The CDC has been racing to increase rates of vaccination among infants by tracking newborns on the immunisation rolls
Nearly 30 million new US babies were immunised during 2016, according to data released by the US Centers for Disease Control and Prevention.
The 35,840,992 infants aged up to six months received tetanus-diphtheria-pertussis (Tdap) booster vaccines, improving the rate of immunisation from 2015 by more than 500,000 infants.
The CDC has been racing to increase rates of vaccination among infants, estimating that the immunity of young children effectively spreads from mother to child. This particular government data shows that this is working and is a big reason why infant immunisation rates have increased so quickly.

About 25% of babies receive a Tdap vaccination at birth and 29% received two or more doses by the time they reached their second birthday. States with better protection are able to provide both vaccines at a lower cost.
So what has allowed immunisation rates to improve dramatically in the US?
Cameras monitored neonatal vaccinations in 2017 in six states, which revealed a one-year increase in immune protection and a one-year decrease in the infant mortality rate.
The report suggested that catching flu during the first month of life could reduce the mortality rate by 20% to 30%. The study did not say what proportion of children were vaccinated in each state.
The CDC has been tasked with encouraging universal immunisation of children of all ages.
