hopes.

The latest study, from Imperial College London, found that the infection rate was 5.4 times higher with the Omicron variant than with Delta, and said there was no indication that it was less virulent than Delta.

There has been a sharp rise in the number of omicron cases in the UK in recent weeks. On Friday, the number of cases in the country rose by more than 93,000 in a single day, setting a new record. The number of omicron infections rose from 1,961 to 3,201 in 24 hours.

Although Omicron is able to evade the immune response caused by the vaccine, these studies also show that the booster remains effective against severe disease caused by Novel coronavirus infection. The data showed that the two-dose vaccine was less than 20 percent effective against Omicron, while the booster was between 55 and 80 percent effective against Omicron. This also means that a booster vaccine is urgently needed.

Pfizer and its partner BioNTech are expected to produce 4 billion doses of COVID-19 vaccine next year, generating $31 billion in revenue. The latest clinical data show that Pfizer’s pending COVID-19 oral antiviral is nearly 90% effective against severe COVID-19 disease.

In response to Omicron, some countries have reverted to measures taken earlier in the pandemic, including travel restrictions, requiring masks and social distancing, and cancelling holidays for large parties.

Experts also warn that even after the future coronavirus becomes “Endemic”, the new mutations could trigger regional outbreaks and a surge in seasonal infections in the coming years. “There will always be a baseline case of COVID-19 infection, hospitalization and death, but many people have not accepted that,” said Amesh Adalja, an infectious disease specialist at Johns Hopkins University’s Center for Health Security.
