Should vaccinated people mask up with COVID-19 cases rising? It depends on your situation, but masking in public can provide another layer of protection and help prevent the virus from spreading to others who aren’t protected.
An easing of safety precautions and the large number of people who remain unvaccinated in many regions are contributing to the spread of cases around the world.
美國疾病管制暨預防中心 (The U.S. Centers for Disease Control and Prevention, CDC) 先前建議，民眾若是已經完整接種疫苗，大多時候外出得以不配戴口罩，目前該機關仍持相同立場。
The U.S. Centers for Disease Control and Prevention has not changed its advice that fully vaccinated people can safely go without masks in most situations.
But Dr. Rochelle Walensky, the agency’s director, said local decisions on mask mandates could vary depending on vaccination levels and whether there’s a surge.
Los Angeles County recently started requiring residents to wear masks indoors regardless of vaccination status, for example, and officials in New Orleans are urging people to do the same.
Though COVID-19 vaccines greatly reduce the chance of severe illness and death and remain effective against variants, some experts said wearing a mask is a reasonable precaution since it’s still possible to get infected.
Masking could also help prevent the spread of the virus to children too young for vaccination and people with weak immune systems.
薩斯卡徹温大學 (University of Saskatchewan)疫苗與傳染病組織的病毒研究員Angela Rasmussen表示：「我自己出門到公共場合依然配戴口罩，除了保護自己，也是為了整個社區著想。」
“Personally, I continue to wear a mask when going into public spaces outside of my household, both for my own protection and for the sake of my community,” said virus researcher Angela Rasmussen of the Vaccine and Infectious Disease Organization at the University of Saskatchewan.
范德堡大學 (Vanderbilt University) 傳染病專家William Schaffner博士則是指出：「高齡者或是體質較弱的人，一旦感染病毒便容易引發重症，對於他們來說，『多重保護』才是合適的方法。」
Dr. William Schaffner, an infectious disease expert at Vanderbilt University, said a “belt-and-suspenders” approach also makes sense for people who are older or have health issues and are more vulnerable to getting severely ill if infected.
“I’m pretty healthy, but I do have gray hair. So when I go out to the supermarket, I’m masked,” Schaffner said.
