naughtiness! Variant Delta reduced the effectiveness of vaccines to 40% – El Financiero

GENEVA.- The highly contagious Delta variant of covid-19 reduced the effectiveness of vaccines against the disease by 40 percent, said Tedros Adhanom Ghebreyesus, head of the World Health Organization (WHO), urging people to continue wearing face masks and respecting distancing. measures.

“Vaccines save lives, but they do not completely prevent the transmission of Covid-19,” explained Tedros, as the pandemic wreaks havoc in Europe.

Last week, global falls rose 6 percent from the previous seven days, to reach a total of 3.6 million, of which two-thirds (2.4 million) were registered in Europe, the current epicenter of the pandemic, according to data. published by WHO.

“There are data suggesting that prior to the arrival of the Delta variant, vaccines reduced the transmission of the virus by 60 percent, but with its appearance, they dropped to 40 percent,” he said.

The WHO’s expert committee for the analysis of vaccines against covid confirmed that vaccination of children and adolescents can help in the fight against pandemics, but is “less urgent” than immunization of other risk groups.

As children and adolescents are at lower risk of developing severe covid-19, countries should prioritize sharing vaccine doses with the Covax program to bring urgently needed supplies to the poorest countries, the WHO said.

Denis Logunov, deputy director of the Gamaleya Center, which has state funding and created Sputnik V, told Putin that the nasal vaccine is in the testing phase and is being studied “as always, with staff overseeing.”
