Good luck.
You've got the difficult side because BS is 100 times harder to refute than to spew. I'd expect your opponents to cite obscure, badly performed studies showing autism-vaccine links and unless you're familiar with those studies, you won't know their particular methodological problems.
Perhaps point out the Autism Omnibus Proceedings, where a huge group of people claiming their children got autism from MMR vaccine, were asked to provide their 3 best cases proving a causal link. They lost the trial, badly.
Also, keep hammering vaccine success stories like smallpox eradication, the downfall of polio, and huge drops in incidence for HiB, pertussis, measles, etc.
Thanks, that's a good tip. I'll use that
