It's valid if your opinion of the word "valid" is the opposite of what everyone else thinks it means.

Until recently we didn't vaccinate children under 12, we still don't vaccinate children under 5. I'm sure there are other groups of people we will never vaccinate. Therefore it's not completely bonkers to believe that you personally don't need the vaccine because you're in a very special group of people while also believing that almost everybody should get vaccinated.

The fact that health authorities have not been vaccinating young children on the basis of the data we do have has made some contribution to the fact that young children haven't had reactions to it.

I don't know the statistics and generally believe that everybody should probably get the shot, I just wanted to point out that it's not a lunatic position to simultaneously believe that the vaccine is good and refuse to take it because you yourself might be in a group where the risk of an infection is lower than the risk of the vaccine.
