According to the Centers for Disease Control and Prevention, the flu vaccine is the best way to protect people against the flu and prevent its spread. The flu vaccine can also reduce the severity of the flu if a person contracts a strain of the flu that the vaccine did not contain. It takes about two weeks following vaccination for antibodies to protect against the flu.
Some dentists do not routinely prescribe antibiotics and still have successful implant cases. Their success rate may increase with using antibiotics, but may not (it is all a matter of odds). You are likely fine, but may consider a different antibiotic with fewer side effects.
Oral antibiotics have risks. 1  Oral antibiotics are more likely to cause resistant bacteria outside the ear. Then, in the future, the drugs will not work as well. Illnesses will be harder to cure and more costly to treat.  Antibiotic eardrops kill the bacteria faster and more completely than oral antibiotics.
