1/ I am not an expert on viruses or vaccines, but many people seem confused about what's being said here.

There's a difference between being "infected" (i.e. testing positive for the coronavirus) and having symptoms.

2/ The vaccines appear to prevent you from getting COVID-19 (the disease caused by the virus), but we don't know whether they prevent you from being infected and/or transmitting it to others. You can be "infected" with a virus without showing symptoms.

3/ For instance, you could test positive for human papillomavirus (HPV)—the virus that causes genital warts—and not have warts. Likewise, you may still spread HPV even if you don't have physical warts. And a person you transmit HPV to could develop warts when you never did.

4/ Testing positive for SARS-CoV-2 (the coronavirus) is analogous to testing positive for HPV. Having COVID-19 (the disease sometimes caused by SARS-CoV-2) is analogous to having physical warts (symptoms sometimes caused by HPV).

5/ The vaccine is effective at preventing the disease that can put people in the hospital and sometimes kill them. That's very good. But it may not prevent you from being "infected" with SARS-CoV-2 and passing it to others.

6/ In short:

Testing positive for SARS-CoV-2 ≠ having COVID-19, just like testing positive for HPV ≠ having warts.

I hope that helps clarify what she's saying.
