No, antibiotics do not work against viruses, but they work on bacteria.
COVID-19 is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment. However, if you are hospitalized for the COVID-19, you may receive antibiotics because a concurrent bacterial infection is possible whilst having COVID-19.
不，抗生素对病毒无效，但对细菌有效。
COVID-19是一种病毒，因此，不应将抗生素用作预防或治疗手段。然而，如果你因为COVID-19而住院，你可能会接受抗生素治疗，因为同时感染细菌是可能的。

COVID-19 Advice for the General Public
Vaccines against certain pneumonias, such as influenza, pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus. However, these vaccines are important especially if you have some medical conditions that would make you vulnerable to these infections (e.g. elderly, immunocompromised patients, or some patients with certain lung or heart conditions). We are glad that some of these vaccines are covered by MOH’s National Adult Immunisation Schedule (NAIS), and you can discuss with your primary care doctor to learn more.
