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.
To prevent endocarditis, patients with certain heart conditions receive a single dose of an antibiotic. You receive it about one hour prior to certain dental treatments. The American Heart Association and American Dental Association now suggest that you receive antibiotics prior to dental treatment only if you have: 1  Had bacterial endocarditis before. 2  A prosthetic (artificial) cardiac valve or prosthetic material used in valve repair. 3  Cardiac valve disease and have had a cardiac transplant.
