COVID expert urges vaccines to stop transmission

As several variants and sub-variants continue to appear, a leading scientist believes the next step is to create a vaccine that stops transmission.

Sir John Bell, who was a member of the UK vaccine task force working on the Oxford/AstraZeneca COVID-19 vaccine, revealed scientists need to focus on stopping the spread as the vaccines currently available have caused massive deaths help prevent.

“We need a new vaccine to stop the transmission, and there are a lot of interesting ideas,” Bell said.

“The deaths from the disease, those really terrible deaths, were largely eliminated by late spring [2021]and they rumbled on, at a very low level and very close to the baseline, and they’ve kept rumbling almost in a flat line ever since.

Bell seemed skeptical about whether current vaccines will have a long-term future, because “none of them are very good at stopping transmissions.”

Instead of focusing on boosters, he thinks scientists should work on ending the possibility of transmission with a new vaccine.

“So you have a few choices. You can make a new vaccine every time you see a variant, and it can be less good than the original vaccine, so you’re chasing your tail,” he explained.

“You could probably use the existing vaccines to sensibly boost the elderly so that they don’t die. We’ll have to wait and see if we see more deaths in that population… but we haven’t seen them yet.”

Bell’s comments come after the World Health Organization (WHO) reported that between January 1, 2020 and December 31, 2021, an estimated 14.9 million people died as a direct or indirect result of Covid-19.

The amount reported was nearly three times what the health authority initially reported. During that period, the WHO reported that 5.4 million people died from COVID-19, meaning 9.5 million people died.

“Excess mortality is the difference between the number of deaths recorded and the number that would be expected without the pandemic,” said Samira Asma, deputy director general for data, analysis and delivery in the Impact Division. whose.

Of the additional deaths from COVID-19, 57% were in men and 82% in people over the age of 60. More than 70% of the additional deaths occurred in the United States, Russia, Mexico, India, South Africa, Peru, Egypt, Brazil, Indonesia and Turkey.
