Medicine & TechnologyTwo new studies recently presented a possible explanation why newer COVID-19 variants like the Alpha and Delta variants are extremely infectious, affecting far more people compared to the original virus.
New estimates from researchers recently showed that COVID-19 vaccines were able to save hundreds of thousands of lives and preempted over a million hospital admissions in the United States.
Experts say it's no longer surprising that new variants have already emerged in the US. However, they emphasize that the unchecked transmission of the virus offers abundant opportunities for it to mutate.
