Question

are antibiotic effective against viruses cold and flu​

Answer 1

Answer:

Antibiotics are medications that fight infections caused by bacteria, but the flu is cause by a virus.  

Taking antibiotics when you have a virus may do more harm than good. Taking antibiotics when they are not needed increases your risk of getting an infection later that may resist antibiotic treatment.

Antibiotics don't work against infections caused by viruses, such as colds and flu. So there's no point taking antibiotics to treat a cold or flu.
