Vaccines

We are in for having to boost people's immunity where we've learned that it has been waning. The good news is that there are many working on this next generation, but i think we'll be a year off minimum. So basically, the spike proes little bit like a teen ager getting ready for a night out, trying on 30 different outfits. For coverd that's right. We don't just want to see the tea shirt. We want tosee the whole kit. Bematter, how far off is that where we could make a switch on to something that could give longer protection?
