U.S. and international public health officials say it is imperative that the world’s population get vaccinated against the SARS-CoV-2 virus as soon as possible to slow the development of SARS-CoV-2 variants. Mutations have led to harder-to-fight variants in India where the pandemic is surging and these variants have been identified in other countries. 

The more people who continue to be infected with the pathogen, the more likely the virus will develop mutations that can evade vaccines and treatments, notes Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. 

“Bottom line: We have to get the entire world vaccinated, not just our own country,” Fauci recently told the Journal of the American Medical Association. 

The World Health Organization says that stopping the COVID-19 pandemic will require at least 70% of the world’s 7.8 billion to have immunity to the SARS-CoV-2 virus, which could take until 2023 or longer, given the logistical challenges of getting a vaccine from the manufacturing plant into people’s arms.
