Methane is a potent greenhouse gas, 20 times more powerful than carbon dioxide at trapping heat. New Zealand scientists have developed a vaccine to cut down on livestock flatulence, which should help farmers avoid a proposed “flatulence tax” on the methane their livestock produces.

Any proof for your wild accusations?

Average life spans have been increasing and there is a direct correlation between advances in vaccine technology and average lifespan. Yet some claim that they are killing us, causing autism, and making chickens moonwalk. OK, I made the last one up. And none of these clams have been proven. But if these fringe elements actually manage to convince enough people to stop vaccinating their kids, its likely that not only will their kids suffer and die (seems like abuse to me), but my kids could get sick too. And me. And you.
I enjoy lunatic fringe theories as much and the next paranoid conspiracy theorist. And maybe the little green men were on the grassy knoll and the commies are sapping our precious bodily fluids with fluorinated water, and we really do have a mineshaft gap, but if you are going to make choice based on outrageous and unproven claims against science, I'd prefer if you made choice that just kill you and not the rest of us.
Vaccine are what cause
they short are life span! and the hormone they give to animal are killing us!
