Ingested vs. Injected

Vaccines are given to people in multiple ways.

They can, depending on the vaccine, be:

  • injected into a muscle (IM)
  • injected under the skin (SQ)
  • sprayed in your nose (intranasal)
  • ingested (oral)

No vaccine is directly injected into the blood stream.

Getting the route correct, especially if a vaccine is supposed to be ingested vs injected is important if you want it to work properly.

The other time you may hear the ingested vs injected issue come up is when someone argues that vaccines are dangerous because you are injecting toxins into a child’s bloodstream.

Of course, this is a poor argument because there are no toxins in vaccines and vaccines aren’t even injected into the bloodstream.
