Yup. You can't catch the same strain again only drastic mutations which are caused by adapting to vaccines most of the time so they don't help. And it's all part of virus stages. It's only transmisible in sheding stage, which is the symptoms such as running nose sneezing and coughing and build up in lungs. They say follow the science but don't do it themselves. Natural immune system can last over a year and the doctors say vaccines shouldn't be given to people who had it because it will destroy their Natural antibodies and the monoclonal antibodies if you got that treatment. And they only last up to a few months under the assumption they work like a normal vaccine, which they don't. And the twits on Twitter say to get them back to back but even normie sources say to wait 2 months between each dose because the second one was always booter too since they know it doesn't work. Vaccines also have inactive antibodies that only mimic real ones to trick tests. They just have lies on top of lies ad infinitum.
