Delta variant raises fears of new and worsening mutations among unvaccinated

Delta variant raises fears of worsening mutations The rapid spread of the delta variant is raising concerns among scientists that the coronavirus could mutate into more transmissible or deadlier strains. Justine Coleman TheHill

The fresh fears come as the U.S. vaccination rate has largely plateaued and with much of the world still unvaccinated. Such a large number of people without even one vaccine dose gives the virus more chances to spread, replicate and potentially develop mutations. . . 

The World Health Organization has classified four strains as variants of concern that give the virus an advantage: the alpha, beta, gamma and delta variants. Another four strains are labeled as variants of interest, which could possibly benefit the virus.

Officials and experts widely view immediate vaccinations in the U.S. and around the world as the best way to reduce the risk of more harmful variants from developing.
