So what is the optimal booster cycle? If it is at 53% at 5 months, it is even less effective at 6 months. Every 6 months you get a booster? Forever? is that even often enough? Do the benefits outweigh the risks of 2-3 vaccines a year? Is the infrastructure in place to adminisiter that many doses? To everyone? Or will this become the ultimate class divider?
Small pox was a horrible horrible disease, and 1/3 of the people that received the early vaccines got small pox (usually a less sever case). But they were immune for life. Before Smallpox was eradicated, the vaccines were less and less dangerous. But even with the danger of the vaccine, the goal was to eradicate the disease from the earth, so no one would need to be vaccinated ever again. It does not appear that we can eradicate Covid.
Other vaccines are for less deadly diseases and people don't expect to risk dying from them. There is a ratio of danger from the vaccine vs danger of dying that differs with each disease.
Sometimes I think we are practicing with this vaccine to perfect it enough to work against a worse strain of Covid, that maybe is expected. Because the risks don't seem worth it. Almost all talk of boosters was discontinued when the initial vaccines were distributed. Now we are discussing them again. I never stopped thinking about the booster stuff. That played the most important part if my decision of whether or not to receive an initial vaccine.
The current propaganda is that mixing and matching is safe. I don't want to do that. If I get vaccinated, I want my first vaccine to be the brand of the company that I think I want and can stick with. I am thinking long-term here and always have.
