Experts estimate that 10% of the world’s population has anti-nCoV antibodies, while at least 50% of the population is immune to achieve community immunity.
Public immunity can be achieved when at least 50% of the population is immune to nCoV, through exposure or a vaccine, according to a report by the American scientific group. Previously, scientists estimated it would take at least 70% of immune people to be eligible to reach the community immunity threshold.
But these estimates are largely irrelevant and far from tools that experts say are effective in the fight with Covid-19, World Health Organization (WHO) officials stated at a press conference. August 17.
“Right now, on this planet, the global population is still very far from reaching the threshold needed to achieve public immunity, preventing Covid-19 from spreading,” said Dr Mike Ryan, Executive Director of the Level Program. Health studies of WHO states.
“It is important to focus on what can be clearly, intelligently done to prevent the spread of nCoV, instead of hoping that community immunity will save us from a pandemic,” Ryan added.
According to the WHO, one way to increase immunity to nCoV is to survive or be exposed to nCoV, thereby developing antibodies against the virus. However, experts still do not know for sure how strong the anti-nCoV antibodies can last, how effective they vary between individuals.
While nCoV antibodies help protect the body, studies estimate that less than 10% of the world’s population has these antibodies.
“This means that a large proportion of the world’s population can still get Covid-19, and nCoV still has a chance to spread,” said infectious disease epidemiologist Maria Van Kerkhove, head of the Covid-19 specialist group at WHO.
In other words, humans still have a long way to go to achieve public immunity through antibodies. Even when the Covid-19 vaccine is used, it will not be effective for everyone who gets the shot.
“We cannot confuse immunization rates and immunization rates of the population,” said Dr Aylward, WHO Director-General’s Senior Advisor. He suggested setting a higher target for community immunity.
“With half of the world’s population being frozen, the economy in many places stagnates, we need to plan for all levels, no matter how high to achieve public immunity. We don’t want to take risks. We don’t want to make mistakes, “Aylward said.
He also argued that governments and companies responsible for vaccination should not be “put to sleep by the seductive suggestion that the need for public immunity may be low”.
“What people and leaders should do is realize that waiting for community immunity is not a solution ‘to the Covid-19 pandemic,’ says Ryan.
The only solution is to implement all proven strategies such as testing, contact tracking, isolating, masking, interval while continuing to collaborate on a global scale. therapies and vaccines.
