For or Against Vaccination?

I would like to know more about the pro's and cons of vaccination.

You read so much about the negatives of vaccination, I'm now confused, as most of the voters on this site seem to be "for" vaccination. I'm reluctant to support the idea, as I there is so much information going around and it's mind boggling.

Also, I'm confused about the question of the survey, does it mean bringing in vaccination as compulsory for all horse owners??

Could someone provide feedback on the following;

• Once vaccination comes in as compulsory, does it mean we will have given up the fight to eradicate EI???
  
• How does the vaccination work in the buffer zones if horses that are vaccinated can still contract EI and pass it along??
  

Will people become complacent once vaccination is in place??
I understand the whole industry needs to get back up and running, but is this going to be at the expense of not completely eradicating EI?
