Congratulations on a brilliantly argued case against the vacuous anti-vaxxers. (Don’t let ill-informed turn you off vaccine, 13/12). I keep wondering why their misleading comments are considered newsworthy. Anti-vaxxers are like hecklers at debates, interrupting the intelligent commentators, militantly obsessed with unlikely detail, expecting to convince without scientific foundation and generally becoming a pain in the backside to everyone else. Thanks to the genius of cartoonist Warren, the adage is proven true that humour wins the debate when all else fails. Backstabbing (with syringes), our former prime ministers step up to vaccinate each other. Great laugh and best cartoon of the year. Alan Sexton, North Parramatta. 20Dec2020.
