So far, more than 303,000 doses of the 1.3 million ordered have arrived. They have been distributed to 540 health care providers - or nearly one-third of the 1,800 providers that have ordered the vaccines.
At the Burlington County Health Department, Rebecca Fulton, who is expecting, was able to get her shot on Friday.
As for why she got it, she said "Safety for myself, my child, and my O.B. recommended it."
Hundreds of expectant mothers showed up for one of the first public H1N1 flu shot clinics in New Jersey. The Burlington County Health Department is giving their first doses to pregnant women who are at a greater risk for complications.
While women rolled up their sleeves, there were still a few concerns.
Health educator Holly Cucuzzella says some women were concerned because the injection contains thermerasol, a perservative some people previously thought could cause problems.
But, she said not to worry.
"There has never been any scientific evidence to show thermerasol affects a mother or a fetus and the CDC says women should be vaccinated regardless of the thermerasol status in the vaccine," Cucuzzella said.
As an expectant mother herself, Cucuzzella also got the shot.
Production of the vaccine is running several weeks behind schedule.
