"or if it is the sense of security conveyed by having an immunization shot that really drives the sociability." Yeah, not accounting for that hurt the article's credibility a bit for me. It's more obvious when you picture yourself as the person concerned enough to get a vaccine. Maybe enough go reduce contact a bit just before that as it's on your mind. Then, doc says you're safe and good to go. Ok, now that the risk is knocked out, lets go out and have some fun with the crowds. Easy to see a non-parasite explanation for it.
