Is it safe to get the pneumonia vaccine if your sick?

Most recommendations are that you should not take flu vaccinations if you have an active infection with fever or other serious symptoms.

If no fever, and symptoms are mild, you could get the vaccination, but since each case is different, it would be best to speak to your Doctor Who is treating your pneumonia.

You can take the vaccination if you are taking antibiotics, there is no drug interaction problem, but if you still have active pneumonia, ask your doctor's advice about the flu shot. They may suggest that in your case the risk of getting the flu on top of pneumonia at the current stage of your lung infection, would be higher than the risk of an improper immune response to the vaccination and therefore will want you to take the vaccination now.
