I'm not sure how Bill thinks "vaccines", "health care" and "reproductive health services" will lower the population growth rate by 10 - 15%. Being inoculated from viruses (vaccines), treating diseases (health care) and reproductive health services (fertility) would increase the population growth rate, since a healthy and fertile population grows.
Bill must have different definitions for these terms.
If reproductive health is defined as contraceptives, health care is defined as abortion and euthanization, and vaccines are defined as (???), then his statement makes more sense in terms of reducing the population growth rate by 10% - 15%.
This would explain the sudden explosion of recommendations for pregnant women to get a variety of vaccines they were never recommended to get before. I think many OBGYNs are doing the recommending on good faith, but they're being urged to do it by people I'm increasingly suspicious of.
Interesting.
