What would a neutralizing vaccine against ticks look like? And why would it matter that much for a parasite that doesn't usually go from human to human?

The polio vaccination is 4 doses, and a booster every 10 years if you are at risk. Maybe the covid vaccines will fare similarly. Two shots very close to each other isn't ideal for immunisation, we knew that from the beginning.

It would cause tick saliva from causing infection for a lifetime, it matters so you can give a vaccine and not need to upkeep it especially in rural areas. It matters because it will prevent it forever. I think I’m thinking of something that lasts longer, someone mentioned a binding vaccine.

What does at risk of polio mean? I read that polio infections only affect Americans who aren’t vaccinated and touch recently vaccinated baby feces. If you aren’t in that situation you won’t get polio.

As I understand it that's not what neutralizing vaccine means (if it even is well defined). It means you will not get an infection when you are vaccinated, not that being vaccinated will last for a lifetime. This in contrast to leaky vaccines which make you less sick but still allow for infection and transmission. Since this vaccine does not target anything that causes diseases, it's there to make the tick detach, I don't see how neutralizing makes any sense to this vaccine.

Going abroad to places where there is still polio for example. Checked again and apparently it's not a booster every 10 years but once after at least 10 years.
