Do current COVID-19 vaccines also protect against the mutated variants of the virus?

Scientists suspect so. Viruses mutate constantly. Mutating means that the genetic material in the virus changes. These changes do not necessarily affect the effectiveness of the vaccines against the virus. Some vaccines remain effective for many years after their development and provide long-term protection, while other virus strains (such as seasonal flu) change so frequently and to such an extent that the composition of a vaccine must be updated annually in order to be effective. The COVID-19 virus changes constantly (although more slowly than the seasonal flu virus). The changes in the COVID-19 virus will be strictly monitored. If it appears that a COVID-19 vaccine is less effective against a new variant, the vaccine will be adjusted.
