It's been known since the beginning what the vaccine does and does not do...

What the vaccine does do:

  • Protect against minor symptoms;

  • Allows you to travel;

What the vaccine does not do:

  • Protect against actually getting the COVID-1984;

  • Prevent infecting others with the COVID-1984 that you have caught anyway;

  • Prevent the worst symptoms, such as death;

what the vaccine does and does not do

"The vaccine". There are sixteen Covid-19 vaccines approved for use around the world, based on four completely distinct biological principles. "The" vaccine doesn't exist.

In the case of the AZ vaccine, it has been obvious since the first Oxford animal trials that that it protects against infection of the lungs and lower respiratory system, and so protects well against the worst forms of Covid pneumonia that is so often deadly. It doesn't protect nearly so well against infection of the upper respiratory tract (nasal passages), and as far as I can tell nobody has made any effort at all to investigate how well it protects against the virus spreading to other organs.

So if you are talking about the AZ vaccine, you have it completely backwards: it has a strong protective effect against the Covid pneumonia that will kill you, but only a weak effect against cold-like symptoms.
