NEW YORK, Jan. 27 (Xinhua) -- Study so far has proved that the current vaccines remained effective against the variants of the COVID-19, which already infected over 100 million people worldwide, Case Western Reserve University's (CWRU) news portal The Daily on Wednesday quoted an expert as saying.
"Unfortunately, several recent mutations appear to have been beneficial to the virus by increasing its ability to infect us at lower exposures. Fortunately, the vaccine companies have been studying these variants closely and there is no indication yet that these new variants can escape the current vaccines," said Mark Cameron, who has been conducting COVID-19 and other infectious disease research as associate professor at Department of Population and Quantitative Health Sciences, CWRU School of Medicine.
