It means that Trump is still contemplating firing Rosenstein, Mueller, Sessions or all three. Trump's long time accountant Allan Weisselberg has been given immunity in exchange for his testimony. That means that Trump's finances are now front and center. That puts Trump and his entire family in jeopardy. Mr. Weisselberg wouldn't have required immunity unless he was involved in covering up criminal activity for the Trumps.Like a cornered rat Trump will do whatever it takes to survive. The Republicans in Congress have already demonstrated that they will do nothing to stop him.What Trump doesn't seem to understand is that he has no power over the state courts which could pick up the slack if the Mueller investigation is stopped. He also doesn't understand that he can't get involved in an investigation that is investigating him.As the walls close in Trump may do some desperate things. There are no adults left in the White House to control his worst impulses. A Democratic Congress in November may be our best hope to end this nightmare.

Herd immunity does not require 95% or more of the population to be vaccinated.The percentage that needs to be vaccinated to get a herd immunity effect depends on the contagiousness of the disease. Since measles is literally the most contagious disease known to man, it needs the highest vaccination rate for herd immunity to be reliable. Other diseases, with lower contagiousness, need lower vaccination percentages for a strong herd immunity effect. For some diseases, 40% coverage is enough to give some herd immunity. More often, 80-90% coverage is needed.Polio vaccination in the US had well over 90% coverage during the years it was being eradicated. Since polio is less than half as contagious as is measles, that was enough for a good herd immunity effect.

Allergic reactions require immune responses to specific substances.If the immune system were to respond to a substance that comprises more than half of the body’s mass (including most of the material inside and outside immune cells themselves) then obviously no cells would be sustainable.So, it’s impossible. Very rarely should one say something like that in medicine, but in this case it’s necessarily true. Allergic responses to H20 are impossible.However, one more reason why is kind of interesting. We forget how small water is. For example, here is a type-G Immunoglobulin:Now, those knobbly little contours in this illustration are not atoms. They’re peptides folded into domains. Here’s a few examples of those up close in the ubiquitous serum protein Albumin:See what I’m getting at? We’re still not at a molecular level. Here’s Some specific peptides:Finally, here’s a single instance of Leucine (Leu) - one of my favourite amino acids:OK - there’s some hydrogen (white) and oxygen (red) atoms in a schematic sense.See the problem?Water is two hydrogen atoms and one oxygen atom. On an immunological scale it is practically invisible. It is just so tiny. There is no way it could be bound by the sorts of glycoprotein structures that characterise immune system components.In contrast, here’s one of the more significant peanut epitopes, Ara 1:This time the little balls are amino acids again - things the size of that Leucine.See how minuscule water is in comparison?On one level, allergy is an architectural problem. Immune mediators change shape in confirmation (ha! pun) of the presence of an allergen.This simply cannot happen for water, because of sheer scale.
