US vaccines? I Thought in the beginning they already say people who are pregnant and have diseased are not allowed to take the vaccine. 

Why though? Chemicals in it? 

For the U.S. approved COVID vaccines even though clinical trials haven't been extensive CDC has recommended pregnant women get vaccinated since in addition to an increase in premature birth they are more prone to serious illness, hospitalization and death from COVID.   They also say it's a personal choice.

Limited data are available about the safety of COVID-19 vaccines for people who are pregnant

Based on how these vaccines work in the body, experts believe they are unlikely to pose a risk for people who are pregnant. However, there are currently limited data on the safety of COVID-19 vaccines in pregnant people.

• Clinical trials that study the safety of COVID-19 vaccines and how well they work in pregnant people are underway or planned. Vaccine manufacturers are also collecting and reviewing data from people in the completed clinical trials who received vaccine and became pregnant.
• Studies in animals receiving a Moderna, Pfizer-BioNTech, or J&J/Janssen COVID-19 vaccine before or during pregnancy found no safety concerns in pregnant animals or their babies.
