When looking at the delta variant, researchers also noted that, though there were good levels of antibodies after the shorter dosing interval, levels were 2.3-fold higher with the longer dosing interval." http://www.bccdc.ca/Health-Info-Site/Documents/COVID-19_vaccine/Public_health_statement_deferred_second_dose.pdf http://www.bccdc.ca/Health-Info-Site/Documents/COVID-19_vacc... This isn't really "new" knowledge, double vaccine shots for other illnesses are usually spaced months apart because it usually boosts immune response and vaccine longevity. I feel quite fortunate that I got Moderna, spaced 7 weeks apart, here in Norway.

My comment comes from chatter I've seen from actual infectious disease specialist and my friend who's has a masters in public health. My friend was assuring people that getting the second dose 'late' wasn't going to be a problem. Other chatter I've seen is that which part of the immune system does the heavy lifting varies depending on the infectious agent. With Covid it's the CD4 T lymphocytes that appear to what's important. Antibodies by themselves aren't that effective. (Notable antibody based therapy has been a bust with Covid19)
