GV27:
Sounds like Jansen offers some protection against Delta variant. Keen to know if you can get a single-jab Jansen and then follow-up with a Pfizer later to improve protection.
It will be interesting to know what "mixes" of these can work well. IMO that will transpire over time, its way too soon now to know. But when I roll up for a vaccine, I BETTER NO BE TOLD you are getting Janssen today. If I want Pfizer I expect Pfizer.
