OK, let's work on the numbers. 1 in a million babies have a severe allergic reaction. There were around 4 million babies born in the USA last year, and assuming all got a full three doses of the vaccine, that would mean 12 million doses, therefore 12 severe allergic reactions.
On the other hand, according to this FOX news article, the number of infants getting a chronic hepatitis B infection halved after routine vaccination, from 260 to 130 (note that not all infants avoid infection because not all are vaccinated, or fully vaccinated, or have an immune reaction). For the infants that were successfully vaccinated, they are protected from hepatitis B for the rest of their lives. http://www.foxnews.com/health/2012/03/28/hepatitis-b-program-helps-cut-infant-infections/
That is the trade-off, 12 severe allergic reactions (which may be life-threatening but won't necessarily cause any permanent damage) for 130 prevented cases of chronic hepatitis contracted in infancy, and many more in adolescents and adults. As the vaccination program continues, the number of cases of liver disease in the population (currently 4,000-5,000 death a year) will steadily decrease.
I would also like to add that the reason why newborn infants are vaccinated is twofold: they are much more susceptible to hepatitis B infections, and hepatitis B screening does not reach all pregnant women. Not all women can afford to pay for screening in pregnancy. There is a lag time for the disease to develop and show up on tests. Women can also be infected between being tested and giving birth. Infants are at a much higher risk of developing the chronic hepatitis that leads to liver disease. Around 90% of infected infants that get hepatitis B get chronic liver disease, compared to only 10% of adults. Around 25% of people with chronic liver disease die of the disease. The CDC has detailed information here: http://www.cdc.gov/MMWr/preview/mmwrhtml/00033405.htm
Your numbers are not real.
We have no idea how many children are injured by vaccines, because most reactions are not even recognized, let alone reported to VAERS. It is estimated that only 1-10% of vaccine reactions ever get reported to VAERS. But "severe allergic reactions" are not the most common severe adverse reaction, so presenting that as the only possible adverse reaction is extremely misleading.
And the estimates of pediatric cases of hepatitis B are just that--ESTIMATES. And they seem to be provided by pharma-funded studies, which were done to justify injecting day-old babies for a disease they are unlikely to be exposed to in their first years of life. If hep B infections were so prevalent amongst newborns and toddlers, there'd be an awful lot of babies and toders kicked out of day cares. And we would all know at least as many families who have been through hep B diagnosis as families with autism diagnoses.
