Tons of nutrients, proper levels of fats, proteins, and carbs. Also, it does pass some antibodies to the child. Also, studies have shown an increase in intelligence for children that were breast milk feed.
Their immune system has not been as exposed to illnesses like their parents have. Not enough time in the world yet. Thats why we use vaccines, so that the immune system will know the illness and be able to eliminate it before it causes harm.
Same reason. Younger kids haven't had the time to build up their immunities. My one year old daughter getting a gever can be more life threatening than my 7 year old having the same issue. Applies for the elderly too, their immune system is slowing down due to age.
Also close. It's because their immune systems are much less effective. Not because of naivete, but because of ineffectiveness. You are exactly right, that's why the very old and the very young can be septic without fevers, why they die from infections at rates much higher than those in the middle.
But that begs the question -- why try to stimulate immunity against a (mostly) adult disease at a point when the immune system is really incapable of mounting much of a response? (which is why it takes 3 serial attempts to get much immunity from the whole process...)
The answer is that the medical community has a bias, a standard perspective which states that immunizations in general have very little capacity to create harm. So they figure, why not?
That's the headspace that the proponents of early immunization come from.
So -- do the proteins in hepatitis B vaccines cross the blood brain barrier, or do adjuvants in the hep vaccine cross the blood brain barrier?
Vaccines are made from attenuated viruses, this renders them inert (harmless to humans) but still allows the immune system to develop against it.
Yes it is possible for many things to cross the BBB. Again though, if there was a wide spread issue, we would know due to the amounts of people that are vaccinated. Around 4 million kids are born in the us, 99% of them are vacinated. Even .5% having an issue would be around 200k per year, every year. In five year, over 1 million would be affected. We would know. You can't hide that much.

So why do infants need antibodies?

Close.
Why do we do ridiculously thorough workups on kids with fevers less than 3 months old but are much more tolerant of fevers in older kids?
