Have gone through chemo for nonhodgkins lymphoma should i take the flu shot?

Yes: Flu shot has killed virus and will not do any harm unless you are allergic to eggs. Please note that flu shot is not 100% effective even in normal people and your response may be even less, still having said all that, it is important the you take the flu shot. If you have not taken pneumonia vaccination, and shingles vaccine, you should take those also. Wish you good health!
