Gato. Thx for tackling this sticky topic for millions of concerned parents. Regarding spacing out vaccines and or separating out “combo” vaccines, see the schedule in Japan. https://www.jpeds.or.jp/uploads/files/2020%20English%20JPS%20Immunization%20Schedule.pdf

Note that MMR is separated out and the timeline schedule appears more flexible. Food for thought.

Lastly Pediatrician Paul Thomas, et Al did a pretty robust 10k plus patient study on both schedule flexibility and adherence to any schedule at all. What’s your thoughts?
