The finalists in this year's Boston mayoral election continue to push all eligible city residents to be vaccinated against COVID-19.City councilors Annissa Essaibi George and Michelle Wu, who will compete in the Nov. 2 municipal election, also approve of booster shots for seniors and those at high risk.The turnout was not high for a vaccination clinic that was held in Boston's Roxbury neighborhood on Saturday, which was "Vaccine Day" in the city."We have the tools to end it, but we need to close gaps in vaccination and require protections for our workers and community members, especially as we're getting into the colder months," Wu said."We've got to get vaccines into the arm's of our city's people across the board," Essaibi George said.However, Essaibi George and Wu do have some differences of opinion when it comes to potentially enacting further restrictions.Wu was praised by her supporters for being tough on former Boston Mayor Marty Walsh for not going far enough when it came to city lockdowns.Essaibi George, meanwhile, is wary of a coronavirus-related shutdown in the future."We've got to take every measure and every precaution to not go back into another lockdown," Essaibi George said. "We've seen how devastating that's been, certainly, for our city's residents, for our business owners and for our kids, our young people.""If we take action now -- if we really get everyone vaccinated, make sure the protections are in place so that we are not increasing the spread of the virus -- we can end this pandemic and move on, and not have to face those tough decisions," Wu said.The city councilors were the top two vote-getters in Tuesday's mayoral preliminary election.Essaibi George spent Saturday meeting with supporters in Boston's Chinatown neighborhood.Wu received an endorsement from State Sen. Sonia Chang-Diaz, a 2022 Massachusetts gubernatorial candidate, during a campaign event at Villa Victoria in the South End.
