As more parents opt out of vaccinating their kids, many preventable childhood illnesses are making a comeback.
But the medical and biotech communities are already responding.
The influenza virus mutates at the drop of a hat, so some vaccines are more effective than others. But a more permanent solution might be just around the bend.
Humans can still acquire influenza following the flu shot, since the vaccination takes a few weeks to activate. This does not mean Americans should avoid the shot. It is of crucial importance to the more susceptible among us that as many healthy Americans vaccinate as possible.
As the anti-vaccination movement continues to grow, physicians are faced with a dilemma. Should they treat the unvaccinated patients and risk exposing their well patients? Or should they protect those who are unable to be vaccinated from the possibility of disease.
