"Live" viruses give a better immune response. The only reason to use it is if the region you are from has a high prevalence of the disease because it ensures you have lasting immunity. When you get the "dead" vaccine here it cannot reactivate and cause polio, but it is less effective. That being said, we don't need super high resistance to it because it isn't as common here. Essentially, you think of it as:

>Live vaccine prevents 99% of cases but may rarely reactivate actually giving you the disease. The fraction of people this happens to then just fight it off because polio only causes some paralysis in 1:1000 people.

>Dead vaccine prevents 90% of cases but cannot reactivate. This resistance after vaccination does not last as long as the live vaccine.

These numbers are made up, it's been years since I had immunology so I don't remember the exact numbers.

The issue with live vaccines is if everyone isn't getting vaccinated, you are asking for trouble because if someone actually gets the disease, they spread it to everyone who isn't getting vaccinated.

>If US could have mass produced Nukes and used them on Earth without fucking themselves over they would have used them to prevent anyone else from getting nukes in first place.
the whole topic is about space fleet battles
what does the kill potential for nuclear warheads on ICBMs have to do with any of this

it's about space ships killing other space ships, nobody gives a shit how many civilians your nuclear warhead can turn into ash when fired on a planet
way to miss the point holy shit
