A recent study conducted by the Centers for Disease Control and Prevention (CDC) has revealed that adults who received the updated COVID-19 vaccine were 54% less likely to contract COVID-19. The newly developed shots, introduced last year, were specifically engineered to provide enhanced protection against the latest variants of the novel coronavirus.
According to the CDC’s study report, “Receipt of the updated COVID-19 vaccine provided approximately 54% increased protection against symptomatic SARS-CoV-2 infection compared with no receipt of the updated vaccine.” The report also emphasized that the new vaccines offer “protection against JN.1 and other circulating lineages” of the virus.
The study, which observed 9,000 individuals tested for COVID-19 at CVS and Walgreens pharmacies from mid-September 2023 to January of the following year, aimed to determine the effectiveness of the new vaccine in preventing infections.
“The recent laboratory data indicate that the updated vaccines generate neutralizing antibodies against emerging XBB lineages and JN.1,” stated the study. JN.1, identified as a new variant of COVID, has gained dominance in recent weeks, as per the CDC’s explanation.
While the study’s findings provide valuable insights, the CDC emphasizes that the results are not conclusive, given the relatively short duration of the study spanning four months. Future studies will delve into assessing the vaccine’s efficacy in preventing severe symptoms and hospitalizations.
“Additional analyses conducted over longer intervals since the authorization of the updated vaccines are necessary for ongoing monitoring of anticipated waning and to determine the effectiveness of vaccines in preventing severe illness,” the report highlighted.
The CDC strongly encourages individuals aged 6 months and older to receive the updated shots for protection against COVID and its evolving variants. Despite the recommendation, recent CDC data indicates low vaccination coverage, with only 22% of U.S. adults and 11% of children having received the new vaccines.
