There is no logic to your 'prediction' but never mind.I am predicting covid will get worse for the people that can’t get vaccines or booster. Here people have chosen not to take them but for most of the world people can’t get them. In the US we should always have high availability but for most of the world that will never be the case. What about these people if we put evolutionary pressure towards making this virus more like merricks disease in its response to vaccines?
Do you know anything about Israel’s covid response? They hold just about every record for vaccinating their population along with the research to follow it. When information about this comes out of Israel it’s generally pretty accurate. My guess is Monday when ‘they’ (the government who knows?) meet about booster, it will start to catch traction. They just don’t want to say that because even more people might switch from the wait and see to No camp.
Israel is frequently cited as the best vaccine roll out but actually only 57% of the population has had both doses which is well below the level needed to stop virus circulation. Other countries are very close now including the UK. What Israel did do is vaccinate their 57% very quickly, so they are the ''longest' vaccinated population. The length of time immunity lasts however is very complex and also individual dependent. Older people tend to have a poorer response to the vaccine in the first place and weaker long term antibody levels, and how do you actually measure 'immunity'. Antibodies can be measured but not T-cell related immunity which are known to play a major part in the COVID immune process. Repeat infection of younger healthy individuals is very rare even now suggesting immunity lasts for a reasonable length of time. The biggest risk comes from a new vaccine escape variant where immunity to current strains would be of little benefit.
Having said all of that the vaccine doesn't rely on a single antigen to provide immunity and the vaccine itself can be changed to deal with changing strains. It is very likely that some people in the world will never get the current vaccine and will jump straight to the next version, after all vaccinating the entire world once is likely to take years.
