J&J is a one-shot and done adenovirus-based vaccine. So a second shot, 6-9? months out, would be a two-dose and done and give over a year’s protection possibly up to 18 months??? -

that timeframe needs review of course. But if HCWs were going 9 months on a single dose and not being infected, there must have been some sort of protection still active at 9 months, right?

What I hear you saying is, two shots per year, or once every six months and that should do the trick.

One or two and done you say?

Speaking from personal experience, having had the CHINA VIRUS early on in 2020, and then getting the J&J Shot in April of 2021, I still have the antibodies present. I'm being tracked as part of a study related to people with genetic immuno-deficiencies who are on Humira for them. I submit to a blood test every two months to track my antibodies. My last test, 1.5 months ago showed I still have high antibodies. My next test is in 2 weeks.

As of my last test and visit with my specialist, no 'booster' is needed. The only conclusion I can come to is that the antibodies developed having had the CHINA VIRUS are durable and long lasting. At least they are for me.
