COVID-19 vaccines effective against most SARS-CoV-2 variants: Study

Updated: few hours ago

Washington, Oct 12 (PTI) COVID-19 vaccines by Moderna and Pfizer provide protection against multiple variants of the SARS-CoV-2 virus, including the highly infectious Delta variant, according to a study.

The results come as an increase in so-called "breakthrough" infections caused by the Delta variant among vaccinated individuals continues to raise questions about whether the vaccines offer broad protection against newly arising variants.

The findings, published in the journal Nature on Tuesday, also show that those infected with the virus prior to vaccination exhibit a more robust immune response to all variants than those who were uninfected and fully vaccinated.
