As the US prepares for the first round of vaccinations to tackle Covid-19, infectious disease expert Dr. Anthony Fauci called on the public to “be part of the solution” and get vaccinated once it is available. “Say, ‘I’m not going to be one of the people that’s going to be a steppingstone for the virus to go to somebody else. I’m going to be a dead end to the virus,'” Fauci told Facebook CEO Mark Zuckerberg Monday.
