Vaccines remain highly effective against COVID-19 virus variants

Doha: Within less than a year of the outbreak of the COVID-19 pandemic, several research teams rose to the challenge and have developed effective vaccines. This year 3.2 billion vaccine doses have already been administered globally, and 37.3 million are now administered each day. 

Indeed, 24 percent of the world population has now received at least one dose of a COVID-19 vaccine. This is already an impressive achievement, but effort is still needed to provide comfort to reduce vaccine hesitancy and ensure that vaccines are available to people in less wealthy countries. Viruses mutate all the time, including the SARS-CoV-2 coronavirus that causes COVID-19. Genetic mutation of a virus is a random process.
