Just to be clear, I’m not saying COVID necessarily makes you immune, there have been people who get COVID twice as we all know, but many studies are showing lasting immunity. Much like the vaccines work 90% of the time, but then there are breakthrough cases.
This Q is about whether the body creates some memory and then a single shot builds on that in the immune system.
Scientists are studying it, and not only in the small study I posted.
Comparing the standard two shots to having had COVID is not this Q. This Q is two shots compared to covid plus one shot.
There is also a mix study happening in the UK. One dose AstraZeneca one dose Pfizer. Of course no one should be mixing and matching right now except in very unique cases (I know of one person who did mRNA first dose and J&J second dose) but so far the mix study is showing a strong immune response.
Moderna was being tested in half dose after the initial approval, I don’t know if that study was completed. J&J has a two dose study going on. Both make sense as a hypothesis worth testing, but that doesn’t mean we start playing with how it is being administered now.
Accepting that scientists are interested in the results of single vaccine after COVID doesn’t mean people should only get one vaccine, it just means science continues to look at how the immune system and vaccines work regarding COVID and possibly the science will evolve to different recommendations.
Doctors right now are only going to prescribe (recommend) it be given how the FDA approved it, which is two shots period, which they should and makes sense scientifically currently.
If one dose is sufficient for people who had COVID it could really help in countries like Brazil and India.
