If the effects don't fade too rapidly, new data suggests regular COVID-19 vaccinations could strengthen our immune systems against future variants and even related viruses.
A study by researchers at Washington University School of Medicine in St. Louis has found that repeat vaccination with updated versions of the COVID-19 vaccine promotes the development of antibodies that neutralize a wide range of variants of the virus that causes COVID-19, as well as related coronaviruses.
The COVID-19 pandemic is over, but the virus that caused it is still here, sending thousands of people to the hospital each week and spinning off new variants with depressing regularity. The virus s exceptional ability to change and evade immune defenses has led the World Health Organization (WHO) to recommend annual updates to COVID-19 vaccines.
