70% of the vaccination target must be met to defend against Omicron: WHO-Global Issues

This development is as a high-level World Health Organization (Who) Epidemiologists reiterated the agency’s message that countries cannot “strengthen” the way out of the pandemic, and the spread of the Omicron variant is so “strong”, just as the Delta variant did.


“In the context of intense social integration, in the context of limited use of proven public health measures, in the context of limited global vaccination coverage… these are the conditions that allow any variant and any virus to flourish. “Dr. Maria Van Kerkhove told BBC Radio. “Omicron is taking advantage of this, and so is Delta.”

The WHO stated that before the holiday, 128 countries reported at regular press conferences in Geneva that they had identified Omicron.


Dr. Abdi Mahamud, a WHO epidemiologist, told reporters that there is still not enough data to tell whether the Omicron variant is more serious than other variants coronavirus Strains.

He pointed out that in London, the number of infections has been “severely hit” by the surge in infections. Coronavirus disease Infection, the current hospitalization rate is about 20% lower than in 2020 before vaccination.


“So the main message is that if you are vaccinated, you will be protected, but if you are fragile or not vaccinated, this kind of Omicron-whether it is mild or mild to other people-it can cause serious damage to you. Big blow,” he said. “So, vaccination (yes) is very critical.”

WHO epidemiologists pointed out that more and more studies seem to indicate that Omicron variants seem to mainly affect the upper respiratory tract, resulting in milder symptoms.

He said that other strains can affect the lungs and may cause severe pneumonia, but further research is needed to prove Omicron’s assessment.


“The challenge is not the vaccine, but the vaccination of the most vulnerable people,” he said, before urging more countries to promote 70% vaccine coverage as soon as possible.

Without this level of vaccine protection, the virus would “replicate in an overcrowded, unventilated, and unvaccinated environment,” Dr. Mahamud continued, describing these types of environments as ideal places for COVID-19 mutation.

He said: “We saw it in Beta, we saw it in Delta, we saw it in Omicron, so it is in the global interest to vaccinate 70% of the country’s population to reduce the impact of this mutation.”

Fair sharing

The WHO’s call for vaccine fairness is not new, as many wealthy countries are considering providing their people with a fourth coronavirus vaccine.

Before Christmas, WHO Director-General Ghebreyesus warn The “strengthening package” may “provide more opportunities for the virus to spread and mutate by shifting supplies to countries that already have high levels of vaccination coverage,” thereby prolonging the pandemic.

The head of WHO emphasized that the priority must be to support countries to vaccinate 40% of their population as soon as possible, and to vaccinate 70% of the population by mid-2022.
