The flu vaccine is a slightly good job of protecting those who received it this year, according to officials at the Center for Disease Control and Prevention.
Preliminary data from the CDC show that the vaccine is about 47 percent effective against all circulating influenza strains, which increased to 61 percent in children aged 6 months to 17 years. The CDC says that an effective flu vaccine reduces the disease level between 40 and 60 percent.
Rates are based on data by February 2 on more than 3,200 people enrolled in the US influenza vaccine efficacy network. Compared to influenza in the period 2017-2018 it was considered to be 25% effective.
Health officials recommend flu vaccination for almost all age groups over 6 months of age.
"The CDC recommends that health care providers continue to administer the influenza vaccine because the flu activity continues and the vaccine can still prevent the illness, hospitalization and death associated with circulating flu viruses or other flu viruses that could be circulating this season. the agency said.
Influenza is currently spread in 47 states, including Alabama.
The flu season generally lasts from October to May, from January to March. It can cause mild to severe illness and sometimes death. Symptoms occur rapidly and may include fever, cough, sore throat, exhausted or exhausted nose, body aches, headaches, chills, tiredness, and sometimes diarrhea and vomiting.
