Centers for Disease Control and Prevention on Thursday made another call for vaccination following the H1N1 influenza virus still causing illness and death.

"Many people are still susceptible to this virus and would benefit from vaccination. We want to avoid complacency. We have a very good supply of the H1N1 vaccine all around the country," said Dr Anne Schuchat, director of the National Center for Immunization and Respiratory Diseases at the CDC.

According to Schuchat the number of Americans who received H1N1 vaccines was 60 million. Further 136 million doses were already available for access with the government and accessing them would not be tough.

Delaware, New Jersey, Maine and Virginia still state widespread H1N1 activity.

According to the CDC, last week there has been a slight spurt in flu-like illness cases coming at doctor’ offices and emergency rooms. A rise in influenza deaths and pneumonia has also been reported in the past week.

The CDC is starting a campaign to encourage people to get vaccinations this weekend. The campaign will be called National Influenza Vaccine Week.

Doctors are advising that children under the age of 9 should get their second dose of H1N1 vaccine. They said it with the flu season being prevalent.
