A WHO scientist says don’t believe the need for a coveted booster shot

GENEVA: As some governments and pharmaceutical officials prepare for coveted booster shots targeting a variety of highly contagious viruses, health officials say it is too early to say whether they will be needed.
“We don’t have the information we need to recommend whether or not we need a booster,” said Somiya Swamyathan, the World Health Organization’s chief scientist, in a zoom interview on Friday. “Science is still evolving.”
Swamyathan said such a call is “premature” as most of the world’s most vulnerable people have not yet completed the first course of vaccination. He said that by the end of this year, the data from countries that have imposed precautionary additional taxes – especially for vulnerable people who may be exempt from SARS Cove II – will be updated by the WHO guidelines.
Cavid booster shots will be introduced in the UK in the fall to avoid another winter surge. Health Secretary Matt Hancock said last month that the world’s first booster study was testing seven different vaccines among volunteers in England.
The UK, which has taxed a larger proportion of the population than any other major economy, has been forced to delay plans to lift restrictions on the corona virus during the restoration of delta-diverse affairs. Has been The first reported strain in India is the most contagious disease ever.
Polishing shots
More transmissible variables, including the beta strain that has emerged in South Africa, require higher anti-antibody levels to prevent infection, leading Pfizer Inc. and Moderna Inc. vaccine makers to test whether they Extended versions of existing shots will provide a wider exception.
A single dose of the vaccine, a variable-directed vaccine from NovoX Inc., may provide substantial protection against beta-strain in people who have been vaccinated against Quaid-19 for the first time, according to a report released this month by the Geitersburg, Maryland-based company and scientists. According to pre-clinical research from the University of Maryland of Medicine.
In a June 11 statement, Gregory M. Glenn, president of research and development at NovoX, said the revised shot also has the potential to provide comprehensive protection against various epidemics.
Frances Collins, director of the National Institutes of Health, said that so far, the US-approved vaccine works significantly better to prevent beta, delta and two other strains.
‘Our future’
“No one is saying you need a booster today,” Collins said in an interview with biologist Lee Hood at the Precision Medicine World Conference on Thursday. “But the booster will be very good at some point in our future, and if other species change here soon, they may come here,” which is not covered by existing vaccines.
At the very least, vaccines will be needed to prevent hospital admissions, ICU admissions and death, according to Paul Afft, director of the Vaccine Education Center at Children’s Hospital of Philadelphia. “With this time, we will probably need a vaccine every three to five years,” he said in a state biotech podcast on Thursday.
Vaccination with immunizations can give some people long-term immunity or fewer side effects, Aft said.
Preliminary data from the UK, Spain and Germany show that the “mix and match” method of using two different types of vaccines causes more pain than two doses of the same vaccine, said Swamyathan of the WHO. , Fever and other minor side effects.
Nevertheless, the so-called heterologous prime boost compounds promote a stronger immune response, resulting in higher levels of both antibodies to the virus and to white blood cells that kill the virus-infected cells. Are
Minister of Science, Technology and Innovation Khairi Jamaluddin said on Wednesday that Malaysia was considering a combination of Aster Zenica and Pfizer biotech shots, where the government would provide immunizations to the population by the end of the year. I’m trying to speed up.
“This concept of controversial primary promotion seems to be working better,” Swamyathan said. “This provides an opportunity for countries that have given people a vaccine and are now waiting for another dose that they have run out of, so that they could potentially use a different platform of vaccine.”
