Covid Vaccine News: Pfizer Moderna Vaccine Affects Indian Covid Virus: Study |

WASHINGTON: The Pfizer and Moderna Covid vaccines are likely to remain highly effective against the first two strains of the coronavirus first discovered in India, according to new research by US scientists.
The laboratory study was conducted by the NYU Grossman School of Medicine and NYU Langone Center and was considered preliminary as it has not been published in a peer-reviewed journal.
“What we found was that the vaccine’s antibodies were slightly weaker compared to the strains. But it’s not enough that we think it will have a profound effect on the vaccine’s protective ability, “senior author Nathaniel” Ned “Landau told AFP Monday.
The researchers received blood from people who had been vaccinated with one of two shots of the vaccine, which are distinguished in the United States and given to more than 1
50 million Americans.
They then revealed these samples in a lab to look for engineered pseudovirus particles that have mutated in the corona virus’s “obstructed” area, particularly for strains B.1.617 or B. 1.618 which was first seen in India.
The mixture was eventually exposed to lab-grown cells to see how many infections it could infect.
Engineered pseudovirus particles contain an enzyme called luciferase, which the firefly uses to set fire.Adding it to the pseudovirus makes it possible to determine the number of infected cells by measuring light.
Overall, for B.1.617, they found that the amount of neutralizing antibodies was almost four times lower – the Y-shaped protein the immune system produces to stop pathogens from invading cells for B.1.618 was about three times lower.
In other words, some antibodies are now no longer viable compared to this strain. But you still have a lot of antibodies that work with this strain, ”said Goop.
“There is enough work we believe the vaccine is highly protective,” he added, because overall levels are still higher than those found in samples taken from people recovering from previously uninfected viral infections.
But laboratory investigations like this cannot predict what real-world performance will be, which will have to be validated through other studies.
The corona virus is known to bind to a specific receptor in human cells called ACE2, which is used to force it in.
The Landau team showed that the Indian species can bind tighter to this receptor, as well as other species of concern.This may be linked with increased transmission capacity compared to the line. Original
“Our results ensure that the current vaccine will provide protection against the strains identified to date,” the team concludes.
However, they do not exclude the possibility of new, more vaccine-resistant strains, highlighting the importance of widespread vaccination on a global scale.
