I'm not convinced that there will be boosters, or at least not as frequently as some are saying. Right now, it's all speculation. So far, there have been no studies showing people who have been vaccinated who later lost the immunity. Covid and the Covid vaccines just haven't been around long enough. They are taking an educated guess and also trying to be prepared in case boosters are necessary. But there is no data yet that actually says they will be.
Nice job, Canada!

So far the studies from people naturally infected show there are still anti-bodies a year later. The studies showed that the more severe the infection the higher level of antibodies remaining. All of the people in the study who were hospitalized showed high levels but the level of coverage decreased in people who were younger and/or mildly infected. The vaccines are designed to simulate to your immune system a full blown Covid case so should work as well or even better than the people with severe infections.
We are trying that now here in the US. Slowing down the paceSometimes the turtle wins the race
. For WDW the UK and Canada are both doing very well with vaccinations so a large portion of the normal International tourists may be back sooner than a lot of people expected. Maybe not this Summer, but possibly by the 50th on Oct 1.

You'd be just as likely as anyone else. I'd be left out (I really don't personally want a check anyway)I got vaccinated in January. Can I still get a check?
They were already ready working on that if needed. For Pfizer I was told they were running tests on Phase 1 only so they'd likely be ready to go. But for now we don't need them so it hasn't gone any further.
Using the mRNA technique, not long at all. They just need to know the complete amino acid sequence of the spike protein variants, backwards code them into mRNA and multiply the sequence exponentially through a PCR machine. The beauty of the mRNA technique is how easily you can make them.
Design won’t take long at all thanks to mRNA and I imagine they could ramp up in the same facilities used today so manufacturing would be quick to ramp up too. Assuming both Pfizer and Moderna were involved they have shown they are capable of delivering over 100M doses a month combined so 2 to 3 months for enough doses for everyone who wants one. Assuming a pace of 4M+ doses a day administered we could be done in about the same amount of time. So roughly 2-3 months after they start delivering the vaccine boosters we could have everyone who wants one vaccinated.
It depends on what happens with the patent waiver fight. There are plenty of places all over the world that can start ramping up manufacturing of the Pfizer or Moderna or AstraZenneca vaccines if they are allowed.
It would be nice if they came up with a better policy than "hope no one notices."
My husband and I were not wearing masks, and no one even seemed to notice. It may have helped that at least 5 employees (including one manager) were very visible and not wearing masks. Contrary to what you see on social media, most people mind their own business and try to avoid confrontation.

In Disney terms if they started today the US population could be done with the boosters in time for the 50th Anniversary
