Just for the sake of geeking out, here are some definitions from other dictionaries I could find: Macmillan [1]: someone who believes that vaccinations are harmful to human health and so refuses to vaccinate their children against childhood diseases Lexico (Oxford) [2]: A person who is opposed to vaccination. Cambridge [3]: someone who does not agree with vaccinating people (= giving them injections to prevent disease) and spreads and encourages opinions against vaccines Wikitionary [4]: A person who opposes vaccination, as for its purported dangerous effects. Dictionary.com [5]: a person who distrusts or is against vaccination, especially a parent who refuses to have a young child vaccinated. American Heritage [6] and Longman [7]: It seems that they do not have an entry. Collins also doesn't have an entry, but apparently there was a suggestion for adding it in 2015.
