KONTAN.CO.ID – NEW YORK. The following is a summary of some of the latest scientific studies on the novel coronavirus and efforts to find a cure and vaccine for Covid-19, the disease caused by the virus.
The mutation of the coronavirus variant in New York is worrying
A variant of the coronavirus that is on the rise in New York City contains the same E484K mutation seen in variants in Brazil and South Africa. This mutation is believed to make the Covid-19 vaccine and antibody therapy less effective.
Launch Reuters, a report released by New York State Department of Health researchers posted on Monday (1/3/2021) at medRxiv wrote that all variant versions circulating in New York harbor a mutation called D235G that might reduce the efficacy of neutralizing antibodies.
“This variant has increased in the population of the virus circulating in the state of New York nearly 26-fold in less than a month,” the researchers were quoted as saying. Reuters.
The research team added, “The combination of E484K or S477N with the D253G mutation that might cause immune escape, and the increasing number of Covid-19 cases associated with this variant, requires further monitoring,” they said.
Prioritizing the vaccinations of parents
The new study shows that prioritizing the elderly for Covid-19 vaccination not only saves most lives but also saves most years of life.
Reuters reports that taking age and health risks into account, researchers calculated the number of lives the Covid-19 vaccine could potentially save in the United States, Germany and South Korea and multiplied that number by the life expectancy of those vaccinated.
Patients’ risk of dying from Covid-19 increases faster with age – at a rate of about 11% per year – than their remaining life expectancy falls, said study leader Joshua Goldstein of the University of California, Berkeley.
Without vaccination, the number of people who will die from Covid-19 is much higher in the oldest age group than in the younger group. Thus, protecting the older cohort actually saves many more years of life, in total.
“Prior to this study, it was suspected that there were some middle ages – not too old and not too young – who would maximize the benefits of the vaccine, in terms of saving people years,” Goldstein said in a statement.
