COVID-19 Vaccines May Be Less Effective On Some Variants of Coronavirus. Variant viruses are surging in America and scientists are conduction studies on that. Now they found that the existing vaccine may not show effectiveness against them. The virus variant was first detected in South Africa. The World Health Organization had already said that the emergence of new variants of the virus has raised questions about whether or not existing vaccines will work. Now, three new Coronavirus mutations were recently found in the USA. even though researchers suggest that vaccines are less effective against them, local experts advise that still, vaccination against COVID-19 is important.
COVID-19 Vaccines May Be Less Effective On Some Variants
The manufacturers of vaccines, Pfizer and Moderna vaccines reported that their vaccines are effective against the Coronavirus variant found in the United Kingdom. But these vaccines are less effective against the highly transmissible variants found in South Africa and Brazil. Dr. Todd Vento, an infectious disease physician at Intermountain Healthcare said, “the two vaccines are mRNA created. The folks who have had the vaccine and when they have tested against those virus strains, they saw lower, tighter, neutralizing antibodies. So, less effective than the earlier strains, but still a level that would get you immunity.”
Fauci had already warned that virus variants are a ‘wake-up call’
In January 2021, one day after a new variant was identified in the USA, Dr. Anthony Fauci said that the emergence and increasing spread of coronavirus mutations mean that vaccine makers must be ready to make new shots to stay ahead of the public health crisis.
The researchers have tested the U.K. strain against the vaccine and it creates neutralizing antibodies. When tested against the Brazilian and South African strains against the vaccines, it differs from other. Even though the reports suggest that the vaccines are less efficient, local infectious disease experts say that there is more to it than that.
“We have to look at that data and say. 72% against symptomatic COVID, but higher percent effectiveness against having COVID that will put you in the hospital or risk your death. We should absolutely get the vaccine because they have been shown to prevent symptomatic COVID, severe COVID, hospitalizations from COVID, and that’s what we still want”, says Dr. Todd Vento.
The associate professor at the University of Utah Health Division of Infectious Diseases says, “It does seem to blunt the severity of disease and prevent infection-which I think we need to recognize as a really important goal of COVID”.
Experts said that in the years to come, a booster shot may be needed. Thus the vaccine companies, Pfizer and Moderna reported that they will begin research on testing booster shots to enhance your immune response against the variants of Coronavirus.
