JEFFERSON CITY — Missouri received about 22,000 doses of an H1N1 vaccine that has been recalled.
State health officials said doses of the recalled vaccine were sent to 75 counties across Missouri.
Hundreds of thousands of H1N1 shots for children have been recalled nationally because tests indicate the vaccine doses lost some strength. Government health officials said the vaccine is safe and effective, and the parents of children who received the vaccine should not be worried.
Health officials said the doses affected by the recall are pre-filled syringes for children younger than 3 years old.
