Can a flu vaccine give you flu?
No, flu vaccines cannot cause flu illness. Flu vaccines given with a needle (i.e., flu shots) are made with either inactivated (killed) viruses, or with only a single protein from the flu virus. The nasal spray vaccine contains live viruses that are attenuated (weakened) so that they will not cause illness.
Are any of the available flu vaccines recommended over the others?
What if a preferentially recommended flu vaccine is not available?
Is it better to get sick with flu than to get a flu vaccine?
No. Flu can be a serious disease, particularly among young children, older adults, and people with certain chronic health conditions, such as asthma, heart disease or diabetes. Any flu infection can carry a risk of serious complications, hospitalization or death, even among otherwise healthy children and adults. Therefore, getting vaccinated is a safer choice than risking illness to obtain immune protection.

Oct 22, 2020 · While flu and the common cold can have similar symptoms, they are caused by different viruses. And they each possess distinct symptoms, too. Cold, for instance, may give you a runny or stuffy nose; influenza usually doesn't.
